Angular Contact Ball Bearing
The Single Row Angular Contact ball bearings have higher axial load capacity than the Single Row Radial ball bearings.
The bearings can carry axial load in one direction only and are to adjusted against another bearing, if axial load is coming from both the directions. Each bearing can be located endwise in one direction only.
These bearings, when mounted in a duplex arrangement, provide axial and/or radial rigidity in applications where control of shaft displacement is essential.
Double Row Angular Contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate and simultaneously action axial and radial loads. Due to angular contact 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 load is transmitted from one raceway to another, and a line perpendicular to the bearing axis. These bearings can accommodate thrust in both the directions. The chief advantages of the double row type are rigidity, compactness and high capacity.
