High Precision Large Size Bearing,Crossed Roller Bearings are thin-wall bearings consisting of an inner ring, a two-part outer ring, cylindrical rollers, and separators. The rollers are oriented at right angles to each other and kept apart by separators. Crossed Roller Bearings can sustain axial loads in both directions as well as radial loads and strong moment loads. Offering high load capacity within a light and compact envelope, they are widely used in the rotating joints of robots
