The Bosch Rexroth SUPER LINEAR BUSH (R067211040) is a high-performance linear bushing designed for smooth motion and a long service life without the need for self-alignment features. This closed-type bushing is equipped with one seal, offering low-cost solutions for demanding applications. It is crafted with steel bearing plates that have precisely machined ball guide grooves and optimized ball lead-in chamfers, ensuring exceptionally smooth travel. The SUPER LINEAR BUSH operates efficiently with a shaft diameter of 'd' and supports high travel speeds up to 'vmax' meters per second, although the speed limit is advised to prevent excessive wear on plastic components. The design includes a ball retainer and an outer sleeve constructed from durable PA or POM materials, while the balls themselves are made from high-quality rolling bearing steel. This model does not come pre-lubricated, allowing users to apply their preferred lubrication based on operating conditions. It features integrated wiper seals which slightly increase friction force; however, this can be calculated by multiplying the base value by 1.25 as indicated in the footnote regarding friction force 'FR'. The dynamic load capacity of this bushing varies depending on the total travel distance, with specific multipliers provided for calculations based on 100,000 meters or 50,000 meters of travel. With its robust construction and meticulous design to reduce frictional drag under various conditions of speed and lubrication, the Bosch Rexroth SUPER LINEAR BUSH maintains a low friction coefficient ranging from 0.01 to 0.05 under normal operating circumstances. It has been tested for total travels ranging from 10^8 m to 10^10 m without failure. The product operates effectively within an ambient temperature range of -20°C to +80°C. Weighing in at just 0.5kg and offering precision in radial clearance on shaft bores (K, H, M), this linear bushing is an ideal component for precise linear movement in various applications.
