Crossed roller bearing CPM 2845

radialaxialsteel

Crossed roller bearings. The main feature of this bearing is that the cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, in a 90° V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including radial, axial and moment loads. Since the Cross-Roller bearing achieves high rigidity despite the minimum possible dimensions of the inner and outer rings, it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers and medical equipment. The spacer retainer fitting among cross-arrayed rollers prevents rollers from skewing and the rotational torque from increasing due to friction between rollers. Thus, even under a preload, the Cross-Roller Bearing provides stable rotation. Since the inner and outer rings are designed to be separable, the preload can be adjusted, and this feature enables accurate rotation. The crossed roller bearings that CPM designs and manufactures, go from 10 mm bore up to 800 mm external diameter. Like for the slewing rings, these bearings may be supplied with internal or external gear, they can be sealed or have any other required characteristic.
