Tapered roller bearings feature
Tapered roller bearings feature tapered inner and outer ring raceways with tapered rollers arranged between them, angled so the surface of the rollers converges at the axis of the bearing.
Tapered roller bearings can usually be broken down into separate parts. The inner ring with a roller and cage assembly can be removed and mounted separately from the outer ring.
A single row taper bearing is limited in that it can only take high axial loads from one direction, but if adjusted against a second tapered roller bearing, that axial load is counteracted. This allows the bearings to accept high radial and axial loads from multiple directions.
The ability of a tapered roller bearing to accommodate angular misalignment of the inner ring in relation to the outer ring is limited to a few minutes of arc. As with other roller bearings, tapered roller bearings must be given a minimum load, especially in high-speed applications where the inertial forces and friction can have a damaging effect between the rollers and raceway.
The angle of the outer ring and the outer race diameter has been standardized as the outer dimensions. Changes are not allowed at the time of design and manufacture. So that the outer ring of the tapered roller bearing and the inner component can be universally interchanged worldwide.
Tapered roller bearings are mainly used to withstand radial and axial combined loads based on radial loads. Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low. Tapered roller bearings are capable of withstanding axial loads in one direction and can limit axial displacement in one direction of the shaft or housing.
