Angular contact ball bearings : the axial load carrying capacity of angular contact ball bearings
increases as the contact angle increases. The contact angle is
defined as the angle between the line joining the points of contact
of the ball and the raceways in the radial plane, along which the
combined load is transmitted from one raceway to another, and a
line perpendicular to the bearing axis.
Angular contact ball bearings Types :
- Single row angular contact ball bearings
- Double row angular contact ball bearings
- Four-point contact ball bearings
- Super-precision angular contact ball bearings
- Double row cam rollers
- Hub bearing units
