The Bosch Rexroth FLANGE LIN.BUSHING KBMM-20-DD-NR (R074222030) is a high-quality component designed for precision linear motion applications. This central flanged linear bushing features a rugged all-metal design, with a steel ball retainer that makes it suitable for use in harsh environments and heavy contamination areas such as woodworking, foundries, and cement plants. Its stainless steel construction also allows for applications within the medical, chemistry, and food industries where rust resistance is crucial. The KBMM-20-DD-NR is engineered to provide smooth motion with its hardened and machined outer sleeve, ball retainer, balls, and flange—all made of stainless steel comparable to . This ensures durability and reliability even in demanding conditions. The bushing comes equipped with two integrated wiper seals that help prevent dirt from entering the mechanism, thus protecting against jamming and extending the service life of the bushing. Additionally, the design includes many pockets that act as lubricant reservoirs which can either prolong lubrication intervals or support lubrication for life. With a shaft diameter 'd' size V and rows of balls configuration, this linear bushing offers excellent load capacities—both dynamic (Cmin and Cmax) and static (Cmin and Cmax)—and is capable of withstanding significant forces while maintaining precision. It has been designed to accommodate permissible ambient temperatures ranging from C to C for sealed versions; however, unsealed versions may be used at higher temperatures with appropriate load capacity adjustments. The Bosch Rexroth FLANGE LIN.BUSHING KBMM-20-DD-NR also features a maximum acceleration amax detail, breakaway force specification, maximum permissible linear speed vmax detail, along with static longitudinal moment load capacity ML for size L. Weighing in at . kg, this linear bushing represents an efficient solution for various industrial motion tasks requiring both precision and robustness in challenging environments.
