The Bosch Rexroth FLANGE LIN.BUSHING KBMM-40-DD (R074254000) is a flange linear bushing designed for high-load and harsh-environment applications. This robust component features a standard metal, central flanged design that is suitable for woodworking, foundries, and cement plants due to its rugged all-metal construction with a steel ball retainer. It offers enhanced durability and performance in environments with heavy contamination. With a shaft diameter of 40mm, this linear bushing includes two integrated wiper seals that protect against dirt ingress and maintain smooth operation by acting as lubricant reservoirs. These features contribute to extended lubrication intervals or potentially lubrication-free service life. The bushing's outer sleeve is hardened and ground for precision, while the POM ball retainer ensures stable movement of the rolling bearing steel balls within. The KBMM-40-DD is engineered to handle dynamic loads efficiently with its maximum dynamic load capacity Cmax and minimum dynamic load capacity Cmin based on total travel distances of 100,000m and 50,000m respectively. For static loads, the minimum static load capacity Cmin and maximum static load capacity Cmax provide an indication of the bushing's strength when stationary. This linear guide type bushing can withstand accelerations up to its specified amax value and operates effectively within a permissible ambient temperature range. The integration of multiple rows of balls ensures consistent performance under radial loads, while the breakaway force indicates the initial resistance to motion. Weighing in at 0.5kg, the KBMM-40-DD offers a balance between strength and weight efficiency for various linear motion applications. Its design also includes many pockets that serve as dirt collection points to prevent jamming, ensuring reliability even in demanding operational conditions.
