Angular Contact Bearing

1. 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. The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. 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. 
3. Single row angular contact ball bearings can carry axial load acting in one direction only. Single row angular contact ball bearings can accomodate radial and thrust loads. 
4. Angular contact ball bearings features: 
1) Load capacities are higher than deep groove ball bearings of same dimensions 
2) Used for bearing radial-axial combined loads or pure thrust loads 
3) Low operating friction and high limiting speed 
6. Mounting 
/DB: Mount in duplex, back to back 
/DF: Mount in duplex, face to face 
/DT: Mount in duplex, tandem 
7. Internal structure: 
C: Normal contact angle a=15 
AC: Normal contact angle a=25 
B: Normal contact angle a=40
