The Bosch Rexroth FLANGE LIN.BUSHING KBMM-8-DD (R074250800) is a robust flange linear bushing designed for high durability and performance in demanding environments. This standard metal central flanged bushing is engineered with a hardened and ground outer sleeve, which ensures its reliability in heavy contamination settings such as woodworking, foundries, and cement plants. It features a POM ball retainer and balls made from rolling bearing steel that contribute to its sturdy construction. The KBMM-8-DD has an integrated wiper seal on both sides to prevent dirt ingress and jamming, thus extending the life of the bushing. The numerous pockets within the design act as lubricant reservoirs, allowing for extended lubrication intervals or even lifetime lubrication. Its size V structure accommodates a shaft diameter (d), and it's equipped with two seals for added protection against contaminants. This model boasts a maximum dynamic load capacity (Cmax) and minimum dynamic load capacity (Cmin), which are determined based on a total travel distance of 100,000 m. For applications based on 50,000 m travel distance, these capacities can be adjusted by multiplying with specific factors provided in the product specifications. The FLANGE LIN.BUSHING KBMM-8-DD also has specified static load capacities (minimum Cmin and maximum Cmax) along with a static longitudinal moment load capacity (ML). With its rugged all-metal design featuring steel ball retainers, this linear bushing can withstand high acceleration (amax) and operate within a permissible ambient temperature range. The product's friction force is noted under non-radial loads and varies depending on speed and lubrication conditions. Overall, the Bosch Rexroth FLANGE LIN.BUSHING KBMM-8-DD offers exceptional load handling capabilities suitable for linear motion applications where durability and reliability are critical under harsh conditions.
