The Bosch Rexroth SUPER LINEAR BUSH (R067122040) is a high-performance linear motion bearing designed for precision applications that require smooth and accurate movement along a linear path. This model boasts an open design with self-alignment features, ensuring it can compensate for shaft deflection and misalignment up to specified limits. The SUPER LINEAR BUSH is equipped with two seals to protect against contaminants while providing low friction travel. Constructed with steel bearing plates that have machined ball guide grooves and optimized ball lead-in chamfers, this linear bushing promises a long service life and exceptionally smooth travel. It is particularly suitable for use on fully supported shafts where precise substructures are critical, as it prevents warping that can occur with other types of linear guides. The bushing's dynamic load capacity is optimized for the main direction of loading, allowing for high travel speeds of up to 5 meters per second, although these speeds may limit the service life due to increased wear on plastic parts. Despite this, tests have indicated a robust performance range without failure from 100 km to 10,000 km. The product also features a ball retainer and outer sleeve made from either PA or POM materials, while the balls themselves are crafted from rolling bearing steel. The SUPER LINEAR BUSH operates efficiently within a permissible ambient temperature range of -30°C to +80°C. Its design includes integrated wiper seals to prevent the need for initial lubrication and minimize maintenance requirements. With its low breakaway force and minimal friction coefficient under varying loads, this Bosch Rexroth linear bushing ensures reliable operation in diverse conditions. This model has a size E designation with an outer diameter (D) specification provided in its technical details. The radial clearance between shaft and bore comes in different classifications (K, H, M), offering flexibility according to application needs. Weighing just 0.2 kg, it provides a balance between robust construction and ease of handling during installation or replacement procedures.
