Angular contact ball bearing types

381 Published by admin Mar 27,2023

Angular contact ball bearings can bear both radial and axial loads due to their contact angle a. The contact angle is defined as the angle between the common normal of the contact point of the ball and the raceway and the radial plane. According to different structures, angular contact ball bearing types are divided into single row and double row.

ball bearing types

Single Row Angular Contact Ball Bearings

Single row angular contact ball bearings can accommodate radial and axial loads. Although this kind of bearing can only bear axial load in one direction, it can be used in combination with another bearing that bears reverse load. Angular contact ball bearings cannot be disassembled. Angular contact ball bearings are suitable for high speeds and have very limited self-aligning capabilities.

Single row angular contact ball bearing types:

Bearings with contact angles A (30°) and B (40°). Bearings with a contact angle of C (15 degrees) are generally used for high-precision bearings. Single row angular contact ball bearings are hardly used alone. Usually they are used in two or more configurations and there are three different pairing types: DB: Back-to-back configuration. DF: face-to-face configuration. DT: Tandem configuration.BALL BEARING

Double Row Angular Contact Ball Bearings

The structure of the double row angular contact ball bearing is similar to a pair of single row angular contact ball bearings arranged in an O shape. This kind of bearing can withstand large radial load and bidirectional axial load, so it is especially suitable for occasions that require rigidity and axial fixation. It has very limited self-alignment capabilities.

Double row angular contact ball bearing types:

The contact angle of this type of bearing is 20 degrees and 30 degrees, and the bearing type is selected according to the size of the axial load and moment.
