Tapered roller bearings, characteristics and uses:
The tapered roller bearings to withstand the radial load mainly radial and axial load, the large cone angle tapered roller bearings can be used to withstand the axial load mainly radial, axial joint load. Such bearings are separable type bearings, the inner ring (including tapered roller and cage) and the outer ring can be installed separately. Bearing radial clearance and axial clearance can be adjusted in the process of installation and use, can also be preloaded mounting.
Specific classification and models of control:
A single row tapered roller bearings (30000 type)
Note: You can withstand the radial load mainly radial and axial load, the large cone angle bearings can withstand axial load mainly radial, axial load, additional axial force in the radial loads, Therefore, generally in pairs configuration can withstand the radial load, used alone, the applied axial force must be greater than the additional axial force, the 313 series bearings have a large contact angle (27 ° -30 °), can withstand greater axial load The other series contact angle 10 ° -18 °.
2, the double row tapered roller bearings (350000 type)
Note: an outer two inner ring of the bearing, a spacer between the two inner, changing the thickness of the spacer to adjust the clearance, radial load and bi-directional axial load within the scope of the bearing clearance limit the bi-directional axial displacement of the shaft or housing.
Three, four tapered roller bearings (330000 type)
Note: The bearing between the inner and outer rings are used to adjust the spacer clearance, performance and double row tapered roller bearings are basically the same, large carrying capacity, speed limit, mainly for heavy machinery, such as rolling mill etc.
