When was the last time a “12-week lead time” helped your project stay on schedule.

The Hidden Cost of Custom Everything

There’s a trend in hydraulics toward custom solutions for every application. Custom manifolds. Custom valve assemblies. Custom pressure settings. It sounds sophisticated until you face real-world consequences:

  • Production schedules built around hoped-for delivery dates
  • Emergency repairs waiting on special-order components
  • Inventory nightmares from supporting dozens of unique part numbers
  • Engineering time spent specifying variations that add complexity without performance benefit

Sometimes the smartest solution is the one that’s actually available.

When Standard Means Better

Bosch Rexroth’s DBD 6-30 pressure relief valves prove that standardized doesn’t mean compromised. These direct-operated relief valves combine proven performance with the practical advantage of consistent stock availability.

Four sizes. 50 to 330 l/min flow capacity covers most mobile and industrial requirements.

Seven pressure ratings. From 25 to 630 bar—low-pressure mobile equipment through high-force industrial presses.

Multiple configurations. Cartridge, threaded, or subplate mounting. Tool-adjustable or hand-adjustable. Standard or enhanced corrosion protection.

The combinations you actually need? Ready to ship.

One Valve. Both Strengths.
Why Smart Designers Choose Stocked Pressure Relief Valves

Reliability Through Simplicity

DBD valves use direct-operated design where system pressure acts directly against a calibrated spring. When pressure exceeds the setting, the valve opens proportionally.

No pilot stages creating delays. No complex controls introducing failure points. Just mechanical reliability that works the same way every cycle.

This simplicity delivers real advantages:

  • Predictable response when pressure approaches limits—no pilot delays, just direct mechanical action.
  • Straightforward service when maintenance is needed—springs and seals, not multi-stage troubleshooting.
  • Consistent performance across temperature ranges and fluid conditions because mechanical operation doesn’t depend on pilot signal quality.

Built for Tough Conditions

Pressure relief valves often end up in exposed locations where environment challenges longevity. That’s why DBD valves offer corrosion protection levels matched to actual conditions:

  • Standard protection handles typical indoor industrial environments.
  • J3 protection (240-hour salt spray resistance) suits outdoor installations, mobile equipment, or humid conditions where condensation occurs regularly.
  • J5 protection (720-hour salt spray resistance) addresses marine applications, coastal facilities, or chemical processing where standard coatings fail within months.
  • The protection isn’t cosmetic—it’s functional reliability. Corrosion affects spring characteristics and sealing surfaces. Protected valves maintain calibration where unprotected alternatives degrade.

High Pressure Without Hesitation

Maximum ratings of 630 bar aren’t theoretical—they’re proven operating capability. Steel construction, hardened sealing surfaces, and precision manufacturing ensure DBD valves maintain performance and reliability when actually operating at high pressures.

For systems running 315 bar, 400 bar, or 630 bar, you’re not pushing design limits. You’re working within validated capability backed by decades of field installations.

The Availability Equation

Here’s what changes when critical components are consistently available:

  • Design confidence – Build schedules around actual delivery, not hoped-for dates.
  • Simplified inventory – Stock one reliable valve family instead of maintaining emergency supplies of multiple alternatives.
  • Faster emergency response – When pressure protection fails, replacement arrives in days.
  • Reduced planning stress – “Is it available?” stops being a question you ask weekly.

Quality That Shows Up Consistently

Rexroth manufacturing standards ensure every DBD valve meets specifications:

  • Precision machining of sealing surfaces
  • Controlled spring calibration with verification
  • Functional pressure testing before shipment
  • Consistent performance across every unit with the same part number

When you install a DBD valve, it performs like every other valve with that specification—predictable, repeatable, reliable.

When Simple Wins

Sophisticated solutions have their place. But when you need reliable pressure protection that’s available when projects demand it, proven when systems depend on it, and consistent when production requires it—standardized excellence beats custom complexity.

DBD 6-30 pressure relief valves: the smart choice that’s actually in stock.

High-Flow Just Got Smarter: Inside the New CytroPac 2X Small Hydraulic Power

You spoke, we engineered. How direct customer feedback shaped the next evolution of compact, intelligent hydraulics.

