5215 bearing

Angular contact ball bearings have raceways on the inner and outer rings, and the inner and outer rings can move relative to each other along the bearing axis. This type of bearing is particularly suitable for bearing compound loads, that is, loads acting simultaneously in the radial and axial directions. The axial load bearing capacity of angular contact ball bearings increases with the increase of contact angle α. The contact angle is the angle between the line connecting the contact points of the ball and the raceway in the radial plane and the vertical line of the bearing axis.
