Provide high-quality bearing products to customers around the world.

Four-point contact ball bearings can accommodate high axial loads in both directions and small radial loads.They can operate at very high speeds and are more suitable than deep groove ball bearings for supporting large axial forces. The outer ring, with ball and cage assembly, can be mounted separately from the two inner ring halves.