When Bosch Rexroth introduced the original CytroPac, it fundamentally challenged what a hydraulic power unit had to look like. It eliminated sprawling, leaky 100-liter oil tanks, silenced shrieking pumps, and integrated the variable-frequency drive right on top of the power unit.

It quickly became the benchmark for machine tools and compact industrial automation. But at Bosch Rexroth, being an industry standard is just the baseline.

Over thousands of operational hours on shop floors worldwide, machine builders and maintenance managers gave us clear feedback on how to make CytroPac even better:

  • “We love the compact footprint, but we need more modularity to mount our own valves and handle large return flows.”
  • “Give us industrial-grade connectivity and continuous condition monitoring.”
  • “Help us cut energy consumption and CO₂ even further.”
  • “Make setup, maintenance, and visual diagnostics simpler for operators on the floor.”

The result is the CytroPac Series 2X—a power unit perfected by you.

Here is a closer look at what’s new in the 2X evolution and what it means for your machines.

Modularity That Fits Your Circuit, Not Ours

In the past, integrating directional or proportional control into a compact hydraulic circuit often meant mounting an external manifold block nearby, running extra hoses, and wasting valuable floor space.

The CytroPac 2X solves this with pre-engineered, factory-matched Functional Modules:

  • Standard Return Filter Module (M1): 10 µm filtration with integrated cold-start suppression monitoring to prevent false clogging alarms when oil is cold.
  • Leakage Oil Module (M2): Dedicated dual-return routing with built-in diffusers for pressure-free return of large volume flows, preventing oil foaming and aeration.
  • Valve Module (M3): An integrated NG6 (ISO 4401-03-02-05) interface plate mounted directly onto the power unit. You can now bolt standard Rexroth directional valves or multi-station manifolds straight onto the CytroPac.
  • Filter Module with DBV (M4): Integrated system pressure relief directly combined with the return filter.

Whether you need a standalone pressure supply or a complete, self-contained hydraulic control station, the 2X configures to your exact footprint.

Up to 80% Energy Savings: The Math Behind the Machine

Energy costs and carbon reduction mandates are no longer abstract targets—they directly impact operational margins.

The CytroPac 2X pairs high-efficiency motor options (including an IE5 PMSM servo motor on the 4.0 kW model and an IE4 asynchronous motor on the 2.2 kW model) with Bosch Rexroth’s Sytronix variable-speed pump drive.

Instead of running a fixed-speed motor that constantly dumps unused oil over a relief valve at high pressure, CytroPac 2X dynamically matches pump speed to the exact flow and pressure the cycle demands. In holding-pressure or idle phases, the motor slows down or drops into an intelligent sleep mode, slashing energy consumption by up to 80%.

The CytroPac 2X

Big Cooling Power in a Tiny 20-Liter Tank

How do you run 280 bar pressure and up to 38.5 l/min of flow out of a unit with only a 20-liter oil tank?

Traditional hydraulics rely on a massive 60 to 100-liter reservoir simply to let trapped air bubbles escape and allow oil to cool down before being drawn back into the pump. CytroPac eliminates this bulk using two patented innovations:

  • Degassing-Optimized Tank Flow: CFD-designed internal geometries guide returning fluid along precise paths that de-aerate oil almost instantly.
  • Heat Pipe Cooling Technology: Heat pipes transfer up to 2 kW of heat away from both the submerged motor/pump assembly and the oil reservoir straight into a heavy-duty aluminum cooling plate.

The result? 80% less hydraulic fluid to buy and dispose of, a 50% smaller machine footprint (1,200 cm² vs. 2,400 cm²), and an enclosure that completely muffles pump noise—operating at conversational sound levels even under full load.

Native Connectivity: Smarter Monitoring, Zero Hassle

Gone are the fragile RJ45 and Push-Pull connections of earlier units. The CytroPac 2X standardizes on rugged M12 Multi-Ethernet connectors, allowing seamless integration into fieldbus networks (Profinet, EtherCAT, Ethernet/IP, and Sercos).

