Angular contact ball bearings

详情

The contact angle  is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane along which the load is transmitted from one raceway to another and a line perpendicular to the bearing axis.

The allowable angle error of a single row contact ball bearing is limited. The angle errors of inner ring and outer ring are depended on radial clearance bearing dimension internal structure and the force or force moment acting on bearings. The relationship of those factors is so complicated that an accurate number cant be given at present.

If the clearance of paired angular contact ball bearings(or double-row angular contact ball bearing) especially of those arranged back to back is respectively small balls and cages would accommodate more extra load. Once angular errors were made between inner ring and outer ring the bearing life would be shortened. Any angular error would cause noise.
