The Bosch Rexroth STD.LINEAR BUSHING KBM-20-DD (R060202010) is a high-quality standard linear bushing designed for robust applications. This closed-type bushing is equipped with two seals to ensure protection against contaminants, making it suitable for use in harsh environments such as woodworking, foundries, and cement plants. The KBM-20-DD features a rugged all-metal design with a steel ball retainer that can withstand heavy contamination and demanding operational conditions. With its many pockets acting as lubricant reservoirs, this linear bushing is capable of extended lubrication intervals or even lubrication for life, minimizing maintenance needs. The steel ball retainer is complemented by a hardened and ground outer sleeve that accommodates shaft diameters d, ensuring stable and precise linear motion. For shaft diameters d and higher, the bushing allows for higher operating temperatures due to integrated steel retaining rings instead of wiper seals. This product's design includes balls made of rolling bearing steel and multiple rows of balls within the assembly which contribute to its high load capacity. The KBM-20-DD has been engineered with attention to preventing jamming; pockets within the bushing collect dirt and debris that may infiltrate the system. The dynamic load capacities of the Bosch Rexroth STD.LINEAR BUSHING are based on a total travel distance of 100 km but can be adjusted for longer distances. It operates efficiently within an ambient temperature range from -30°C to +80°C without wiper seals, while maintaining low friction coefficients under various load conditions. Its breakaway force ensures reliable starting movement under static conditions. Weighing in at 0.2 kg, this linear bushing is an essential component for linear motion systems requiring durability and reliability in extreme conditions. Its design reflects Bosch Rexroth's commitment to producing components that meet stringent performance standards while addressing practical industrial needs.
