  • Torque-Resistant Linear Bushings (LBTR) — designed to prevent rotation of the carriage, ideal for single-shaft configurations where rotational restraint is required
  • Compact and Radial variants — for space-constrained designs and non-standard mounting configurations

Precision steel shafts, shaft support rails, shaft support blocks, and complete linear sets are available to complement the bushing range, enabling fully engineered round shaft linear systems to be assembled from standard components.

Linear Motion Systems — Modules, Axes, and Mechatronic Solutions

Beyond individual components, Bosch Rexroth offers a complete range of ready-to-install linear motion systems that combine guidance, drive, and control elements into pre-engineered, pre-assembled solutions.

Linear Modules

Compact, economical, ready-to-install linear motion systems incorporating ball rail guidance and ball screw or toothed belt drive. Linear Modules are designed for fast integration into automation systems, reducing design time and commissioning effort while delivering reliable, repeatable positioning performance.

Compact Modules

Precision, high-performance linear motion systems incorporating an extremely compact steel frame with precision ball screw drive. Compact Modules offer high load capacities, high rigidity, and zero-backlash nut systems for superior positioning accuracy and repeatability — in a form factor suitable for integration into space-constrained machine designs.

Omega Modules

Ball rail systems combined with a toothed belt drive for high-speed linear motion applications. Omega Modules support travel speeds up to 5.0 m/s, making them the solution of choice where rapid traverse rates are required alongside precise guidance.

Precision Modules (PSK)

Ready-to-install precision linear motion systems combining high performance with compact dimensions — suited to applications requiring consistent positioning accuracy over extended service life.

Ball Rail Tables (TKK)

Precision guidance systems with high performance characteristics and compact dimensions, designed for use as complete positioning tables in machining and assembly applications.

Cartesian Multi-Axis Systems

For applications requiring coordinated motion across multiple axes, Bosch Rexroth offers pre-configured Cartesian multi-axis systems combining best-in-class linear motion components with automation hardware, cable management, and control systems in a single, co-ordinated package. These systems significantly reduce engineering effort and commissioning time for gantry, handling, and pick-and-place applications.

Integrated Measuring Systems (IMS)

One of the most significant recent innovations in the Bosch Rexroth linear motion range is the Integrated Measuring System (IMS). Fully integrated into the runner block or carriage, the IMS uses a magnetic measuring principle to provide precise, reliable position feedback — comparable in accuracy to glass scales but without the sensitivity to dirt, vibration, or shock that limits traditional external measuring systems.

The IMS is available in both incremental and absolute variants and is fully compatible with Rexroth linear motion components including ball rail systems and linear motors. For machine builders working in demanding environments or seeking to reduce system complexity, the IMS offers a compelling alternative to conventional external encoders and scales.

Frequently Asked Questions — Bosch Rexroth Linear Motion

Can I mix Bosch Rexroth rails and runner blocks with other brands? Bosch Rexroth profiled rail systems are designed to be interchangeable within Rexroth’s own product range,  rails and runner blocks of the same size and accuracy class can be combined freely. However, Rexroth components are not designed to be interchangeable with other manufacturers’ rails or runner blocks. For replacement or upgrade projects involving mixed-brand systems, our technical team can advise on the best approach.

What accuracy classes are available in the Bosch Rexroth Ball Rail System? Rexroth Ball Rail Systems are available in multiple accuracy classes to suit applications from general automation through to high-precision machine tool guidance. The appropriate class for your application depends on your positional tolerance requirements and the nature of the loads involved. Contact the Linear Technik team for guidance on accuracy class selection.

Does Bosch Rexroth offer corrosion-resistant linear motion components? Yes. The Rexroth range includes Resist CR variants of both ball rail and roller rail systems, manufactured from rust and acid-resistant stainless steel materials. These are designed for applications in food processing, pharmaceutical manufacturing, washdown environments, and other settings where corrosion resistance is essential.

What is the difference between Ball Rail and Roller Rail systems? Ball Rail Systems use recirculating balls as the rolling elements, offering a good balance of load capacity, speed, accuracy, and cost. Roller Rail Systems use cylindrical rollers, which provide significantly higher rigidity, load capacity, and moment resistance — but at a higher cost and typically lower maximum speed. The right choice depends on your application’s load, rigidity, speed, and budget requirements.

Can Linear Technik supply complete Bosch Rexroth linear axes and systems, not just components? Yes. Linear Technik supplies the full Bosch Rexroth linear motion range including ready-to-install Linear Modules, Compact Modules, Omega Modules, and Cartesian multi-axis systems — not just individual rails, runner blocks, and screws.

What is the Bosch Rexroth Integrated Measuring System (IMS)? The IMS is a position measuring system fully integrated into the Rexroth runner block or carriage. It uses a magnetic measuring principle to provide precise position feedback without the need for a separate external encoder or scale — offering accuracy comparable to glass scales but with superior resistance to contamination, vibration, and shock. Available in incremental and absolute variants.
