Single row tapered roller bearings
Single row tapered roller bearings can bear axial load in one direction. And can limit the axial displacement of the shaft relative to the bearing seat in one direction. Even under the action of pure radial load, the tapered roller bearing will generate additional axial component force inside. At this time, an equal amount of reaction force is required to balance it. Usually two single-row tapered roller bearings of the same structure are used in the two supports to face-to-face or back-to-back installation.
