TAPER ROLLER BEARING

Tapered roller bearings are mainly applied to radial and axial joint loads which bear radial load, while large cone angle tapered roller bearings can be used to bear the joint load of axial and axial loads. The bearing is a separate bearing, and its inner ring (including tapered roller and cage) and outer ring can be installed separately. During installation and operation, radial clearance and axial clearance of bearings can be adjusted, and pre interference installation can also be made.
The single row tapered roller bearing 30000 can restrict the axial displacement of the shaft or shell in one direction and bear the axial load in one direction. Additional axial force will be generated under the action of radial load. Therefore, in the two support of the shaft, the outer ring of the bearing and the same end of the inner ring of the bearing are relatively installed. If used alone, the external axial force must be greater than the additional axial force.
Double row tapered roller bearing 350000, with a double raceway outer ring and two inner rings, two inner ring has a circle, changing the width of the diaphragm can adjust the clearance of the bearing. The bearing can bear two-way load while bearing radial load. It can restrict the bidirectional displacement of the shaft or shell in the axial clearance range of the bearing.
Four row tapered roller bearing 380000, the bearing adopts two double roll inner ring, a double roll channel outer ring and two single roll outer ring, and the inner ring and outer ring are used to adjust the gap. Its performance is the same as that of double row tapered roller bearings, and it can bear large radial load, but the limit speed is low. It is mainly used for heavy machinery, such as rolling mills.
The size of the axial clearance of tapered roller bearings has great influence on whether the bearing can work well. When the shaft clearance is too small, Wen Shenggao, when the axial clearance is too large, the bearing is easy to damage. Therefore, during installation and operation, special attention should be paid to adjusting the axial clearance of bearings. The clearance between double and four row tapered roller bearings produced by wa Ye shaft has been given at factory time without user adjustment.
