Ball transfer units
Bosch Rexroth linear motion
This category lists Bosch Rexroth ball transfer units and tolerance rings. The tolerance rings come in the AN, ANS and BN series, with the type designation giving nominal diameter and width (for example AN125X22, AN60X15, ANS130X20, BN20X16, BN40X40). Tolerance rings are corrugated spring-steel elements for force-fit, backlash-free shaft-hub and bearing-seat connections; ball transfer units support and guide workpieces in multiple directions.
Typical applications: Tolerance rings secure bearing seats and shaft-hub connections in machine building, gearboxes and drive technology, where production tolerances have to be compensated and vibration damped. Ball transfer units are found at conveyor, handling and assembly stations for the free movement of loads. Selection follows series (AN, ANS, BN), nominal diameter and width according to seat diameter and required transmission force.
