Maximizing uptime in factory automation requires sourcing highly reliable mechanical components. Bosch Rexroth Linear Motion Technology offers an extensive portfolio of precision products designed to handle heavy loads, extreme speeds, and strict accuracy requirements.
This guide reviews the specific Bosch Rexroth linear motion products, product codes, and modular systems available to upgrade your industrial machinery.
Profiled Rail Systems: Linear Guides and Runner Blocks
Bosch Rexroth manufactures a wide array of linear guide products designed with an interchangeable format. This means any runner block can fit onto any guide rail of the same size, simplifying inventory management.
Bosch Rexroth Ball Rail Systems (BRS)
These products are the industry standard for general automation, offering high load capacities in all four directions of load application.
- Standard Ball Runner Blocks: Available in flanged (FLS, FNS), slim line (SNS, SLS), and compact designs.
- Ball Guide Rails: Feature options with or without cover strips, plus specialized coatings like Resist CR (chrome-plated) for corrosion resistance.
- High-Speed Variants: Designed for high dynamic performance up to 10 m/s.
Bosch Rexroth Roller Rail Systems (RRS)
When your machinery demands extreme rigidity and heavy-duty load capacities, roller-based products outperform ball bearings.
- Roller Runner Blocks: Available in standard steel, heavy-duty (FXS, RXS), and wide designs to handle massive torque.
- Roller Guide Rails: Engineered for machine tools, injection molding, and heavy industrial automation.
Bosch Rexroth Miniature Ball Rail Systems (MBR)
For the medical, laboratory, and semiconductor industries, these ultra-compact products offer high precision in confined spaces.
Linear Drive Products: High-Precision Screw Drives
Converting rotary motor power into precise linear translation requires efficient, low-friction screw products.
- Bosch Rexroth Ball Screw Assemblies (BSHP): These high-precision products feature internal recirculation loops, offering quiet operation, smooth travel, and an extended service life.
- Bosch Rexroth Planetary Screw Drives (PLSA): Built for high axial load applications, these products are the ideal mechanical replacement for hydraulic cylinders.
Ready-to-Install Linear Modules and Subsystems
For engineering teams looking to reduce assembly times, Bosch Rexroth provides pre-assembled, multi-axis linear system products.
