Characteristics and applications of tapered roller bearings:
Conical roller bearings are mainly suitable for bearing radial and axial combined loads mainly based on radial loads, while large cone angle tapered roller bearings can be used to bear radial and axial combined loads mainly based on axial loads. This type of bearing is a separated type bearing, and its inner ring (including tapered rollers and cage) and outer ring can be installed separately. During installation and use, the radial and axial clearances of the bearings 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. 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 external axial forces are used alone, they must be greater than the additional axial forces. The 313 series bearings have a large contact angle (27 ° -30 °) and can withstand large axial loads. The contact angles of other series are 10 ° -18 °.
2. Double row tapered roller bearing (350000 type)
Note: This bearing has one outer ring and two inner rings, with a spacer ring between the two inner rings. Changing the thickness of the spacer ring can adjust the clearance, and it can withstand both radial and bi-directional axial loads. It can limit the bi-directional axial displacement of the shaft or shell within the bearing clearance range.
3. Four row tapered roller bearings (330000 type)
Note: This bearing has spacer rings 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 large load-bearing capacity and low speed limit. It is mainly used in heavy-duty machinery, such as steel mills.
