Bearings 33120

Tapered roller bearings use tapered rollers that roll around the tapered guide faces on the inner and outer rings. These bearings are difficult to handle very high radial and axial (in one direction) loads. Bearings of this type are usually mounted in pairs similar to thrust ball bearings. In this case, adequate internal clearance can be achieved by adjusting the axial distance between the inner or outer rings of two opposing bearings. Due to the construction of these bearings, the inner and outer rings can be mounted separately.
Depending on the contact angle, tapered roller bearings are divided into 3 types: normal angle, medium angle and deep angle. In addition, there are 4-row and 2-row tapered roller bearings.
Cage made of stamped steel is commonly used.
The international designation for metric tapered roller bearings usually has 5 digits starting with 3.

Tapered roller bearings are commonly used to support combined loads mainly consisting of radial loads. Their cups are separable for easy assembly During mounting and use, the radial clearance and axial clearance can be adjusted and preload installation can be performed.
