The Bosch Rexroth STD.LINEAR BUSHING KBM-O-40-DD (R063204000) is a robust linear motion component designed for high-load and high-wear applications. This open standard linear bushing features a hardened and ground outer sleeve, providing exceptional durability and precision. The steel ball retainer ensures smooth motion and accommodates heavy contamination common in harsh environments such as woodworking, foundries, and cement plants. With a shaft diameter of 40 mm, the KBM-O-40-DD is equipped with two seals to protect against contaminants while retaining lubrication. The design includes many pockets that act as lubricant reservoirs, potentially extending lubrication intervals or even allowing for lubrication for life. The bushing is seal-free with steel ball retainers that are capable of operating at temperatures well above 100°C or under vacuum conditions. The dynamic load capacity of this linear bushing is substantial, ensuring it can handle the demands of heavy-duty industrial applications. It also features an integrated wiper seal option to prevent dirt ingress and jamming without compromising its ability to withstand higher temperatures for shaft diameters of 40 mm and above. This product has been engineered to provide low friction movement with a coefficient ranging from 0.01 to 0.02 under oil lubrication, which may vary depending on load conditions. Its design allows for both axial and radial securing without the need for a locating hole for certain shaft diameters. In summary, the Bosch Rexroth STD.LINEAR BUSHING KBM-O-40-DD offers reliable performance in extreme conditions with minimal maintenance requirements, making it an ideal choice for applications requiring robust linear guidance systems.
