Product description of tapered roller bearings31313

Tapered roller bearings mainly bear combined load that are mainly from radial section and axial section. The bearing capacity depends on the angle of outside race rollaway. The angle is large the bearing capacity is large. This kind of the bearing belongs to gateless lager. According to the rows of rolling element in bearing it fall in single row, double row and four row tapered roller bearings.

Industrial application of tapered roller bearings

Tapered roller bearings apply to automobile rolling mill mine metallurgy plastics machinery etc
