Tapered roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at a common point on the bearing axis. Their design makes tapered roller bearings particularly suitable for the accommodation of combined (radial and axial) loads. The axial load carrying capacity of the bearings is largely determined by the contact angle; The larger angle, the higher the axial load carrying capacity.

Tapered roller bearings are commonly used in automobile(front wheel, rear wheel, transmission, differential pinion shaft), machine tool spindle, building machinery, large-scale agricultural machinery, gear reduction unit of the railway vehicle, etc. Tapered roller bearings have many designs and sizes to match their widely uses:

----single row tapered roller bearings(fig1)

----paired single row tapered roller bearings(fig2)

----double row tapered roller bearings(fig3)

----four-row tapered roller bearing(fig4)
