The Bosch Rexroth TORQUE RESIST.BUSH KBDR4-LR-20DD (R072722000) is a state-of-the-art linear bushing designed for self-supporting, torsionally stiff guides with a single shaft. This advanced component features four ball guide grooves that are essential for transferring torque efficiently. The KBDR4-LR-20DD is specifically crafted to work with matching shaft profiles that have machined ball guide grooves, tailored to customer specifications. The bushing incorporates an integrated crossroller bearing that benefits from initial lubrication, contributing to its smooth operation and longevity. The outer sleeve of the bushing is both hardened and ground to ensure durability and precise movement. The POM ball retainer within the bushing holds balls made of rolling bearing steel, which provides a robust and reliable performance. In addition to its mechanical capabilities, the KBDR4-LR-20DD includes integrated wiper seals that help maintain cleanliness and protect internal components from contaminants. This feature also aids in preserving the dynamic load capacity of the bushing over time. The technical specifications of this model include a dynamic torsional moment load capacity (Mt), static load rating (C0), and dynamic load capacity (C). These capacities indicate minimal values due to varying orientations and directions of loading in different applications. For optimal performance, it adheres to specific permissible ambient temperature ranges and has defined limits for speed in terms of maximum acceleration (amax), limit speed with grease (nmax), and maximum permissible linear speed (vmax). The tightening torque is also specified for secure installation. With a size L dimension provided by Bosch Rexroth, this linear bushing model is part of their comprehensive product group ID designed for high precision applications requiring torque resistance. The weight details are provided ensuring users can account for this in their design specifications. Overall, the Bosch Rexroth TORQUE RESIST.BUSH KBDR4-LR-20DD offers exceptional functionality for sophisticated linear motion tasks where high torque capacity and precision are required.
