Excavator bearing

Excavator specialized angular ball bearing are used for the appliion of excavator machinery. This kind of angular contact ball bearing has big contact angle (40 degree), so can under take big axial load, and aslo axial radial allied load. Moreover it can carry heavier load capacity than the same size bearings because it has more balls inside.