The integrated frequency converter acts as an edge sensor node. In addition to standard digital switches, the 2X offers continuous 0–100% oil level sensing and 0–60°C continuous temperature logging. Connected to CytroConnect Solutions, your maintenance team can predict filter clogging, track thermal performance, and plan component servicing long before unexpected downtime occurs.

And for operators on the floor:

  • A bright Status LED bar integrated directly into the top hood provides immediate visual status from any viewing angle.
  • An optional 4.3″ HMI Touch Display right on the housing gives technicians instant readout of operating pressure, oil temperature, motor speed, and active alarms.
  • Our Commissioning Wizard gets the unit running in minutes via the USB service interface.

Designed for Global Deployment

For machine builders exporting to North America, regulatory certifications can be a costly bottleneck. The CytroPac 2X features optional cULus listing complete with an industrial-grade steel hood, alongside integrated Safe Torque Off (STO SIL 3 / PL e). You can specify one global design, confident that it meets electrical and mechanical safety standards anywhere in the world.

The Bottom Line

The CytroPac 2X proves that component evolution doesn’t happen in a vacuum—it happens when engineers listen to the people running the machines every day.

  • More modularity for custom control circuits.
  • More connectivity for Industry 4.0 monitoring.
  • More energy efficiency to cut your power bills and carbon footprint.
  • More simplicity for the technicians on your shop floor.

Aluminum framing can elevate safety in manufacturing

In the fast-paced world of manufacturing, where efficiency and productivity are paramount, safety should never be compromised.

Yet one aspect often overlooked in ensuring shopfloor safety is the incorporation of aluminum framing. It’s the backbone of any facility, but it’s frequently deemed less important compared to the conveyors or assembly processes executed on it. It’s time for manufacturers to change their perspective and start viewing aluminum structural framing as a foundational element to their operations.

Sustainability and adaptability: building a safe foundation

The versatility of aluminum framing in manufacturing cannot be overstated, especially in a landscape where sustainability, adaptability and compliance are essential for maintaining a safe working environment. Aluminum framing systems play a role in helping ensure the safety of workers. Companies can reach out for assistance with machine guarding, ergonomic design and resources to stay in compliance with electrostatic discharge (ESD) regulations. Aluminum framing is foundational in addressing these concerns.

A multi-functional and recyclable resource, aluminum framing is synonymous in meeting sustainability goals. While the most robust aluminum framing on the market tends to outlast most employees, when its purpose as one structure is fulfilled, it’s designed to break down and be reconstructed as something else.

Machine guarding: protecting workers, protecting lives

Compliance with regulations, particularly concerning machine guarding, is a top priority for manufacturers looking to enhance safety on their factory floors. With the increasing adoption of robotic applications and high-speed conveyance in industrial settings due to automation, aluminum framing plays a crucial role in meeting industry regulations and protecting workers from potential hazards. Whether it’s a collaborative robot (cobot) or a transfer system with speeds of up to 150 meters per minute, there must be adequate enclosure and guarding to stay within safety standards.

A key consideration is the concept of finger-safe enclosures, which prevent accidental contact with hazardous components, reducing the risk of injury and ensuring a safer working environment for all.

ESD compliance: safeguarding sensitive environments

In addition to physical safety measures, aluminum framing also plays a vital role in addressing electrostatic discharge (ESD) concerns, particularly in workstations where sensitive electronic components are handled. Aluminum framing solutions can be instrumental in constructing ESD-safe environments, as well as safeguarding against potential damage to circuit boards and delicate semiconductor processes.

The demand for electronic devices amplifies the need for such measures, making ESD compliance an essential consideration in aluminum framing design. By incorporating ESD-safe aluminum framing solutions, manufacturers can mitigate the risk of damage to equipment and ensure the safety of their workers.

Prioritizing safety through aluminum framing

Aluminum framing is not merely a structural component of a factory floor; it’s a critical element that directly impacts the safety and well-being of workers. Every manufacturer must prioritize safety by rethinking how they approach aluminum framing design and implementation.

By recognizing the importance of aluminum framing in maintaining a safe working environment and prioritizing safety in aluminum framing design and implementation, manufacturers can enhance efficiency, mitigate risks and ensure the long-term success of their operations. It’s time to give aluminum framing the attention it deserves and use it as the powerful tool it is to elevate safety in the manufacturing industry.

