Inch Taper Roller Bearing Description
Tapered roller bearings consist of four interdependent components: the cone (inner ring), the cup (outer ring), the tapered rollers (rolling elements) and the cage (roller retainer). Tapered roller bearings are uniquely designed to manage both thrust and radial loads between a rotating and non-rotating member. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads.

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 .
