The Bosch Rexroth FLANGE LIN.BUSHING KBMFT-20-DD (R074152000) is a flange linear bushing designed for high-load, high-precision linear motion applications. This robust component is part of the standard metal series with a flanged, tandem configuration, specifically engineered to thrive in harsh environments and heavy contamination such as woodworking shops, foundries, and cement plants. Its rugged all-metal design incorporates many pockets that act as lubricant reservoirs to extend lubrication intervals or even allow for lubrication-free operation. The KBMFT-20-DD features an integrated wiper seal system that not only retains the lubricant but also prevents dirt from entering and jamming the bushing. The hardened and ground outer sleeve ensures durability while the POM ball retainer and balls made of rolling bearing steel facilitate smooth motion. The unit has been designed for a shaft diameter 'd' and offers standard radial clearance 'h', which is determined from working bore diameter and shaft tolerance statistics. This model also includes important specifications related to load capacity and environmental conditions. It has a maximum dynamic load capacity (Cmax) and minimum dynamic load capacity (Cmin), both calculated based on a total travel of 100 km, with adjustments provided for different travel distances. The permissible ambient temperature range for operation is specified, with higher temperatures being admissible only at linear bushings without wiper seals. Other technical details include maximum acceleration (amax), outer diameter (D), breakaway force, maximum permissible linear speed (vmax), friction force, static load capacities (both minimum Cmin and maximum Cmax), as well as static longitudinal moment load capacity (ML). These specifications are crucial for designers to ensure compatibility with the intended application's requirements. With its size 'V' and weight of 0.2 kg, this linear bushing is identified under Productgroup ID FT – Flanged Tandem – making it an essential component in precision linear motion systems where reliability under tough conditions is paramount.