Aluminum Framing as the Backbone of a Successful Data Center Infrastructure

In an AI-driven shift, data center construction is growing at a rapid pace.

In 2025, the data center construction market was estimated at 261 billion and expected to steadily grow at a 12% CAGR through 2033.

To meet the demand, additional data centers need to be built with speed and longevity in the forefront. After all, a data center malfunctioning can be detrimental. That’s why a successful data center needs to be built correctly – before the servers even enter the building.

A Tale of Two Materials: Steel and Aluminum

In the high-stakes world of data centers, where every degree of temperature matters, installation efficiency and overall reliability are paramount.

While steel is often viewed as the preferred material due to its strength and structural integrity, this emphasis on efficiency and reliability give aluminum framing its edge. Compared to steel, aluminum framing is more lightweight for easier handling, boasts a stronger strength-to-weight ratio, and greater thermal conductivity.

When purchased in bulk for a large project like constructing a data center, aluminum framing is often more economical, and quicker for construction workers to handle in installation due to being lighter.

Depending on the application, both steel and aluminum can often work together for the overall build. Steel does greater load-bearing strength and if the weight requirements extend aluminum’s specification, using steel is a solution. But in key data center construction applications like hot aisle containment, cold aisle containment, false floors, and even server racks, aluminum framing is a smart start to a successful data center.

Top Aluminum Framing Applications in Data Center Construction

While aluminum framing can be used in more applications, the strengths of the material shine brightest with the following applications:

  • Hot Aisle Containment
  • Cold Aisle Containment
  • Server Racks
  • False Floors

Hot Aisle Containment

Temperature management is a critical consideration for data centers. Hot aisle containment systems are paramount to reduce energy consumption and improve overall efficiency by preventing the mixing of hot exhaust air and cold supply air. With its ability to form an air-tight containment seal, thermal-conductivity benefits, and easy installation, aluminum framing is the ideal material structure for these critical enclosures.

With a modular aluminum framing system, it can also adapt and be reconfigured if the data center needs to shift as technology evolves.

Cold Aisle Containment

Cold Aisle Containment encloses the aisle where cold supply air is supplied to equipment, using panels and doors to separate it from hot exhaust air. All the same benefits of aluminum framing from hot aisle containment apply to this application.

Server Racks

Beyond aisle containment and temperature control, aluminum profiles are revolutionizing server rack construction. Steel racks will be heavy, which makes them hard to move and limits their adaptability. Aluminum profiles, however, offers a superior alternative that are not only incredibly strong but also remarkably light, facilitating easier transportation and deployment.

False Floors

Data centers require raised floors, also known as false floors, that are elevated between 1-2 feet and support cable management, as well as a distribution system for cold air to server racks. With its impressive strength-to-weight ratio and easier installation, aluminum framing makes an efficient material for false floors that improve cooling efficiency by supporting underfloor airflow.

Beyond its technical strengths, aluminum framing provides unmatched aesthetics – clean lines, precision surfaces, and modularity create an impressive environment that is not just functional, but visually impressive. In a rapidly changing market, where efficiency, speed, and precision are paramount, a material solution that looks as sleek as it performs speaks volumes about the quality of the entire infrastructure.

Which linear guide is right for my application?

Whether it’s dirt, clean rooms, high dynamics, or limited installation space: If you are clear about the loads, environment, and service life, you will usually find the right solution in the Rexroth standard portfolio.

Linear guides rarely get the spotlight, but they play a central role in mechanical engineering and factory automation. They guide linear movements precisely and reliably under defined environmental and load conditions – as efficiently, compactly, and with as little maintenance as possible. But which linear guide is suitable for dirt, vacuums, clean rooms, extreme temperatures, high dynamics, or limited installation space?

In this blog post you will learn which selection criteria are crucial for linear guides and which applications you can realize particularly economically with our proven standard solutions. If you have special, individual requirements, our experts with decades of application knowledge will be happy to assist you.

Tip: For an overview of the most important types of linear guides – from linear bushings to profiled rail systems and cam roller guides – please visit our linear guides product page.

