Angular Contact Ball Bearings:-
Angular contact bearings are single row ball bearings but designed
in such a way that the central line of the contact between balls and race ways
is at an angle. This angle is called a contact angle and as per the
manufactured design these vary between 15o, 25o,45o.
In this type of bearings contact angles between balls and tracks have been
swung to an angle between 20o to 40o to the radial plane.
These bearings are capable of carrying higher axial loads than the
corresponding deep groove ball bearings, but in one direction only. These
bearings are eminently suitable where heavy thrust loads are encountered at
high speeds.
Usually these bearings are mounted in pairs and adjusted axially against each
other so that they may support combination of heavy radial and thrust loads.
Double Row Angular Contact Ball Bearings:-
The design of these bearings corresponds to a pair of single row angular
contact. These bearings are available either with no axial play or with limited
amount of axial play.
Double row angular contact bearings are characterized by a high load carrying
capacity. They can carry substantial amount of radial load as well as axial
load. These bearings are particularly suitable where rigid axial location of
rotating mechanism is necessary.
