The Bosch Rexroth FLANGE LIN.BUSHING KBMM-30-DD (R074253000) is a robust and durable central flanged linear bushing designed for use in demanding environments such as woodworking, foundries, and cement plants. It features a rugged all-metal design with a hardened and ground outer sleeve, ensuring it can withstand harsh conditions and heavy contamination. The steel ball retainer within this bushing provides stability and smooth motion even in the presence of dirt and debris, thanks to the many pockets that act as lubricant reservoirs. These pockets also serve to collect any particulates that may enter the bushing, preventing jamming. This model comes equipped with integrated wiper seals on both sides that help maintain cleanliness within the system while contributing to frictional drag when not under radial load. The balls are made from rolling bearing steel, which enhances durability and performance. The FLANGE LIN.BUSHING KBMM-30-DD is designed for a shaft diameter of 'd' and has an outer diameter 'D'. It boasts a maximum dynamic load capacity (Cmax) based on total travel distance, with specific multipliers provided for different travel lengths. The product's design allows for extended lubrication intervals or even lubrication for life under certain conditions. The permissible ambient temperature range ensures reliable operation within specified thermal limits, although higher temperatures are only recommended for linear bushings without wiper seals. Additionally, details such as minimum and maximum static load capacities (Cmin and Cmax), dynamic load capacity (Cmin), breakaway force, maximum permissible linear speed (vmax), weight, size specifications (V & L), static longitudinal moment load capacity (ML), and friction force are all meticulously defined to ensure proper selection for specific applications. Overall, the Bosch Rexroth FLANGE LIN.BUSHING KBMM-30-DD offers exceptional performance in environments where reliability under tough conditions is paramount. Its design facilitates maintenance-free operation over extended periods, making it an ideal choice for heavy-duty industrial applications requiring precise linear motion control.
