The Bosch Rexroth STD.LINEAR BUSHING KBM-O-25-D (R063102500) is a high-quality linear bearing designed for smooth and precise linear motion. This standard metal open linear bushing is equipped with a single seal and has been engineered to operate effectively in harsh environments and under heavy contamination, thanks to its rugged all-metal design with a steel ball retainer. The bushing's many pockets act as lubricant reservoirs, which can extend lubrication intervals or even allow for lubrication for life. Featuring a hardened and ground outer sleeve, this linear bushing ensures durability and reliable performance. Its balls are made of rolling bearing steel, arranged in multiple rows within the steel ball retainer. This design facilitates the collection of dirt and debris into the pockets to prevent jamming of the linear bushing mechanism. The KBM-O-25-D is particularly suitable for applications such as woodworking, foundries, and cement plants where environmental conditions are challenging. The absence of wiper seals combined with integrated steel retaining rings allows it to withstand higher temperatures, especially with shaft diameters 25 mm and above. With its dynamic load capacity C and static load rating C0 tailored for the main direction of loading, this linear bushing exhibits excellent load-handling capabilities. It has been designed to accommodate maximum accelerations while maintaining low friction coefficients under various load conditions. The permissible ambient temperature range for operation extends from -30°C up to 80°C without compromising functionality or performance. This product has an outer diameter (D) size E of 40 mm, a breakaway force requirement, and supports maximum permissible linear speeds. Weighing approximately 0.18 kg, it provides optimal radial clearance between the shaft and bore for precise operations. The Bosch Rexroth STD.LINEAR BUSHING KBM-O-25-D is a robust component suitable for demanding applications requiring high reliability in linear motion systems.
