Deep Groove Ball Bearings Versus Angular Contact Ball Bearings

Ball Bearings

Ball bearings are frequently used in machinery and instrumentation to minimize rotational friction and reduce stress. Ball bearings are designed to support radial or axial (thrust) loads or a combination of the two.

There are several types of commercially available ball bearings that are intended to fit specific needs. However, this page will focus specifically on the difference between radial deep groove ball bearings and angular contact ball bearings. Although deep groove ball bearings and angular contact ball bearings are both types of ball bearings, these two bearing types have very distinct characteristics and are designed to be used in different applications.

Deep Groove Ball Bearings

Deep groove ball bearings are a type of radial ball bearing, which is the most widely used bearing due to its versatility. Deep groove ball bearings are used to transmit loads from rotating parts to housings with minimal friction losses. Deep groove ball bearings support axial and radial loads in both directions and are suitable for high speeds. A distinct advantage over angular contact ball bearings is that they can accept axial load in both directions.

Angular Contact Ball Bearings

Angular contact ball bearings, sometimes referred to as spindle bearings, are typically used in machinery that requires high performance and high accuracy. They can carry both radial and axial loads. The loads are transferred from one raceway to the other through the bearing balls along a specifically designed contact angle; GMN carries 15°(C), 25°(E), and other custom contact angles. Angular contact bearings have a much higher speed rating than radial ball bearings because of the constant contact of the balls to both raceways.

Ball Bearing Comparison Chart

The chart below shows the advantages, usages, and applications for deep groove and angular contact ball bearings.

Ball Bearing Deep Groove Angular Contact
  • Can accept axial load in both directions
  • Lower contact angle (~8°)
  • Outstanding dynamic parameters
  • Highest processing speed
  • Low production & maintenance costs
Use When
  • Axial loads from both directions need to
    be transmitted
  • Existing space does not allow installation of
    matched spindle bearings
  • Speed is less important
  • High speed is required
  • Best possible guidance of rotating parts is required
  • High Rigidity and Precision is required
  • Medical industry
  • Vacuum technology
  • Dry lubrication low out gassing
