Bosch Rexroth 67121240, Bearing with 22mm Outside Diameter / 4894045

Super Ball Bushings with Seals - Series R0670 ; R0671. The Super-Linear Bushing has a built-in inertial error compensator, that compensates for the angle between the housing and shaft up to 0.5 degrees tilt without reducing the capacity due to angular pressure. Possible causes for internal errors include shaft flex due to heavy loads or inaccuracies in the connecting construction. The self-adjustment ensures effortless lead-in of the bearings into the loaded zone and even load distribution over the entire bearing row. The result is unparalleled smooth motion and a very high load capacity for the Linear Bushing. High travel speeds 5 m/s Offers shaft deflection and self-alignment up to 0.5 degrees Ball retainer with outer sleeve made of polyamide Hardened steel segmental load bearing plates with ground ball tracks Balls made from anti-friction bearing steel
