PRODUCT SORTS：STANDARD BEARINGS
DETAILED INTRODUCTION：Angular
contact bearings are designed such that a contact
angle between the races and the balls is formed
when the bearing is in use. The major design characteristic
of this type of bearing is that one, or both of
the ring races have one shoulder relieved, or
higher than the other. In order for these bearings
to function properly, they must be assembled with
a thrust load. This loading (or preload) creates
a line of contact (or contact angle) between the
inner race, the ball and the outer race. The preload
can be built into the bearing or created when
the bearing is inserted into an assembly. The
contact angle varies from 15° to 40° and is measured
relative to a line running perpendicular to the
bearing axis. Angular contact bearings are unidirectional
thrust bearings that can withstand heavy thrust
loads and moderate radial loads.
