The Bosch Rexroth SUPER LINEAR BUSH (R067221240) is a high-performance linear bushing designed for smooth and precise linear motion. This closed-type bushing, which lacks self-alignment features, is tailored for applications requiring the transfer of lower tipping forces along the axial direction. It is equipped with two seals to ensure low-maintenance operation and protection against contaminants. The SUPER LINEAR BUSH is constructed with steel bearing plates that have meticulously machined ball guide grooves and optimized ball lead-in chamfers, delivering exceptional travel smoothness and an extended service life. With a shaft diameter specification and a dynamic load capacity based on a total travel of 100,000 meters, this linear bushing can handle high travel speeds up to 5 meters per second. The integrated wiper seals contribute to minimized frictional drags when not under radial load, with the friction coefficient ranging between 0.01 to 0.25 depending on conditions such as speed and lubrication. The Bosch Rexroth SUPER LINEAR BUSH can operate within an ambient temperature range of -20°C to +80°C, making it versatile for various environmental conditions. Its outer diameter is precisely crafted for compatibility with corresponding components, while its breakaway force ensures reliable performance at startup. This model's balls are made from rolling bearing steel, offering durability and strength for repetitive use. The ball retainer and outer sleeve are made from either PA or POM materials, contributing to the bushing's robustness without requiring initial lubrication. With a weight of just 0.1 kilograms and minimal radial clearance between the shaft bore and the bushing, the SUPER LINEAR BUSH promises precision in its operation. It stands as an ideal solution for those seeking a low-cost yet high-quality linear motion component for their mechanical assemblies or automation systems.
