The Bosch Rexroth FLANGE LIN.BUSHING KBMF-40-DD (R074054000) is a high-quality flange linear bushing designed for robust and precise linear motion applications. This standard metal flange bushing features a hardened and ground outer sleeve, which ensures durability and consistent performance even in harsh environments such as woodworking, foundries, and cement plants. It is equipped with steel ball retainers that can withstand heavy contamination and provide extended lubrication intervals or even lubrication for life. The KBMF-40-DD bushing has a shaft diameter of 40mm and incorporates two integrated wiper seals to prevent the ingress of dirt, protecting the internal components from jamming. Additionally, multiple lubricant reservoirs are strategically placed to collect any contaminants that may enter the system. The POM ball retainer within the bushing ensures smooth movement of the rolling bearing steel balls, delivering precise linear guidance. This bushing is capable of handling maximum dynamic load capacities (Cmax) with specific values determined based on total travel distance, ensuring reliable operation over extensive periods. It also has defined minimum static (Cmin) and maximum static load capacities (Cmax), which are essential for various static and dynamic applications. The KBMF-40-DD operates efficiently within a permissible ambient temperature range from -20°C to +80°C, although higher temperatures are possible with certain restrictions. Moreover, it can sustain maximum accelerations (amax) without compromising its structural integrity or performance. With a size designation of V1 for its rows of balls and an outer diameter D1, this flange linear bushing offers a breakaway force parameter that ensures reliability upon initial movement. Its friction force is also noted under no radial load conditions, indicating the smoothness of operation at different speeds and lubrication statuses. Overall, the Bosch Rexroth FLANGE LIN.BUSHING KBMF-40-DD provides an effective solution for linear motion requirements in demanding industrial settings with its rugged construction, integrated sealing technology, and maintenance-friendly design.
