Deep Groove Ball Bearings Versus Angular Contact Ball Bearings

High precision bearings are important in machinery that requires reliability, fast rotational speed and heavy use. These types of bearings are designed to support loads (weight) applied radially and/or axially to the bearing.

This article is intended to focus specifically on the difference between radial deep groove ball bearings and angular contact ball bearings which have very distinct characteristics and are used in different applications and industry’s.

Deep Groove Ball Bearings

Also referred to as radial ball bearings, these bearings are the most popular and widely used in industrial machinery applications because of their versatility.

Deep groove ball bearings carry loads from rotating parts to the shaft and/or housing with minimal friction. A distinct advantage that radial, deep groove, ball bearings have over angular contact ball bearings is that they can accept axial loads in both directions.

Deep groove ball bearings have a small contact angle of around ~8° to help reduce stress on the bearing that is caused by moderate weight of the load they are supporting.

Angular Contact Ball Bearings

Sometimes referred to as spindle bearings, these bearings are used in machinery that requires high accuracy and reliability.

Angular contact bearings have a much higher speed rating than radial ball bearings because of the nonstop contact of the balls to both raceways.

Angular contact bearings can carry both radial and axial loads that are transferred from one ring to the other, through the balls, along a specific contact angle. The contact angle is measured by two intersecting lines, one that’s formed at the point of contact between the ball and the raceway(s) and the other that’s formed from the perpendicular axis of rotation to the bearing.

We stock 15°(C) and 25°(E) angular contact bearings but can customize other contact angles as needed.
