The Bosch Rexroth TORQUE RESIST.BUSH KBDR4-LR-25DD (R072722500) is a torqueresistant linear bushing designed to provide self-supporting, torsionally stiff guides with only one shaft. It features an integrated crossroller bearing for high precision and initial lubrication for immediate use. The outer sleeve is hardened and ground to ensure durability, while the POM ball retainer and balls made of rolling bearing steel enable smooth motion. This model includes four ball guide grooves that are essential for transferring torque effectively. The KBDR4-LR-25DD is equipped with two seals to protect against contaminants and extend the lifespan of the component. Shafts can be machined to customer specifications, which allows for a custom fit in various applications. This bushing is capable of withstanding dynamic load capacities as well as static loads, though these values are minimal due to potential variations in loading orientation and direction. With a permissible ambient temperature range from -20°C to 80°C, this linear bushing can operate effectively in diverse environments. The maximum permissible linear speed (vmax) and limit speed for grease (nmax) are indicative of its capability to handle high-speed operations without compromising performance. In terms of physical dimensions, the Size L indicates the length of the bushing, which contributes to its overall weight of 0.45 kg. The dynamic torsional moment load capacity (Mt) reflects its ability to resist twisting forces during operation. This Bosch Rexroth linear bushing is part of a product group designed for applications requiring precise linear movement with torque resistance. It's particularly suitable for single-shaft configurations where rigidity and accurate motion control are critical. Whether used in automation or machine design, this component ensures reliable performance under challenging conditions.
