The Bosch Rexroth TORQUE RESIST.BUSH KBDR2-25 (R069632500) is a high-performance component designed for self-supporting, torsionally stiff guides with a single shaft application. This torque-resistant linear bushing is crafted without a seal and does not include a shaft, emphasizing its suitability for systems where these features are not required or are provided separately. The bushing incorporates ball guide grooves and is equipped with a hardened steel adjusting screw and steel lock nut, allowing for precise adjustment to zero clearance. Constructed with a ball retainer and outer sleeve made from durable PA or POM materials, the KBDR2-25 ensures reliable operation within its specified applications. The hardened steel bearing plates and balls made of rolling bearing steel contribute to the bushing's robustness and longevity. Its design is optimized for dynamic load capacity, with minimal values provided due to the variable nature of loading directions. The dynamic torsional moment load capacity Mt of this model demonstrates its capability to withstand rotational forces during operation. As a closed format linear bushing, it offers protection against contaminants while maintaining its performance characteristics. The size N static load rating C and dynamic load capacity C are indicative of the bushing's ability to handle substantial loads. With an operating temperature range from -30°C to +80°C, the KBDR2-25 can function effectively in various environmental conditions. Its maximum permissible linear speed vmax ensures swift motion within mechanical assemblies without compromising stability or performance. The weight of 0.1 kg makes it relatively lightweight, allowing for easy integration without adding significant mass to the assembly. Overall, the Bosch Rexroth TORQUE RESIST.BUSH KBDR2-25 (R069632500) is engineered for precision, durability, and reliability in demanding linear motion applications where torsional resistance is crucial.

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 .
