Tapered Roller Bearings have the taper track between the inner and outer ring, and have tapered rollers in the track. If extending to the tapered surface It is finally to be a point on the bearing axis. Tapered Roller Bearings mainly used for radial load to bear the main radial and axial load joint. Bearing's axial bearing capacity decided by the angle of contact that the antenna is bigger, axial bearing capacity is bigger. Taper roller bearing is the separation bearing, with the roller and in retainer's inner loop constitution the module, can separate the installment with the addendum circle.

This kind of bearing may limit the axis or the outer covering at the same time the axial translation, does not allow the axis relative shell hole to have the incline. Under the radial load function, it will have the additional axial force, so the two supporting of the bearing, bearing's addendum circle and the inner loop with various end surfaces should the relative installment.

This kind of bearing main application: Automobile front wheel, trailing wheel, transmission gearbox, differential device, pinion shaft, engine bed main axle, construction machinery, large-scale farm machinery, railroad car gear reduction unit, mill roll neck small decelerating device.
