The Bosch Rexroth STD.LINEAR BUSHING KBM-3-NR (R060000330) is a robust, corrosion-resistant linear bushing designed for harsh environments and heavy contamination. This standard metal, closed linear bushing is engineered without seals and features a steel ball retainer, making it ideal for applications requiring high durability and resistance to wear. It boasts many pockets that act as lubricant reservoirs, contributing to extended lubrication intervals or even allowing for lubrication-free operation. The KBM-3-NR's construction includes a hardened and machined outer sleeve, ball retainer, integrated retaining rings, and balls all made from stainless steel of a grade comparable to industry standards. This choice of materials ensures its suitability for sectors such as the medical, chemistry, and food industries due to its stainless steel composition. Additionally, it is well-suited for use in demanding conditions like woodworking shops, foundries, and cement plants where dirt and debris are prevalent; the design of the bushing's pockets helps collect any dirt that may enter to prevent jamming. This linear bushing is designed for self-supporting shafts with a shaft diameter 'd' specification. The product also features an outer diameter 'D' and operates efficiently within a permissible ambient temperature range of -30°C to +80°C. For applications involving higher temperatures, only unsealed linear bushings with steel ball retainers like this model should be considered while accounting for reductions in load capacity. With dynamic load capacity specifications based on total travel distance (with factors provided for different travel lengths), the KBM-3-NR offers reliable performance under varying operational loads. It also has specified minimum and maximum static load capacities. The friction coefficient remains low under heavy loads but can vary depending on conditions such as speed and lubrication status. In summary, the Bosch Rexroth STD.LINEAR BUSHING KBM-3-NR (R060000330) provides a rugged solution for linear motion requirements in environments where durability and reliability are paramount. Its design facilitates maintenance-free operation while ensuring longevity even in the presence of contaminants.
