Characteristics of self aligning ball bearing

The raceway surface of the outer ring is spherical and has the function of centering. This kind of bearing is suitable when the shaft and the seat hole are not concentric due to processing, installation and shaft bending. The deflection angle can be adjusted within 3 °.

The contact angle of the bearing is small, almost unchanged under the axial force, and the axial bearing capacity is small.

It mainly bears radial load, while bearing radial load, it can also bear a small amount of axial load, and its limit speed is lower than that of deep groove ball bearing.