Which linear guide for which application?

Rexroth linear guides can be found in virtually every industry – from machine tool manufacturing to medical technology, from the food and packaging industry to wood processing, from semiconductor and electronics manufacturing to battery production. The common denominator: the possibility to implement almost any application quickly and cost-effectively. The advantages of the broad standard portfolio of linear guides are a wide selection of proven, quickly configurable solutions with global availability as well as shorter project lead times and machine designs tailored to specific needs. Below are some examples of industry-specific applications and customized solutions:

1. Linear guides for special environmental conditions

Many environments expose linear guides to dirt and contaminants, such as in woodworking and stone processing. Profiled rail systems with special seals (either integrated or as attachments) and the fully sealed standard linear bushings from Bosch Rexroth have proven to be a cost-effective solution for these applications.

Harsh environmental conditions: Double-lip seals protect the linear guides in woodworking and metalworking from dirt and contamination.

The all-metal ball rail systems for extreme conditions NRTVG (NRII Temperature Vacuum Graded) withstand extreme temperatures from -30 to 200°C. They impress not only in cold rooms or glass manufacturing, but also in vacuum environments – such as those encountered in wafer and electronics production. The same applies to the all-metal standard linear bushings.

A risk of corrosion exists in the case of contact with acids, alkalis, or electrolytes in electroplating or battery production, as well as during steam sterilization in the medical or pharmaceutical environment. Linear guides made of NRII (corrosion-resistant steel) and hard chrome plated and coated versions (e.g. zinc-iron) prevent these damaging effects. For use in dry rooms, the Rexroth standard portfolio also includes linear guides with resistant plastics such as POM as well as special lubricants.

Miniature ball rail systems and corrosion-resistant profiled rail systems, among others, meet the requirements of various clean room classes in semiconductor and electronics production.

Tip: Depending on the required clean room class, standard versions are often sufficient.

Linear guides are also indispensable in the food sector, especially in packaging and final inspection. The Rexroth ball rail systems in corrosion-resistant NRII or NRFG design (NRII Food Grade) are particularly well suited to these environments. Process-related guiding tasks without direct food contact (e.g. bottle fillers, film wrapping machines, or bag forming, filling, and sealing machines) also benefit from the easy-to-clean, all-metal linear bushings.

2. Linear guides for precision, dynamics, and limited installation spaces

Ever-increasing automation is also pushing the boundaries of accuracy, dynamics, and installation space. When it comes to precision, the roller and ball rail systems RSHP/BSHP lead the way in the Rexroth standard portfolio. Why? A patented entry zone in the runner block ensures optimal smooth running – from workpiece machining, feeding, handling, and assembly to cover plate and laser cutting or 3D printing.

Functional principle of the precision ball rail system BSHP in cross-section: The graphic shows how elastic steel bearing plates enable the balls to enter the bearing zone harmoniously and without impact.

Ball rail system BSHP: Thanks to elastically deformable steel bearing plates (2), the entry zone adapts individually to the current operating load of the runner block (1). The balls (4-7) enter the bearing zone between the runner block and the ball rail (3) smoothly, i.e. without any impulse loads.

Tip: Linear axes and multi-axis systems equipped with BSHP linear guides also achieve maximum precision and dynamics.

Symbolic image for maximum speed: A sprinter in starting position next to two high-speed runner blocks on a blue stadium running track.

Short cycle times require high speeds: The high-speed runner block from the Rexroth standard portfolio reaches a record-breaking 10 m/s. Typical application areas include plastic injection molding, pressing and joining, laser cutting, and handling with long travel ranges. The Rexroth standard linear bushings and standard ball rail systems in small sizes also move quickly at speeds of up to 5 m/s.

Incidentally, the durable cam rollers from Bosch Rexroth are also ideally suited for fast movements up to 10 m/s.

Integrated additional functions save installation space and reduce costs. How? For example, through the temperature control function TCRS, which ensures thermal stability in high-precision workpiece machining, or through linear guides with integrated measuring systems.

Good to know: Both options can be retrofitted.

