The Bosch Rexroth SUPER LINEAR BUSH (R067115040) is a high-performance linear motion bearing designed for precision and durability. This open-type linear bushing, part of the Super LB A series, features a self-alignment capability that compensates for shaft deflection and misalignment up to certain limits, ensuring smooth operation even on imprecise substructures. It is equipped with one longitudinal seal and does not require initial lubrication, simplifying maintenance and setup. Constructed with steel bearing plates that have meticulously machined ball guide grooves and optimized ball lead-in chamfers, the SUPER LINEAR BUSH ensures exceptionally smooth travel and an extended service life. The product can handle high travel speeds of up to 5 meters per second (ms) and is capable of absorbing maximum accelerations, making it suitable for dynamic applications. The bushing's ball retainer and outer sleeve are made from durable PA or POM materials, while the balls themselves are crafted from rolling bearing steel. This combination provides a robust construction that can withstand substantial static and dynamic loads in the main direction of loading. The SUPER LINEAR BUSH operates effectively within a temperature range of -30°C to +80°C. It has a size E designation with an outer diameter D of 50 mm. The dynamic load capacity C is specified by the manufacturer, as well as the breakaway force required to initiate motion. The friction coefficient varies depending on load conditions but remains within an optimal range for efficient operation. Weighing approximately 0.2 kg, this linear bushing offers low radial clearance on the shaft bore, ensuring precision in mounting and alignment. Its design includes integrated wiper seals which protect against contaminants while minimizing frictional drags when not under radial load. Overall, the Bosch Rexroth SUPER LINEAR BUSH (R067115040) is engineered for applications requiring precise linear movement with high reliability and ease of use, making it an excellent choice for various industrial motion systems.
