The Bosch Rexroth TORQUE RESIST.BUSH KBDRC2-25-WV-900 (R072032585) is a torqueresistant compact linear bushing that is designed to provide a self-supporting, torsionally stiff guide with only one shaft. This product is well-suited for applications that require precise linear movement with minimal clearance, as it includes an adjusting screw set to zero clearance. The bushing is equipped with ball guide grooves and comes with a precision steel shaft that facilitates smooth and accurate motion. Its construction features hardened steel bearing plates and balls made from rolling bearing steel, ensuring durability and long service life. The outer sleeve and ball retainer of this model are made from high-quality PA or POM materials, offering excellent strength and wear resistance. With a dynamic load capacity of C and a static load rating of C0, the KBDRC2-25-WV-900 can handle substantial loads while maintaining performance. It also boasts a dynamic torsional moment load capacity Mt, which makes it capable of withstanding rotational forces during operation. This linear bushing can operate within a temperature range of -30°C to +80°C, allowing for use in various environmental conditions without compromising its functionality. The maximum permissible linear speed vmax and the maximum acceleration amax highlight its capability to perform in high-speed applications while maintaining precision. With an outer diameter D and weight of 0.5 kg/m, it is compact yet robust enough for demanding applications. The Bosch Rexroth TORQUE RESIST.BUSH KBDRC2-25-WV-900 is part of the Torqueresistant compact product group within the Linear bushing and shaft series, reflecting its specialized design for high-performance linear guidance systems.

Reduced load capacity with short stroke

In case of short stroke, the service life of the shaft is less than that of the torque-resistant Linear Bushing. The dynamic load ratings C in the tables must therefore be multiplied by the factor fs .
