The Bosch Rexroth FLANGE LIN.BUSHING KBMM-16-DD-NR (R074221630) is designed with robustness and precision in mind, suitable for applications requiring high levels of durability and reliability. This central flanged linear bushing is constructed from standard metal with a rugged all-metal design, including a steel ball retainer that can withstand harsh environments and heavy contamination. The flange linear bushing is particularly tailored for use in demanding conditions such as woodworking, foundries, cement plants, and also finds application in stainless steel variants for the medical, chemistry, and food industries. The KBMM-16-DD-NR features an integrated wiper seal system that not only protects against contaminants but also serves to collect dirt to prevent jamming of the bushing. Its outer sleeve, ball retainer, balls, and flange are all made of hardened and machined stainless steel that ensures longevity and consistent performance. The product has multiple lubricant reservoirs which can lead to extended lubrication intervals or even lubrication for life under certain conditions. With a shaft diameter (d) size V and rows of balls designed for smooth linear motion, the bushing provides reliable operation with minimal friction force (FR) when not under radial load. It boasts a maximum dynamic load capacity (Cmax) that ensures it can handle significant loads during operation. The permissible ambient temperature range for this model spans from -20°C to 80°C when unsealed; however, it's important to note that higher temperatures may require unsealed variants without wiper seals. The FLANGE LIN.BUSHING KBMM-16-DD-NR has been engineered with attention to detail such as the minimum static load capacity (Cmin), maximum static load capacity (Cmax), dynamic load capacities based on total travel distance, as well as static longitudinal moment load capacity (ML). With a weight of 0.3 kg and dimensions tailored for its function, this linear bushing is an essential component for precise linear guidance systems where performance cannot be compromised by external conditions.
