What is an angular contact ball bearing?

There are different types of ball bearings available in the market. Although they may look quite similar, each has its own unique set of features that make it suitable for a range of different tasks. A company like Engineering Arrow will be able to help you make sure the ball bearing you choose is the best one for the project you have in mind if you’re not sure what you’re looking for. The angular contact ball bearing is just one of the different types of ball bearings you might consider. Here we will see what an angular ball bearing is and also some of the important features that you will find with this article.

Angular contact ball bearings

This type of ball bearing contains both an inner ring and an outer ring. These two rings move relative to each other in the direction of access to the bearing. Just like other types of ball bearings, the angular contact ball bearing is available in single and double row.

A single row angular contact ball bearing is the most commonly used item as part of a pair. It can be a back-to-back, tandem or face-to-face layout. They can also be used in a combination consisting of bearing sets.

The Double Row Angular Contact Bearing is a product that has been specifically designed to match two single row Angular Contact Ball Bearings that have been placed to run in a back-to-back arrangement. This type of ball bearing is ideally suited for use with combined axial loads in situations where axial space is somewhat limited.

Although not an angular contact ball bearing, the four point contact bearing is often useful in similar situations. It is a ball bearing specially designed to support the axial load that must be moved in both directions.

What are the characteristics of this type of ball bearing?

There are a number of very important characteristics of the angular contact ball bearing that make it a very important product to consider when finding the right ball bearing for your application.

  • They have a high axial load when supporting any form of capacity load in one direction only
  • They have one radial load carrying capacity
  • They offer high-speed capability
  • These are low maintenance ball bearings
  • They have low heat generation
  • They have a quiet operating volume

As for the actual appearance of the ball bearing, the angular contact ball bearing has only one high shoulder on its outer ring. This type of design ensures that the angular contact bearing is able to have high load carrying capacity. Additionally, the high shoulder also creates two intersecting lines and these lines form the contact angle on the bearing. Usually the standard contact angle will be between 15° and 25° (with a radial bearing it is 8°). It is this contact angle that allows the bearing to support not only a higher load but also a faster speed.

Applications of Angular Contact Ball Bearing

The increased axial load carrying capacity of this type of ball bearing, which results from the increased contact angle, makes it an ideal choice for use in a range of engineering, industrial and manufacturing applications. It is particularly useful when an original construction is required. These are just a few examples of applications where they could be used:

  • Industrial sectors
  • Fans
  • Pumps
  • Compressors
  • Gearboxes
  • Wind turbines
  • wind mill

I hope you now have more information on whether this would be the right bearing choice for your project. However, if you need further advice, why not contact a professional company to advise and support you in your choice?
