The Bosch Rexroth TORQUE RESIST.BUSH KBDR4-H-8DD (R072420800) is a robust, torqueresistant linear bushing designed to provide a self-supporting, torsionally stiff guide in applications requiring the transfer of torque along with linear motion. This cylindrical, sleeve-design bushing features four ball guide grooves that are essential for transmitting torque and are compatible with matching shaft profiles that have machined ball guide grooves. The shaft diameter is detailed and tailored according to customer specifications. Constructed with an outer sleeve that is hardened and ground, the KBDR4-H-8DD ensures durability and precision. The POM ball retainer within the bushing holds balls made of rolling bearing steel, which are known for their high strength and wear resistance. Integrated wiper seals are included to maintain cleanliness within the bushing by preventing contamination from external sources. This linear bushing stands out for its ability to be relubricated, extending its service life under varying operational conditions. It also comes with a fitting key for reliable torque transmission. The dynamic load capacity C and static load rating C indicate minimal values due to the complexity in defining the direction of loading precisely. The KBDR4-H-8DD can operate within a wide range of ambient temperatures and is capable of handling maximum acceleration as well as high linear speeds without compromising performance. It has been designed to withstand a significant static torsional moment load capacity Mt, ensuring stability under torsional stresses. With its size L tailored to specific applications, this linear bushing from Bosch Rexroth is suitable for use in environments where precise linear movement with simultaneous torque transmission is required. Its construction quality and design features make it an ideal choice for sophisticated mechanical systems requiring reliable linear guidance with torque-resistance capabilities.
