The Bosch Rexroth STD.LINEAR BUSHING KBM-E-8 (R061030800) is a high-quality linear motion component designed for a range of industrial applications. This standard metal linear bushing is characterized by its adjustable radial clearance and rugged all-metal design, which includes a steel ball retainer suitable for harsh environments and heavy contamination. The KBM-E-8 is engineered to operate without seals, enabling it to withstand extreme temperatures well above 100°C or under vacuum conditions. This linear bushing's design incorporates many pockets that act as lubricant reservoirs, allowing for extended lubrication intervals or even lubrication for life. The absence of wiper seals and the inclusion of integrated steel retaining rings permit the bushing to accommodate higher operating temperatures when used with shaft diameters of 12mm and above. The hardened and ground outer sleeve enhances durability while the steel ball retainer ensures smooth motion; for shaft diameters of 12mm and 16mm, a plastic retainer made of PA is used. With four rows of balls made from rolling bearing steel, the KBM-E-8 provides reliable load-bearing capacity. It has a maximum dynamic load capacity (Cmax) that varies based on travel distance, with adjustments necessary if based on travel distances other than the standard 100,000m. The friction coefficient ranges from 0.01 to 0.02 under lubrication with oil, though this can vary depending on load conditions. The Bosch Rexroth STD.LINEAR BUSHING KBM-E-8 is particularly suitable for applications in woodworking, foundries, and cement plants where it can prevent jamming by collecting dirt within its pockets. It offers an outer diameter (D) size E (14mm), breakaway force specifications, maximum permissible linear speed (vmax), along with minimum static and dynamic load capacities that ensure robust performance in demanding situations. With a weight of 0.04kg and specific radial clearance specifications, this linear bushing stands as an adaptable solution in precision linear motion tasks.
