Types of Bearings.

Magneto Type Ball Bearings:
In this type of bearings the inner ring is same to that of deep groove ball bearings but the track on outer race has one shoulder.
At the deepest position the groove track merges into the cylindrical track and therefore this bearing has a character of separable outer race.
Magneto type bearings may be loaded radially and in one direction axially, generally they are mounted in pairs and adjusted against each other with a small amount of end play. Usually these bearings are available in smaller size only.

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 15^o, 25^o,45^o
In this type of bearings contact angles between balls and tracks have been swung to an angle between 20^o to 40^o 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.
