Angular Contact Ball Bearing- Single Row / Double Row Ball Bearing

Image of Angular Contact Ball Bearing

Angular Contact Ball Bearing is ideal for applications that require high accuracy and good high-speed performance. These kinds of bearings are required to carry a combined load. Angular contact bearings come in different types and angles. The standard angles are 15 degrees, 30 degrees, 40 degrees. 

Angular Contact Ball Bearings also come in matched pairs as back-to-back (DB), face-to-face (DF), and Tandem arrangements. Angular Contact Bearing is also available in Double Row consisting of two single-row angular contact ball bearings matched back to back with integrated inner and outer rings. 

Specialized Angular Contact Ball Bearing comes in a four-point contact angle of 35 degrees consisting of an inner ring divided into two pieces.

Features And Benefits Of Angular Contact Ball Bearing

  • Bearing rings and balls possess their own contact angle that is normally 15°, 30° or 40°.
  • Bearings with a smaller contact angle are more suitable for applications involving high-speed rotation.
  • Those with a larger contact angle feature superior axial load resistance.
  • Single-row angular contact ball bearings can accommodate radial load and axial load in one direction.
  • DB and DF matched pair bearings and double-row angular contact ball bearings can accommodate radial load and axial load in both directions.
  • DT matched pair bearings are used for applications where axial load in one direction is too large for one bearing to accept.
  • Angular contact ball bearings are used for high accuracy and high-speed operation.

Application And Uses Of Angular Contact Ball Bearing

  • Angular contact ball bearings are often preloaded to enhance their rigidity and rotating performance.
  • For high-precision matched pair angular contact ball bearings of class 5 or higher, which are used in machine tools and other precision equipment, the standard preload is specified in three levels: light(L), medium(M), and heavy(H).
