Self-aligning ball bearing outer ring raceway is spherical, the curvature center and bearing center consistent. Therefore, inner ring and ball and cage can rotate freely around the bearing center, with the mind. Suitable for shaft and the shell of center difficult, axis deflection of the shaft is seen. Because the contact Angle is small, so the axial load capacity is small. General use stamping cage.

Self-aligning ball bearing allows self-aligning Angle, under the condition of normal load, is about 0.07 ~ 0.12 radians (4 to 7 degrees). According to bearing around on installation size, there are short of the special case of the self-aligning Angle, please note.
