Product analysis
Angular contact bearing
Angular contact ball bearings are especially suitable for bearing composite loads, i.e. both
radial and axial loads. The bearing capacity of axial loads increases with the increase of
contact angle A. The contact angle is defined as the angle between the common normal of
the contact point between the rolling body and the raceway or the contact center line and
the radial plane of the bearing. The load is transferred from one raceway to another raceway
along the connection line. For single row bearings, the contact angle can be identified by
suffixes of different codes.
Single row angular contact ball bearing
1.structure characteristics
Single row angular contact ball bearings can only bear unidirectional axial loads. Under the action of
radial load, there will be an axial force in the bearing, which needs to be adjusted by a reaction force.
Therefore, this kind of bearing generally needs to rely on the second bearing to balance.
Single row angular contact ball bearings can be loaded with more steel balls, so that the bearing has
a higher load-carrying capacity. The contact angles are 15 degrees, 25 degrees, 40 degrees, and
the suffixes are C, AC, B, respectively.
2.Composition and preload
According to the structural characteristics of single row angular contact ball bearings, these bearings
are usually used together by two or more bearings of the same type.
