Taper roller bearing

Characteristics and Applications of Conical Roller Bearings:
Conical roller bearings are mainly suitable for bearing radial and axial combined loads with radial loads as the main load, while large cone angle conical roller bearings can be used to bear radial and axial combined loads with axial loads as the main load. This type of bearing is a separable bearing, and its inner ring (including tapered rollers and cage) and outer ring can be installed separately. During installation and use, the radial clearance and axial clearance of the bearing can be adjusted, and pre interference installation is also possible.
Specific classification and model comparison:
1. Single row tapered roller bearing (30000 type)
Note: It can withstand radial and axial loads mainly based on radial loads, and large cone angle bearings can withstand radial and axial loads mainly based on axial loads, generating additional axial forces under radial loads. Therefore, they are generally configured in pairs and can withstand radial loads. If used alone, the additional axial force must be greater than the additional axial force. The 313 series bearings have a large contact angle (27 ° -30 °) and can withstand large axial loads, while other series have a contact angle of 10 ° -18 °.
2. Double row tapered roller bearing (350000 type)
Note: This bearing has an outer ring and two inner rings, with a spacer between the two inner rings. By changing the thickness of the spacer, the clearance can be adjusted, and it can withstand both radial and bidirectional axial loads simultaneously. It can limit the bidirectional axial displacement of the shaft or housing within the bearing clearance range.
3. Four row tapered roller bearing (330000 type)
Note: This bearing has spacers between the inner and outer rings for adjusting clearance, and its performance is basically the same as that of double row tapered roller bearings. It has a high load-bearing capacity and low speed limit, and is mainly used in heavy machinery such as rolling mills.
