The Bosch Rexroth TORQUE RESIST.BUSH KBDR4-H-16DD (R072421600) is a high-quality, torque-resistant linear bushing designed for self-supporting, torsionally stiff guides that utilize a single shaft. This cylindrical sleeve design features four ball guide grooves that are essential for transferring torque and are compatible with matching shaft profiles that have machined ball guide grooves tailored to customer specifications. The KBDR4-H-16DD is equipped with integrated wiper seals to maintain cleanliness and protect the internal components, ensuring durability and longevity. The outer sleeve of the bushing is hardened and ground for precision, while the POM ball retainer and balls made of rolling bearing steel provide smooth movement. A fitting key is included for efficient torque transmission, and the unit is relubricatable to allow for easy maintenance. This model has been engineered to withstand dynamic load capacities as well as static and dynamic torsional moment load capacities, although these values are minimal due to variable loading directions. With a permissible ambient temperature range from -30°C to +80°C, this linear bushing can operate effectively in diverse environments. It also supports maximum acceleration and linear speeds without compromising performance. The static torsional moment load capacity Mt ensures stability under loads, while the size L denotes its compact form factor suitable for various applications. Lastly, this model's weight is optimized for its size and function without sacrificing strength or functionality. The Bosch Rexroth KBDR4-H-16DD linear bushing represents a reliable solution for precise linear motion applications where torque resistance is crucial.
