The Bosch Rexroth TORQUE RESIST.BUSH KBDR1-20 (R069602000) is a high-quality torqueresistant linear bushing designed to provide self-supporting, torsionally stiff guides in applications requiring only one shaft. This particular model is crafted without a seal and does not include a shaft. It features ball guide grooves for smooth motion and comes with an adjusting screw that has been pre-set to ensure zero clearance. The KBDR1-20 is constructed with a ball retainer and outer sleeve made of durable PA or POM materials, while the bearing plates are made of hardened steel, ensuring longevity and consistent performance. The balls themselves are crafted from rolling bearing steel, which contributes to the bushing's robustness and reliability. This linear bushing is capable of handling dynamic load capacities as well as static loads, with minimal values provided due to varying directions of loading that cannot always be clearly defined. It also boasts an impressive dynamic torsional moment load capacity, ensuring it can withstand the rigors of demanding applications. The product is suitable for use within a specified temperature range, maintaining functionality even in challenging environmental conditions. With its closed format design, the Bosch Rexroth KBDR1-20 ensures stability and precision in linear movements. The steel lock nut and hardened steel adjusting screw are integral components that contribute to the overall durability of this linear bushing. Its size N designation indicates its compatibility with certain dimensions required for specific applications. Overall, the Bosch Rexroth TORQUE RESIST.BUSH KBDR1-20 presents itself as an essential component for creating efficient and reliable linear motion systems where torsional stiffness is paramount. Its thoughtful engineering guarantees a balance between strength and precision, making it an ideal choice for various mechanical setups requiring high-performance guidance systems.

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 .
