Tapered roller bearing can be separated, the inner ring and roller, cage of outer together components and can be installed respectively. Roller and roller way contact place fixed contact line can reduce stress concentration. Tapered roller bearing can bear large radial load and axial load. Because of cone roller bearing can only transfer unilateral axial load, therefore, in order to transfer the opposite direction of the axial load will need another symmetric installed circular cone roller bearings.

Tapered roller bearing is the largest amount of single row circular cone roller bearings. In the car wheel hub, in recent years is also played by the small size of the double row circular cone roller bearings. Four row circular cone roller bearings used in large cold, hot rolling mill and other heavy machine.

Tapered roller bearing classification

Single row circular cone roller bearings have a case and its ring and a set of tapered roller by basket shape cage cover into an inner ring components. Outer and inner ring components can be separated, according to ISO tapered roller bearing external dimensions standard regulation, any a standard type of tapered roller bearing's outer or inner ring components should be able to and the outer or inner ring components and implementation of international exchange. That is the outer of except external size, tolerance must be in accordance with ISO492 (GB307) specified, inner ring component cone Angle, component cone diameter and so on also must comply with the relevant provisions of the exchange.

Usually, the single row circular cone roller bearing's outer raceway of cone Angle in 10 ° ~ 19 ° before, can also bear bearing axial load and radial load of joint action. Cone Angle, the greater the bear axial load ability also more. Big cone Angle of the bearing, rear code and B, cone Angle at 25 ° ~ 29 ° between, it can bear the larger axial load. In addition, single row circular cone roller bearings can be in the installation process adjustment windage size.

Double row circular cone roller bearing housing washer (or inner ring) is a whole. Two inner ring (or outer) small face similar, and there is a baffle, clearance is to rely on the thickness of the baffle to adjust, can also be used to adjust the thickness of the baffle double row circular cone roller bearing preliminary interference.
