ANGULAR CONTACT BALL BEARING

An angular contact ball bearing is a type of rolling-element bearing designed to support combined radial and axial loads, as well as pure axial loads, in a specific direction. It achieves this by using races inclined at an angle to the bearing axis, which enables it to withstand both radial and axial forces simultaneously.

Key features of angular contact ball bearings include:

Raceway Design

The inner and outer races of an angular contact ball bearing are typically designed with a groove at an angle to the bearing axis. This angle is known as the contact angle and is usually between 15 and 40 degrees. The contact angle determines the bearing's ability to handle axial and radial loads.

Ball Bearings

Angular contact ball bearings typically have steel balls positioned between the inner and outer races. These balls are usually arranged in a single row, but double-row configurations are also available for higher load capacities.

Cage or Retainer

A cage or retainer holds the balls in place within the bearing, maintaining their spacing and alignment. This ensures smooth operation and prevents contact between the balls, which could lead to friction and premature wear.
