The Bosch Rexroth TORQUE RESIST.BUSH KBDR4-F-30DD (R072523000) is a high-precision component designed for self-supporting, torsionally stiff linear guides with a single shaft. This torqueresistant linear bushing features a flanged version with four ball guide grooves that are essential for transferring torque, making it suitable for applications requiring precise rotational control. The bushing's shaft diameter is tailored to customer specifications, ensuring a perfect fit for the intended machinery. Equipped with integrated wiper seals, the KBDR4-F-30DD offers protection against contaminants, thereby enhancing the longevity and reliability of the bushing. The outer sleeve is hardened and ground to provide a durable and smooth surface for the ball retainer and balls which are made of rolling bearing steel. This construction ensures low friction and high wear resistance. The POM ball retainer within the bushing allows for smooth movement of the balls while maintaining their optimal distribution along the shaft. This feature contributes to the dynamic load capacity of the component, which supports minimal values as indicated by Bosch Rexroth due to variable loading directions that cannot always be clearly defined. Furthermore, this model is relubricatable, which simplifies maintenance procedures and extends service life. It can operate within a wide range of ambient temperatures and is capable of handling maximum acceleration as well as maximum permissible linear speed without compromise to its static torsional moment load capacity or dynamic torsional moment load capacity. The KBDR4-F-30DD's design aligns with Bosch Rexroth’s commitment to providing robust solutions for linear motion applications. Its compatibility with matching shaft profiles featuring machined ball guide grooves ensures seamless integration into diverse systems requiring precise torque resistance and guidance. The weight specification indicates that it adds minimal mass to an assembly, thus maintaining efficiency in machine design.