Do you want to implement demanding applications in the mid-range price-performance segment economically? Then the all-round guide system BSCL (Ball Rail System Compact Line) is the right choice. Why? Fast selection, configuration, and ordering, combined with the familiar Rexroth quality, many cost-reducing features, and rapid delivery (worldwide from stock).

Incidentally, the price-optimized BSCL line will be consistently expanded in the coming years to cover even more requirements and applications at an optimized price.

Downsize Your Drive, Not Your Power: The A3V Pump Changes the Sustainability Equation

For years, the path to sustainability in industrial hydraulics seemed to involve trade-offs. Gaining energy efficiency often meant complex system designs or accepting limitations. But what if you could achieve massive energy savings while also reducing investment costs, simplifying your machine build, and improving performance?

This is the new reality made possible by the Bosch Rexroth A3V pump platform, a highly efficient, high-speed variable displacement pump designed specifically for modern, speed-controlled industrial applications.

The Speed-to-Torque Revolution

The fundamental principle behind the A3V is a game-changer for machine design. In a speed-variable pump system, the required motor torque is directly related to the pump’s displacement and speed. By designing the A3V to operate reliably at exceptionally high speeds—up to 4000 rpm—we’ve flipped the traditional design equation.

This higher speed allows the pump to achieve the same flow rate with a smaller displacement, which in turn reduces the required motor torque by up to 30%.

What does this mean for you?

  • Downsize Your Motor: You can now use a smaller, less expensive servo motor.
  • Reduce Drive Costs: A smaller motor often allows for a smaller, more cost-effective converter.
  • Eliminate Liquid Cooling: In many cases, the smaller servo motor can be air-cooled, eliminating the cost and complexity of water-cooling circuits.

The result is a direct reduction in both initial investment cost and long-term operating costs.

Efficiency You Can Measure (And Hear)

The A3V platform isn’t just fast; it’s a new benchmark for efficiency in medium-pressure hydraulics. With a total efficiency of up to 93%—five percentage points higher than previous generations—it minimizes energy losses during operation. For cyclic applications like injection molding or presses, this can translate to overall energy savings of up to 80% compared to constant-speed systems.

We also engineered the A3V for quieter operation. Its design significantly reduces pressure pulsation, a primary source of hydraulic noise. This leads to a quieter machine, a more comfortable working environment, and less vibrational stress on the entire system.

Built for the Future of Hydraulic Drives

The A3V platform is purpose-built for the demands of modern electro-hydraulic systems.

  • Recuperation Ready: In applications like lowering a lifting platform or counter-holding a die cushion, the A3V can act as a motor, driving the servo motor as a generator to feed power back into the grid or intermediate circuit.
  • Unlimited Start/Stop: Designed for highly cyclic applications, it has no restrictions on start/stop cycles or prolonged pressure holding.
  • Dynamic and Variable: The combination of variable displacement and variable speed allows the system to achieve any operating state with optimized energy use, from high-flow movements to high-pressure holding with minimal torque.

The Smart Choice for Sustainable Hydraulics

The A3V pump platform proves that sustainability and cost-efficiency can go hand-in-hand. By enabling the downsizing of core drive components while delivering best-in-class performance, it represents the next generation of intelligent, medium-pressure industrial hydraulics.

Hydraulics just got a modern user interface: Easy2Connect App

Bosch Rexroth’s Bluetooth-enabled valve solution brings commissioning, tuning, and diagnostics to your iPhone or iPad through the new Easy2Connect app, now live in the US Apple App Store. What used to require a laptop, a cable, and a pile of guesswork is now a quick pairing and a clear dashboard.

Here’s how it works: add the compact Bluetooth dongle (R901505294, VT-ZBT-1-1X) to your valve, open Easy2Connect, and you’re in. You can see configuration at a glance, adjust dynamics with guided steps, and capture error messages in seconds. Whether you’re bringing a line online or chasing down a stubborn issue, you get actionable data where it matters—right at the machine.

It’s time to pair up your valves and get commissioning down to a science.

If you’re running valves like 4WRAE6-3X, DBETA-7X, DBETE-7X, 3DREA6, or Z3DREA6, (Data Sheets Link) this is a simple upgrade that makes a noticeable difference.

