Tapered roller bearings, also known as taper bearings, are a type of rolling element bearing that are designed to support both radial and axial loads. They have a conical shape and are made up of tapered rollers, which are arranged in a way that allows for the bearing to handle both radial and axial loads.

Tapered roller bearings work by having the inner raceway cone and the outer raceway cup come together at a common point on the bearing’s axis. The tapered rollers are positioned in between the cone and cup, and they roll along the raceway surfaces as the bearing rotates. This rolling action distributes the load evenly across the rollers, allowing the bearing to handle both radial and axial loads.

One advantage of tapered roller bearings is that they are able to handle both radial and axial loads, which makes them suitable for applications that require high radial and axial rigidity. They are also able to handle high speeds and can operate at higher temperatures than other types of bearings.

Overall, tapered roller bearings are a reliable and efficient type of bearing that are widely used in a variety of applications, including automotive, aerospace, and industrial equipment.
