Cross roller bearings consist of inner rings, outer rings, spacer retainers and cylindrical
rollers cross arranged on the V-shaped *0° groove between the inner and outer rings. This
structure can withstand radial, axial and moment loads in all directions because the rollers
line contact with raceway surfaces achieve a large load-bearing area despite the minimum
dimensions. Therefore these bearings are widely used on the rotating parts of industrial
robots, machine tools, precision rotary tables, measuring instruments and IC
manufacturing machines.
