The Bosch Rexroth FLANGE LIN.BUSHING KBMM-40-DD-NR (R074224030) is a high-quality flange linear bushing designed for precision linear movement applications. This robust component features a central flanged design with two integrated wiper seals, ensuring protection against harsh environments and heavy contamination. The KBMM-40-DD-NR is crafted from rust-resistant standard metal, making it suitable for demanding conditions such as those found in woodworking, foundries, and cement plants. Its compatibility with stainless steel also allows for use in the medical, chemistry, and food industries. The bushing's construction includes a hardened and machined outer sleeve, ball retainer, balls, and flange all made of stainless steel to ensure durability and resistance to corrosion. The design incorporates many pockets acting as lubricant reservoirs which facilitate extended lubrication intervals or even lubrication for life under certain conditions. These pockets also serve to collect any dirt or debris that may enter the system to prevent jamming of the bushing. With a shaft diameter of 40 mm and an outer diameter sized appropriately for its series, this linear bushing ensures reliable operation within a permissible ambient temperature range of -30°C to +80°C. It boasts impressive load capacities: minimum dynamic load capacity Cmin and maximum dynamic load capacity Cmax based on total travel distance parameters. The product also offers maximum static load capacity Cmax and static longitudinal moment load capacity ML for different size L specifications. The KBMM-40-DD-NR is part of Bosch Rexroth's standard metal series of linear bushings and shafts, characterized by its central flanged format (M), providing a secure mounting solution. Weighing just 0.4 kg, this linear bushing delivers performance without adding significant weight to your assembly—ideal for various industrial motion systems where precision and reliability are paramount.
