The Bosch Rexroth SUPER LINEAR BUSH (R073222040) is a high-precision linear bushing designed to facilitate the movement of heavy loads with utmost accuracy. This closed-type linear bushing features a shaft diameter 'd' and is equipped with two seals for enhanced protection and longevity. The SUPER H series bushing incorporates hardened steel load-bearing plates with meticulously machined ball guide grooves, as well as a steel load-bearing plate back, ensuring maximum precision. With more tracks than the SUPER A series, this linear bushing is capable of compensating for shaft deflection and misalignment up to specified limits while maintaining a high travel speed. It can withstand a maximum acceleration 'amax' and operates within a permissible ambient temperature range of -30°C to +80°C. The outer diameter 'D' is designed to fit seamlessly into corresponding assemblies, while the dynamic load capacity 'C' and static load rating 'C0' indicate its ability to handle various loading conditions in the main direction of loading. The friction coefficient ranges from 0.01 to 0.02 under different loads, ensuring smooth operation. The product also features an optional integrated double-lipped wiper seal that minimizes contamination ingress. In terms of construction, the SUPER LINEAR BUSH boasts a POM ball retainer and balls crafted from rolling bearing steel, ensuring durability and consistent performance. Two metal holding rings secure the assembly, while multiple rows of balls ensure reliable guidance and support for the moving elements. The overall weight of this linear bushing is 0.3 kg, signifying its robust yet manageable design suitable for various applications. Its radial clearance options cater to different fit requirements, ensuring compatibility with diverse operational needs. The Bosch Rexroth SUPER LINEAR BUSH stands out as an essential component for linear motion systems requiring high precision and reliability in heavy load applications.
