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 .
