The Bosch Rexroth TORQUE RESIST.BUSH KBDR4-LR-30DD (R072723000) is a high-quality torque-resistant linear bushing designed for self-supporting, torsionally stiff guides with a single shaft. This particular model incorporates four ball guide grooves that enable the transfer of torque, making it suitable for applications requiring precise linear movement combined with rotational motion. The KBDR4-LR-30DD features an integrated crossroller bearing that comes pre-lubricated, ensuring smooth operation and reducing maintenance requirements. The outer sleeve of the bushing is hardened and ground for durability, while the POM ball retainer and balls made of rolling bearing steel contribute to the unit's robust performance. The design includes integrated wiper seals to protect against contamination, extending the life of the bushing. With a shaft diameter detailed as size 'd', this linear bushing can accommodate matching shaft profiles that are machined according to customer specifications. Capable of handling dynamic load capacities and static load ratings that are specified as minimal values due to variable loading orientations and directions, this model also has defined dynamic torsional moment load capacity Mt and tightening torque values. It operates effectively within a permissible ambient temperature range, ensuring reliability across different working environments. The maximum acceleration (amax), limit speed for grease (nmax), and maximum permissible linear speed (vmax) are specified to guide optimal usage conditions. Overall, the Bosch Rexroth KBDR4-LR-30DD is part of a product group known for its precision in linear motion systems. It weighs in at a specific value, indicating its suitability for various design specifications where weight considerations are crucial. Its construction reflects Bosch Rexroth's commitment to engineering excellence in providing components for sophisticated mechanical systems.
