✉ Inquire Now: thk@591888888.comBosch Rexroth AG, headquartered in Lohr am Main, Germany, is a global leader in drive and control technologies with annual revenue exceeding EUR 7 billion. The Linear Motion Technology division produces some of the most robust and reliable profiled rail systems in the world — engineered for heavy industrial environments where failure is not an option.
Rexroth's Ball Rail Systems and Roller Rail Systems are the go-to choice for wind turbine pitch control, large-scale CNC machine tools, heavy material handling, and steel mill automation. With dynamic load ratings extending to over 800 kN in roller configurations and a full ecosystem of drives, motors, and controllers, Rexroth delivers end-to-end linear motion solutions.
Profiled rail systems with four-row ball circulation. Available in sizes 15-65 with flange, slim, and high-profile carriage designs. All-direction equal load capacity.
Applications: General automation, packaging, material handling
Heavy-duty roller rail systems with two-row cylindrical roller circulation. Dynamic load capacity up to 800+ kN. Designed for extreme rigidity and impact resistance.
Applications: Heavy machine tools, injection molding, press transfer, wind power
German-standard DIN 69051 ball screws in accuracy classes T3-T10. Single and double nut configurations with flange or cylindrical mounting options.
Applications: CNC axes, gantry drives, pressing and forming equipment
Ready-to-mount linear motion modules integrating ball rail guide, ball screw or toothed belt drive, and motor adapter. IP65 sealed versions available.
Applications: Handling, gantry systems, assembly automation, welding cells

Rexroth R1845/R1853 roller rail systems for blade pitch adjustment and nacelle yaw drives. High corrosion resistance (Resist NR II coating) for offshore wind farms. Lifetime-lubricated carriages rated for 20+ year service.
R1865/R1875 heavy roller rails with integrated measuring systems for gantry milling machines and vertical turning lathes. Maintains 10 µm positioning accuracy under 300+ kN cutting forces.
R1851 ball rails and R1845 roller rails for mold clamping and ejector mechanisms. Designed for millions of cycles with minimal maintenance in high-temperature, high-pressure environments.
R1865 roller rail systems for slab handling, coil transfer cars, and furnace charging machines. High resistance to scale, dust, and thermal shock with reinforced double-lip seals.
Bosch Rexroth and THK can be cross-evaluated in heavy-duty industrial applications. The Rexroth R1845 roller rail series competes directly with THK's SNR/SNS roller guides — both offer dynamic load ratings above 300 kN. Rexroth's integrated drive ecosystem (IndraDrive + MSK motors) provides a single-supplier advantage for complete axis solutions. For standard automation, Rexroth R1605 and HIWIN HG series share similar dimensional envelopes in many sizes.
Ball Rail Systems (R1605 etc.) use four rows of recirculating balls, providing equal load capacity in all loading directions and low friction. Roller Rail Systems (R1845 etc.) use two rows of cylindrical rollers, delivering 2-3× higher static and dynamic load capacity, superior rigidity, and better vibration damping — ideal for heavy cutting, impact loads, and large machine structures.
Yes. Rexroth is unique in offering fully integrated linear axes: guide rails + ball/roller screw + servo motor (MSK/IndraDyn series) + drive controller (IndraDrive) + cables — all from a single manufacturer. This simplifies procurement, ensures compatibility, and provides a single point of warranty.
Rexroth offers Resist CR (hard chrome plating, standard), Resist M (electroless nickel, moderate corrosion), and Resist NR II (CrN PVD coating, maximum corrosion resistance for offshore and chemical environments). Stainless steel carriages are available as a factory option.
Our engineering team uses the Rexroth Linear Motion e-tool for sizing. Provide the applied loads (Fx, Fy, Fz, moments), stroke length, acceleration profile, and desired service life (hours or km). We calculate the static safety factor and dynamic life rating for each candidate rail/carriage combination and return a shortlist with pricing. Email thk@591888888.com to start.
