The self-aligning ball bearing has two structures of a cylindrical hole and a tapered hole, and the material of the cage is steel plate, synthetic resin and the like. The characteristic is that the outer ring raceway has a spherical shape and has self-aligning property, which can compensate for errors caused by different degrees of heart and shaft deflection, but the relative inclination of the inner and outer rings must not exceed 3 degrees.