Many users already have the valves on-site; adding the Bluetooth “black box” unlocks the digital layer that speeds commissioning, lifts productivity, and maximizes availability. And because it’s retrofit-friendly, you can standardize the experience across mixed fleets without a major overhaul.

The launch starts with iOS in the US, with Android submission to the Google Play Store coming next. Europe and China will continue to run their regional app versions. If you’ve been waiting for the US release, your wait is over, download Easy2Connect, order the dongle if you don’t already have it, and turn your hydraulics into a connected, intuitive system.

Why Machine Tool Builders Are Rethinking Hydraulic Power Units

Bosch Rexroth Web Editorial TeamEditor

When every square inch of factory floor space costs money, why are machine tools still using bulky hydraulic power units that waste half their footprint?

The Installation Space Problem

Machine tool manufacturers face a constant challenge: customers want more capability in less space. As workpieces get smaller and precision requirements increase, every component needs to justify the room it occupies.

Traditional hydraulic power units haven’t kept pace with this miniaturization trend. A standard 4 kW unit typically requires 100 liters of oil capacity, a separate control cabinet, external cooling circuits, and enough clearance for maintenance access. That’s a lot of real estate for what’s essentially a support system.

Four Innovations That Changed Everything

Bosch Rexroth’s CytroPac takes a completely different approach—one that eliminates the traditional “installation space eaters” through intelligent integration:

1. Optimized Tank Design
By rethinking how oil degasses, engineers reduced tank volume by 80%—from 100 liters down to just 20 liters. That’s the same hydraulic performance in half the space.

2. Integrated Frequency Converter
The fully-wired frequency converter with multi-Ethernet interface lives inside the power unit itself. No separate control cabinet required. For many installations, that eliminates cabinet space entirely.

3. Heatpipe Cooling Technology
Instead of bulky cooling circuits, passive heatpipes transfer thermal energy from the motor, converter, and oil to a central cooling water connection. This cuts another layer of complexity and space consumption.

4. Built-in Condition Monitoring
Integrated sensors monitor fill level, temperature, pressure, and filter contamination—feeding data directly to Industry 4.0 systems through standard interfaces like Ethernet-IP, EtherCAT, and Profinet.

The Quiet Revolution: Noise Reduction Benefits

Manufacturing environments face increasing pressure to reduce workplace noise levels—both for operator comfort and regulatory compliance. Traditional hydraulic power units contribute significantly to ambient noise through pump operation, cooling fans, and pressure fluctuations during load changes.

CytroPac addresses this through multiple integrated design features. The variable-speed drive eliminates the constant high-RPM operation that characterizes fixed-speed systems—the pump only runs as fast as needed for current demand. Combined with optimized tank design that reduces fluid turbulence and heatpipe cooling that eliminates noisy cooling fans, overall sound emissions drop noticeably. Machine tool builders report quieter operation that improves the working environment without requiring additional sound insulation or enclosures.

Energy Efficiency That Pays Back

Energy costs represent a growing portion of manufacturing overhead, making hydraulic system efficiency more than an environmental consideration—it’s an economic one. Traditional fixed-speed hydraulic systems run at full capacity regardless of actual demand, wasting energy during idle periods and low-load operations.

CytroPac’s integrated frequency converter fundamentally changes this equation. The variable-speed drive adjusts pump speed continuously to match hydraulic demand, consuming energy proportional to actual work performed. This approach complies with EU Eco-Design Directive 2009/125/EC while delivering measurable cost savings. In typical machine tool duty cycles with significant idle time between operations, energy consumption can drop 30-50% compared to conventional fixed-speed units. For manufacturers running multiple machines across shifts, those savings compound quickly—turning energy efficiency from a compliance requirement into a competitive advantage.

Why Machine Tool Builders Are Rethinking Hydraulic Power Units

What This Means in Practice

The total footprint reduction? Up to 50% compared to conventional designs of equivalent performance.

