NOTE:

1. Models in this brochure are standard,inner and outer diameter are free tolerance. If there are matching requirements of host-machine,please mark the size and precision on the contract or attached drawing.

2. Provides design & solutions for OEM, each special, individual need.

XI120288 Bearing is composed of 2 seat-rings, and with the features of compact structure, light weight. The balls contact with the circular raceway at four points, via which the axial force, radial force and tilting moment can be born simultaneously.Mainly be used in slewing conveyors, welding arms and manipulators, small and medium cranes, excavators, and other engineering machines.
