Taper Roller Bearing Description
Tapered roller bearings are used in a variety of industrial applications. The tapered rollers allow the bearings to accommodate heavy radial, axial and combination loads. This loading flexibility combined with a variety of configurations can be designed from single cups, double cups, and cones. This is why tapered roller bearings are designed into almost every industry, particularly large diameter tapered roller bearings.

Taper Roller Bearings Applications
(1) the assembly process, to make the center line of the shaft and the bearing hole coincide. Should the tilt, installation difficulties, but will also cause indentation, journal bending, or even cause the bearing inner ring fracture.
(2) does not allow hand hammer directly beat the bearing outer ring, the inner ring.
(3) heating the assembly of a large amount of interference and medium-sized bearing should avoid bearing direct bearing contact with the oil temperature is much higher than the bottom, in order to avoid local overheating leaving the rolling element and the inner and outer ring raceways annealing lose their hardness .