But space savings aren’t the only benefit. Machine builders also gain:

  • Faster installation: Connect power, cooling water, data interface, and hydraulic supply—done
  • Reduced assembly errors: Everything’s pre-wired and tested at the factory
  • Lower total cost: Smaller footprint means smaller machine frame or larger work envelope
  • Future-ready connectivity: Condition monitoring enables predictive maintenance strategies

The Control Cabinet Question

Here’s where integration really pays off. When the frequency converter, sensor technology, and motor are all pre-wired within the power unit, many machine designs can eliminate the hydraulic control cabinet completely.

Even when cabinet space remains necessary for other systems, reducing its footprint by 100% for the hydraulic portion creates flexibility for other components or simply reduces the overall machine size.

A Different Design Philosophy

CytroPac represents a fundamental rethinking of what a hydraulic power unit should be. Rather than optimizing individual components and assembling them, the approach integrates everything from the start—designing for the complete system performance in minimum space.

This matters because machine tool economics increasingly favor compact, flexible designs. When manufacturers can offer the same machining capability in a smaller footprint, they win business. When they can integrate hydraulics without sacrificing valuable working space, they differentiate their products.

Beyond Just Smaller

Miniaturization alone wouldn’t justify redesigning a proven technology. But when you combine space savings with energy efficiency (variable-speed drives only consume what’s needed), simplified installation (plug-and-play connectivity), and Industry 4.0 readiness (integrated condition monitoring), the value proposition becomes compelling.

Machine tool builders working in the 4 kW performance range now have an alternative to the “bigger tank, bigger cabinet, bigger footprint” tradition.

Safety Solved: How STO Manifolds Deliver Critical Machine Protection Without the Engineering Headaches

Bosch Rexroth Web Editorial

When hydraulic system failures mean production stops, product gets damaged, or worse—people get hurt—you need more than components. You need solutions that work right out of the box.

Your Safety Challenge Just Got Simpler

Machine builders and plant operators face a persistent problem: meeting ISO 13849 functional safety requirements for hydraulic systems often means months of engineering, custom manifold design, complex safety assessments, and expensive validation. One miscalculation, and you’re back to square one.

The Bosch Rexroth STO (Safe Torque Off) Manifold eliminates this complexity entirely.

Problem Solved: Safety Functions That Work From Day One

The STOM series delivers pre-engineered, pre-validated safety shutdowns for hydraulic systems up to Category 4 PLe—the highest safety level defined by ISO 13849. Instead of designing your own safety circuits, you select from three standardized configurations based on four simple parameters:

  • Pressure (up to 315 bar)
  • Flow rate (up to 1750 l/min)
  • Required safety level (Cat 3 or Cat 4)
  • Functions needed (STO, SDE, SLS)

Your hydraulic problems—solved. From design constraints to uptime issues, we identify root causes and deliver effective hydraulic solutions.

Three Safety Functions in One Compact Block

Safe Torque Off (STO): Two-channel, position-monitored blocking from P1 to P2 ensures leak-free shutdown of entire machine areas or systems. When it must work—you call us.

Safe Decompression (SDE): Controlled pressure relief through dual bypass valves with flow-limiting nozzles safely drains downstream pressure in under 300ms in most applications. No sudden movements. No unexpected energy release.

Safe Limited Speed (SLS): Pre-compression through the same bypass circuit minimizes switching shocks, extends component life, and reduces noise—while meeting functional safety requirements for controlled flow.

The Engineering Time You’ll Save

Traditional custom safety manifolds require:

  • 40-80 hours of safety circuit design
  • Risk assessment documentation
  • Component selection and validation
  • Safety logic programming
  • Final system validation

With STOM, you select a material number from a datasheet. Documentation, validation calculations, and installation instructions are included. Every solution is engineered to simplify your machine lifecycle: Design → Installation → Operation → Maintenance.

Real-World Reliability From Decades of Expertise

The STOM portfolio builds on proven Bosch Rexroth valve technology—pilot-operated check valves (SL) in sizes 20/30, and actively controllable 2-way cartridge valves (LC2A) in sizes 32/40. These aren’t experimental components. They’re field-tested workhorses now configured for functional safety.

Galvanized surface coating provides long-term corrosion protection. Compatibility with mineral oils (HLP) and flame-resistant fluids (HFC, HFDU) means retrofit flexibility. Identical electrical control across all nominal sizes simplifies commissioning and spare parts management.
