The raceway of the outer ring is spherical, and the center of curvature is consistent with the center of the bearing. Therefore, the inner ring, the ball, and the cage can rotate freely around the center of the bearing and have self-aligning properties. It is suitable for transmission shafts where the shaft and housing are difficult to center and the shaft is prone to flexure. Because of the small contact angle, the axial load capacity is also small. Generally, stamping cages are used.
The permissible alignment angle of the self-aligning ball bearing is about 0.07～0.12 radians (4-7 degrees) under normal load conditions. According to the relevant installation dimensions around the bearing, there are special cases where this adjustment angle cannot be achieved, so please pay attention.

Spherical roller bearing Application
Spherical bearings are used in countless applications, wherever rotational motion must be allowed to change the alignment of its rotation axis. A prime example is a tie rod on a vehicle suspension. The mechanics of the suspension allow the axle to moveup and down, but the linkages are designed to control that motion in one direction only and they must allow motion in the other directions. Spherical bearings have been used in car suspensions, driveshafts, heavy machinery, sewing machines, and many other applications.
