High precision bearings are important in machinery that requires reliability, fast rotational speed and precision.
But precision radial ‘deep-groove’ ball bearings & angular contact bearings are not interchangeable.
Let’s dive in and start to demystify these two different types of precision bearings. By the end of this article, you will know:
A radial ball bearing is a type of precision bearing where the action of the load transmitted is radial to the axis of the shaft. They are the most popular and widely used in industrial machinery applications because of their versatility.
Radial ball bearings produce very little friction as they carry loads from
rotating parts to the shaft and/or housing. They also have a small contact angle of ~ 8° that helps reduce the stress caused by the weight of
the load they are supporting.
A distinct advantage of radial bearings is they can accept axial loads in both directions and don’t need to be purchased in sets, unlike angular contact bearings.
Sometimes referred to as “spindle bearings,” angular contact bearings are used in machinery that requires high accuracy and durability.
Angular contact bearings have a much higher speed rating than radial bearings because of the nonstop contact of the balls to both rings.
Angular contact bearings can carry both radial and axial loads. The weight of the load is 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 ring and the other that’s formed from the axis of rotation to the bearing
15° and 25° contact angles are the most common but other angles can be customizes as needed.
