The Bosch Rexroth TORQUE RESIST.BUSH KBDRC2-25-WV-2000 (R072032588) is a high-quality, torque-resistant compact linear bushing designed for self-supporting, torsionally stiff guides with only one shaft. This precision component features ball guide grooves and comes with a standard length shaft that has been machined to accommodate these grooves. It is specifically crafted for applications requiring a robust linear motion solution where the direction of force cannot always be clearly defined. The KBDRC2-25-WV-2000 is equipped with hardened steel bearing plates and balls made from rolling bearing steel, ensuring durability and smooth operation. The adjusting screw made of hardened steel allows for zero-clearance setting, while the steel lock nut secures adjustments in place. The ball retainer and outer sleeve are constructed from PA or POM, materials known for their strength and stability. With a dynamic load capacity (C) and static load rating (Co), this linear bushing can handle significant loads while maintaining precision movement. Its dynamic torsional moment load capacity (Mt) further attests to its ability to withstand twisting forces during operation. The product operates efficiently within an ambient temperature range of -30°C to +80°C, making it suitable for various environments. The outer diameter (D), maximum permissible linear speed (vmax), mass (m kg/m), along with the dynamic load capacity, all contribute to its capability to perform in demanding applications. The linear guide type is a closed format which enhances the overall system rigidity. Overall, the Bosch Rexroth TORQUE RESIST.BUSH KBDRC2-25-WV-2000 offers a reliable and precise solution for linear motion requirements in applications where both axial and torsional loads are present. With its robust construction and precision engineering, it ensures consistent performance and longevity in industrial settings.

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 .
