The Bosch Rexroth TORQUE RESIST.BUSH KBDR4-H-20DD (R072422000) is a high-performance torqueresistant linear bushing designed for self-supporting, torsionally stiff guides with a single shaft. This cylindrical sleeve design integrates four ball guide grooves that are essential for transferring torque effectively. The KBDR4-H-20DD is engineered to work with matching shaft profiles that have machined ball guide grooves, and these shafts are tailored according to customer specifications. The linear bushing features an outer sleeve that is both hardened and ground for durability, while the POM ball retainer and balls made of rolling bearing steel ensure smooth motion and high load capacity. It also includes integrated wiper seals to maintain cleanliness within the system and comes equipped with a fitting key for reliable torque transmission. This model is relubricatable, which allows for easy maintenance and extended service life. With its dynamic load capacity C and static load rating C, the KBDR4-H-20DD can handle minimal values as specified since the direction of loading might not always be clearly defined. The permissible ambient temperature range in which this bushing operates effectively is from -20°C to +80°C, ensuring reliable performance in various working conditions. The maximum permissible linear speed (vmax) and static torsional moment load capacity (Mt) further define its capabilities in demanding applications. The size L specification denotes the bushing's physical dimensions, while the weight indicates its heft which contributes to overall system stability. This linear bushing is part of Bosch Rexroth's Torque Productgroup ID series, highlighting its specialized function in torque-sensitive applications. In summary, the Bosch Rexroth TORQUE RESIST.BUSH KBDR4-H-20DD offers precise guidance with high torque transmission capabilities suitable for various industrial applications requiring robust linear movement solutions. Its design emphasizes performance, longevity, and ease of maintenance making it a valuable component in sophisticated mechanical systems.
