The inner and outer rings of TRB have tapered raceways, and tapered rollers are installed between the raceways. If the tapered surface is extended, it will eventually converge at a point on the bearing axis. Tapered roller bearings are mainly used to bear combined radial and axial loads, which are dominated by radial loads. The axial load carrying capacity of a bearing is determined by the contact angle, the larger it is, the greater the axial load carrying capacity. Tapered roller bearings are separable bearings. The inner ring with rollers and cage constitutes an inner component, which can be installed separately from the outer ring. This kind of bearing can limit the axial displacement of one side of the shaft or the housing, and does not allow the shaft to tilt relative to the housing hole. Under the action of radial load, additional axial force will be generated. Therefore, generally in the two supports of the bearing, the outer ring and inner ring of the bearing should be installed opposite to each end surface. The main use of this type of bearing: automobile front wheel, rear wheel, transmission, differential, pinion shaft, machine tool spindle, construction machinery, large agricultural machinery, railroad vehicle gear reduction device, steel rolling mill roll neck small reduction device.

Sinofou inch TRB have general tolerances, and also can provide Class CL2, CL3, CL0, CL00 tolerance products according to needs.

When single-row TRB are used in pairs (the basic dimensions can be different), the additional axial force caused by the radial load must be taken into account when calculating the equivalent dynamic load of the bearing. The additional axial force S of a single-row tapered roller bearing can be calculated approximately as follows:
S=Fr/2Y
