Double row tapered roller bearings
The ability of single-row tapered roller bearings to bear axial load depends on the contact angle, that is, the outer ring raceway angle. The greater the angle, the greater the axial load capacity. The most used tapered roller bearings are single row tapered roller bearings. In the front wheel hub of the car, a small-sized double-row tapered roller bearing is used. Four-row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills.

Double row tapered roller bearings
Tapered roller bearings refer to radial thrust rolling bearings with tapered rollers. There are two types: small cone angle and large cone angle. The small cone angle mainly bears the combined radial and axial load based on the radial load. It is often used in double use and reverse installation. The inner and outer races can be installed separately. The radial and axial clearances can be adjusted during installation and use; The large taper angle mainly bears the combined axial and radial load based on the axial load. Generally, it is not used to bear the pure axial load alone, but can be used to bear the pure radial load when configured in pairs (the ends of the same name are installed relative to each other).
