The Bosch Rexroth TORQUE RESIST.BUSH KBDR1-12-WV-900 (R069601285) is a high-quality, torqueresistant linear bushing designed for self-supporting, torsionally stiff guides with only one shaft. This model is engineered without a seal and includes a precision steel shaft with a standard length that adheres to specified tables. The shaft features one ball guide groove which is essential for transferring torques effectively. The KBDR1-12-WV-900 is constructed with ball retainer and outer sleeve made from either PA or POM, while the bearing plates are crafted from hardened steel to ensure durability and longevity. The balls within the bushing are made from rolling bearing steel, which is known for its strength and resistance to wear. Additionally, this model comes equipped with a hardened steel adjusting screw and a robust steel lock nut, allowing for precise adjustments and secure fastening. This linear bushing boasts an impressive dynamic load capacity C and static load rating C which are minimal values due to the variable directions of loading that cannot always be definitively determined. It can operate within a wide temperature range, maintaining performance in varying environmental conditions. The maximum permissible linear speed vmax and mass m kg/m are specified to provide clear guidelines for its operational capabilities. Designed as part of the Torque Productgroup ID series, the KBDR1-12-WV-900 also features an outer diameter D that complies with system requirements. Its dynamic torsional moment load capacity Mt further demonstrates its ability to handle significant loads during operation. As a closed format linear bushing, this product ensures smooth motion control in applications requiring precise torque resistance and guidance.

1) The load ratings indicated are minimal values as the load direction cannot always be clearly defined.
The load ratings are based on a total travel of 100, 00 m. When based on 50 000 m, the  values in the table need to be multiplied by 1.26.

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 .

Initial lubrication

Linear bushings do not come with initial lubrication. Grease the Linear Bushings before use. Service life data is based on initial lubrication and relubricated Linear Bushings.
