Single row tapered roller bearings
1. Rated dynamic load ratio 1.5～2.5
2. Able to withstand unidirectional axial load, additional axial force will be generated under the action of radial load, generally used in pairs
3. Able to limit axial displacement of shaft and housing in one direction
4. low speed limit
The 313 series has a larger contact angle and can withstand larger axial loads. The contact angle of other series is between 10°～18°
Double row tapered roller bearings
1. Rated dynamic load ratio 2.6～4.3
2. While bearing radial load, it can bear bidirectional axial load
3. Limit the axial displacement of the shaft and housing within the axial clearance range
4. limit speed
Changing the thickness of the spacer can adjust the radial clearance of the bearing
Four row tapered roller bearings
1. The bearing capacity is very large, and the rated dynamic load ratio is 4.5 to 7.4
2. Can withstand large bidirectional axial loads
3. Limit the axial displacement of the shaft and housing within the axial clearance range
4. low speed limit
The radial clearance of the bearing can be adjusted by changing the thickness of the spacer. Mainly used for heavy machinery, such as rolling machinery.
