The Bosch Rexroth TORQUE RESIST.BUSH KBDRC2-25 (R072032500) is a torqueresistant compact linear bushing that is engineered for self-supporting, torsionally stiff guides with only one shaft. This product is part of the Bosch Rexroth's series of torqueresistant compact linear bushings and falls under the product group ID Size N. It features ball guide grooves and is designed for use without a seal or shaft, providing flexibility for various applications. The TORQUE RESIST.BUSH KBDRC2-25 is distinguished by its ball retainer and outer sleeve made from durable PA or POM materials. It accommodates precision steel shafts with a ball guide groove, ensuring smooth motion and enhanced performance. The bushing's design includes hardened steel bearing plates and balls made from rolling bearing steel, which contribute to its robustness and longevity. This model has been set to zero clearance with an adjusting screw, ensuring precision in motion control tasks. A steel lock nut further secures the component in place. Its dynamic load capacity C and static load rating C0 are minimal values due to the potential variability in loading direction. The dynamic torsional moment load capacity Mt indicates its ability to withstand twisting forces during operation. The TORQUE RESIST.BUSH KBDRC2-25 operates within an ambient temperature range of -30°C to +80°C, can handle a maximum acceleration of amax, and supports a maximum permissible linear speed vmax. With its closed format, this linear bushing ensures streamlined motion control for various applications requiring high torsional rigidity. The unit's weight stands at 0.1 kg, making it a lightweight yet sturdy solution for linear motion needs.

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 .
