The Bosch Rexroth STD.LINEAR BUSHING KBM-O-20-D (R063102000) is a high-quality, open linear bushing designed for a variety of applications requiring precise linear motion. This standard metal linear bushing features a rugged all-metal design with a steel ball retainer, making it suitable for harsh environments and heavy contamination. Its construction includes many pockets that act as lubricant reservoirs to extend lubrication intervals or even allow for lubrication for life, ensuring reliable performance over time. The KBM-O-20-D model has been engineered with a hardened and ground outer sleeve and balls made of rolling bearing steel to provide smooth movement and high durability. The steel ball retainer is designed to handle temperatures well above 100°C or under vacuum conditions without the need for seals. For shaft diameters of 12mm and higher, the bushing can operate at even higher temperatures due to the absence of wiper seals and the inclusion of integrated steel retaining rings. This linear bushing comes equipped with one seal and features a locating hole for axial and radial securing, though no locating hole is provided for shaft diameters below 12mm. The standard version is optimized for use in demanding environments such as woodworking shops, foundries, and cement plants where dirt ingress is common; its design allows any dirt that may enter to be collected in pockets to prevent jamming. With its dynamic load capacity C noted at 830 N, static load rating C0 at 1,250 N, breakaway force starting from 5 N, and maximum permissible linear speed vmax at 5 m/s, this Bosch Rexroth linear bushing ensures robust performance across various applications. It also has a friction coefficient ranging from 0.01 to 0.02 under oil lubrication conditions. The permissible ambient temperature range extends from -30°C up to +80°C without seals. Overall, the STD.LINEAR BUSHING KBM-O-20-D offers an efficient solution for linear motion requirements in settings where durability and reliability are paramount. With its comprehensive design features focused on longevity and performance under challenging conditions, it stands as an exemplary choice within its product group ID R063102000.
