The inner and outer rings of tapered roller bearings are tapered, and the rollers are also tapered. It is a separable bearing, and the inner component of the bearing (composed of a roller, a cage and an inner ring) and the outer ring can be separated. Therefore, it can be easily installed on the journal and bearing seat. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed. Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
Single Row Type:
Single-row tapered roller bearings can withstand axial loads in one direction. And can limit the axial displacement of the shaft relative to the bearing seat in one direction. Tapered roller bearings even under the action of pure radial load, there will be additional axial component force inside, at this time, there needs to be an equal amount of direction action to balance with it. Two single-row tapered roller bearings of the same structure are usually installed face to face or back-to-back to each other in two supports.
