Tapered roller bearings comprise solid inner and outer rings with tapered raceways and tapered rollers in a window cage.
The bearings are in the form of:
standard designs
open variants matched in pairs
integral designs sealed on one side, JK0S.

Open bearings are not self-retaining. As a result, the inner ring with the rollers and the cage can be fitted separately from the outer ring. Metric and inch size bearings are available. Designs with a K in the designation have inch dimensions. For new designs, however, bearings in metric sizes should always be used in preference.

Radial and axial load capacity:
Tapered roller bearings can support axial loads in one direction and high radial loads. They must normally be axially adjusted against a second bearing fitted in a mirror image arrangement. This bearing combination is fitted in an O or X arrangement.

Contact angle:
The axial load carrying capacity is dependent on the contact angle; i.e. the larger the angle, the higher the load to which the bearing can be subjected.
The size of the contact angle and thus the load carrying capacity is indicated by the bearing-specific value. Bearings of series 313, 323..-B, T5ED and T7FC have a very high axial load carrying capacity due to their particularly large contact angle.

Matched bearings:
Tapered roller bearings could be matched in pairs in an X arrangement and can therefore support high axial forces in both directions and moment loads. The axial internal clearance of the bearing pair is defined by a ring between the two outer rings and is indicated in the suffix.
We can also supply tapered roller bearings by agreement as matched pairs in an O arrangement

Sealing:
Tapered roller bearings of standard design and matched in pairs are not sealed.
Integral tapered roller bearings JK0S have a lip seal on one side.

Lubrication:
Tapered roller bearings of standard design and matched in pairs can be lubricated with oil or grease.
Integral tapered roller bearings JK0S are filled with a high quality grease.

Operating temperature:
Open tapered roller bearings can be used at operating temperatures from –30 °C to +120 °C. For continuous operating temperatures above+120 °C, please contact us.
Bearings with a lip seal can be used at operating temperatures from–30 °C to +110 °C, restricted by the grease and sealing ring material.
