The single-row tapered bearing has an outer ring, an inner ring assembly of which the inner ring and a set of tapered rollers are enclosed by a basket-shaped cage. The outer ring can be separated from the inner ring assembly. According to the ISO tapered bearing dimension standard, any standard type of tapered bearing outer ring or inner ring assembly should be able to achieve international interchange with the same type of outer ring or inner ring assembly. That is to say, the outer ring of the same model must comply with the ISO492 (GB307) regulations in addition to the external dimensions and tolerances, and the cone angle of the inner ring components and the diameter of the component cone must also comply with the relevant regulations for interchangeability.

Generally, the taper angle of the outer ring raceway of a single-row tapered bearing is between 10° and 19°, which can bear the combined action of axial load and radial load at the same time. The larger the cone angle, the greater the ability to bear the axial load. Bearings with large taper angle, post code plus B, taper angle between 25°~29°, it can bear large axial load. In addition, single row tapered bearings can adjust the size of the clearance during installation.
