The Bosch Rexroth TORQUE RESIST.BUSH KBDR1-50 (R069605000) is a high-quality component designed for creating self-supporting, torsionally stiff guides with a single shaft application. This torque-resistant linear bushing comes without a seal and does not include a shaft, making it suitable for systems where these features are not required or are provided separately. The KBDR1-50 is equipped with hardened steel adjusting screws and steel lock nuts that allow for zero clearance adjustments, ensuring precise linear motion and reducing play within the mechanism. The outer sleeve and ball retainer of the KBDR1-50 are constructed from durable materials such as PA (Polyamide) or POM (Polyoxymethylene), providing excellent wear resistance and strength. The hardened steel bearing plates and balls made of rolling bearing steel contribute to the bushing's robustness and longevity. With ball guide grooves integrated into its design, this model ensures smooth, consistent motion along the guide shaft. The KBDR1-50 boasts impressive mechanical specifications, including a dynamic load capacity C that signifies minimal values due to variable loading directions. It can operate within an ambient temperature range of -30°C to +80°C, accommodating various working environments. Additionally, it has a maximum permissible linear speed (vmax) and can handle significant dynamic torsional moment load capacities (Mt), highlighting its capability to withstand high rotational forces. This linear bushing is part of the Torque Series Productgroup ID and comes in a closed format. Its size designation N indicates its compatibility with specific shaft diameters, while its weight reflects the solid construction without adding unnecessary bulk to the assembly. Ideal for applications requiring precise linear guidance with torsional rigidity, the Bosch Rexroth TORQUE RESIST.BUSH KBDR1-50 is engineered to deliver reliable performance in demanding situations.

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 .
