Tapered roller bearings are separable bearings, which are mainly used to bear combined radial and axial loads mainly based on radial loads. Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low. Tapered roller bearings can withstand axial loads in one direction and can limit the axial displacement of the shaft or housing in one direction.
The outer ring (or inner ring) of a double row tapered roller bearing is a single piece. The small end faces of the two inner rings (or outer rings) are similar, and there is a spacer in the middle, and the clearance is adjusted by the thickness of the spacer. The performance of the four-row tapered roller bearing is basically the same as that of the double-row tapered roller bearing, but it bears a larger radial load and a slightly lower limit speed than the double-row tapered roller bearing, and is mainly used for heavy machinery.
