Product Detail

Tapered roller bearings are mainly used to bear radial and axial combined loads, mainly radial load; while tapered roller thrust bearings with large taper angle can be used to bear radial and axial combined loads, mainly axial loads. Tapered roller bearing is is of separate type, and its inner ring (including tapered roller and cage) and outer ring can be installed separately. In the process of installation and use, the radial and axial clearance of the bearing can be adjusted, or pre-interference installation can be done. Bearings with this type include single row tapered roller bearings, double row tapered roller bearings and four row tapered roller bearings, used for a variety of industrial applications.

1.Single row tapered roller bearing

Single row tapered roller bearing can limit the axial displacement of the shaft or shell in one direction and bear the axial load in one direction. Additional axial force is generated under the action of radial load. Therefore, in the two supports of the shaft, the end faces of bearing outer ring and bearing inner ring are oppositely mounted. If used alone, the applied axial force must be greater than the additional axial force. The 313 series tapered roller bearings have large contact angles (27°~ 30°) and can withstand large axial loads. The contact angle of tapered roller bearings in other series is between 10°and 18°.

2. Double row tapered roller bearing

Double row tapered roller bearing has a pair of raceway outer ring and two inner rings, and a middle spacer between the two inner rings. The thickness of the spacer can be adjusted to adjust the bearing clearance. Double row tapered roller bearing can bear the bidirectional axial load while bearing the radial load. It can limit the bidirectional axial displacement of the shaft or shell within the axial clearance range of the bearing.

3. Four row tapered roller bearings

Four row tapered roller bearings adopt two double raceway inner rings, one double raceway outer ring and two single raceway outer rings, and there are spacers between inner ring and outer ring for adjusting clearance. It has similar performance with double row bearing: large radial load and low limit speed. Four row tapered roller bearings are mainly used for heavy machinery, such as rolling mill.
