Tapered roller bearing is mainly applicable to bear radial and axial joint load based on radial load. But steep angle tapered roller bearing 

can be used to bear radial and axial joint load based on axial load. This type of bearing is separable bearing, the inner ring 

(including tapered roller and cage) and the outer ring of which can be installed separately. The radial clearance and axial clearance can be 

adjusted in the process of installation and using, or can be installed with pre-interference.

Single row taper roller bearing is mainly endured united load of radial and axial direction and not suitable to endure independently axial load 

and it is not allowed axial shell empty with slope. It will come into additional to use in pairs.

Taper roller bearings are mainly used in auto-motives, rolling mill, mining, metallurgy, plastic,slowdown machine and etc.
