What is a tapered roller bearing?

A tapered roller bearing is a bearing that consists of two parts:

  • The cone, which is the inner cage with the rollers
  • The cup, which is the outer cage

This type of bearing is generally offered in a standard version, without sealing. However, you can also find some with a seal to prevent contaminants from infiltrating. Taper roller bearings, which consist of the cone and cup, are usually removable. That is, the inner ring, together with the cage-roller assembly, forms a unit that can be mounted independently of the outer ring. This facilitates mounting, dismounting and routine maintenance inspections.

What are tapered roller bearings used for?

Tapered roller bearings are designed to support both radial and axial loads. The contact angle largely determines the axial load carrying capacity of bearings. The larger the contact angle, the greater the axial load-carrying capacity. It is important to remember that this type of bearing can only support axial loads in one direction.

When are tapered roller bearings used?

For all these reasons, tapered roller bearings are used in many fields such as agriculture, railway, industry, etc. In addition, the friction and noise level are considerably reduced due to the lubricating film. It is the most widely used type of bearing after the ball bearing.

The main application areas of tapered roller bearings are as follows

  • Gearboxes
  • Differentials
  • Transmissions
