Tapered Roller Bearings

Tapered roller bearings with a single row of rollers are always mounted opposing another bearing of the same type to provide a rigid assemblies, particularly when preloaded.

Tapered roller bearings are usually equipped with a pressed steel cage. In some cases with a synthetic material cage.

The rings of this bearing are detachable: the outer ring (Cup) is not joined to the rest of the bearing which is made up of the inner ring (Cone) and rollers held on the cone by the cage. A tapered roller bearing can accept axial loads in one direction only. It must be mounted in opposition with a bearing of the same type.

ISO 355 Standard defines the different series of tapered roller bearings with contact angles of 10 to 30 degrees. For a given radial load, the greater the angle of the cup, the greater the axial load that the bearing can withstand.

The tapered roller bearing is an angular contact bearing that can withstand high radial and axial load.

the shape of the contacting profiles allows misalignment in the range of 0.06 degrees.
