The ability of a single row tapered roller bearing to withstand axial loads depends on the contact angle, which is the angle of the outer raceway. The larger the angle, the greater the axial load capacity. The most commonly used tapered roller bearing is the single row tapered roller bearing. In the front wheel hub of the sedan, small-sized double row tapered roller bearings are used. Four row tapered roller bearings are used in heavy machinery such as large cold and hot rolling mills.

A single row tapered roller bearing has an outer ring, and its inner ring and a set of tapered rollers are enclosed by a basket shaped cage to form an inner ring component. The outer ring can be separated from the inner ring component. According to the ISO standard for the external dimensions of tapered roller bearings, any standard model of tapered roller bearing outer ring or inner ring component should be able to achieve international interchangeability with the same model of outer ring or inner ring component. The outer ring of the same model must comply with ISO492 (GB307) regulations for external dimensions and tolerances, and the cone angle and cone diameter of the inner ring components must also comply with relevant regulations for interchangeability.

Usually, the cone angle of the outer raceway of a single row tapered roller bearing is between 10 ° and 19 °, which can simultaneously withstand the combined action of axial and radial loads. The larger the cone angle, the greater the ability to withstand axial loads. The bearing with a large cone angle, with the suffix B, has a cone angle between 25 ° and 29 °, and can withstand large axial loads. In addition, the clearance of single row tapered roller bearings can be adjusted during installation.

Taper roller bearings are widely used in industries such as automobiles, rolling mills, mining, metallurgy, and plastic machinery.
