The Bosch Rexroth TORQUE RESIST.BUSH KBDR4-H-10DD (R072421000) is a high-precision, torqueresistant linear bushing designed to provide reliable guidance and support in applications requiring torsionally stiff guides with only one shaft. This cylindrical sleeve design is equipped with four ball guide grooves, which are essential for transferring torque efficiently. The model is particularly suitable for self-supporting structures and can be used in conjunction with matching shaft profiles that have machined ball guide grooves tailored to customer specifications. The KBDR4-H-10DD features an integrated wiper seal system that ensures long-term protection against contamination, thereby extending the product's service life. The outer sleeve of the bushing is hardened and ground for enhanced durability, while the POM ball retainer and balls made of rolling bearing steel ensure smooth motion and high load capacities. For secure installation, a fitting key is provided for effective torque transmission. Maintenance is simplified thanks to the relubricatable design of this model, allowing for easy servicing and extended operational life. The dynamic load capacity C and static load rating C are indicative of minimal values due to varying loading directions that cannot always be clearly defined in applications. Additionally, the dynamic torsional moment load capacity Mt and static torsional moment load capacity Mt offer robust performance under various operating conditions. This linear bushing can operate within a wide range of ambient temperatures and is capable of handling maximum accelerations as well as high linear speeds without compromising its structural integrity or performance. Its precise engineering makes it an ideal choice for sophisticated linear motion tasks where torque resistance is critical. The weight and size L specifications reflect Bosch Rexroth's commitment to producing compact yet powerful components suitable for a variety of industrial applications.
