Tapered roller bearing is designed in such a way that cone paexes of inner ring raceway,outer ring raceway and roller raceway intersects at one point of its central line.Beside metric series products,there are inch series products,which are applicable for heavy load and impact load.

1,Single row tapered roller bearing

It can bear simultaneously radial load and single row axial load.

When carrying radial load,it creates axial thrust load.Thus two bearings are configured (or combined)face to face or back to back.

According to contact angle difference,it is classified into three types:small come angle, medium cone angle and big cone angle.

2,Double row tapered roller bearing

It is classified into two types:capped and open.

The former equips two raceway outer rings and two single raceway inner rings.The latter equips two raceway outer rings and one double raceway inner ring.Both of them can bear radial load and double row axial load.In order to make bearing having required internal clearance after eing installed,its inner/outer spacer are thinned preciously.
