Angular contact bearings have
one ring shoulder partially or totally removed.
This allows a larger ball complement than found
in comparable deep groove bearings, hence a greater
load capacity. Speed capability is also greater.
Angular contact bearings are assembled to a
contact angle by varying the radial clearance.
Spindle size Barden angular contact bearings have
nominal contact angles of either 15° or 25°.
The smaller angle delivers better radial capacity
and rigidity, the larger angle is better for axial
rigidity.
Separable and nonseparable types are available.
In a separable bearing (B type), the cage holds
the balls in place so that the outer ring assembly
(with cage and balls) can be separated from the
inner ring.
Separable bearings are useful where bearings
must be installed in blind holes or where press
fits are required, both on the shaft and in the
housing. The separable feature also permits dynamic
balancing of a rotating component with inner ring
mounted in place, apart from the outer ring and
housing. |
