The single row tapered roller bearing has an outer ring, its inner ring and a set of tapered rollers are enclosed by a basket-shaped cage to form an inner ring assembly. The outer ring can be separated from the inner ring assembly. According to the tapered roller bearing outline dimension standard, the outer ring or inner ring assembly of any standard type of tapered roller bearing should be able to achieve international interaction with the outer ring or inner ring assembly of the same model change.
Generally, the tapered angle of the outer ring raceway of a single-row tapered roller 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 withstand axial load. Bearings with large taper angle, add B to the rear code, and the taper angle is between 25° and 29°, and it can bear larger axial loads. In addition, single row tapered roller bearings can adjust the size of the clearance during the installation process.
