Product Description

Four-point Contact Ball Bearings china With Contact Angles35° or30° This type of bearing is separable formed bearings. The balls and rings have four contact points in order to bear radial load, axial load in any direction and radial-axial combined loads. The bearing can limit axial displacement in double directions of the axis or housing in the dimension of axial clearance. In comparison with deep groove ball bearings, the bearing has less axial clearance, heavier axial load capacity and higher limit rotational speeds. The bearing has lower axial load capacity than double row angular contact ball bearings with double outer (inner) rings. There can be two types: two half-outer-rings and two half-inner-rings according to the installation need of customers.
