The Bosch Rexroth STD.LINEAR BUSHING KBM-50 (R060005000) is a high-quality, standard linear bushing designed for self-supporting shafts and is characterized by its rugged all-metal construction with a steel ball retainer. This makes it suitable for harsh environments and heavy contamination, such as those found in woodworking, foundries, and cement plants. The KBM-50 is engineered without seal to allow for higher permissible ambient temperatures, especially with shaft diameters of 50 mm and above. This linear bushing features many pockets that act as lubricant reservoirs which contribute to extended lubrication intervals or potentially lubrication for life. The steel ball retainer not only ensures durability but also facilitates smooth movement. The balls are made from rolling bearing steel which enhances the bushing's performance under load. The KBM-50's hardened and ground outer sleeve provides additional robustness. It has been designed to prevent jamming by collecting any dirt that may infiltrate the bushing through its multiple lubricant pockets. The product comes equipped with integrated steel retaining rings instead of wiper seals, allowing it to withstand higher temperatures. With a weight of 0.7 kg, the KBM-50 offers a maximum dynamic load capacity (Cmax) and minimum dynamic load capacity (Cmin), ensuring reliable operation over its lifespan based on total travel distance considerations. It can handle a maximum acceleration (amax) and operates efficiently within a permissible ambient temperature range of -30°C to +80°C without seals. The closed format of the linear bushing allows for use with supported shafts while maintaining a compact form factor. Its friction coefficient ranges from 0.01 to 0.02 under oil lubrication conditions, providing low resistance during motion even under heavy loads—though it should be noted that this can vary depending on various factors including speed and radial load. Overall, the Bosch Rexroth STD.LINEAR BUSHING KBM-50 offers robust performance for demanding industrial applications where reliability and durability are critical considerations.
