Self-aligning ball bearing

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.
It is mainly subjected to radial loads and can withstand small axial loads. The axial displacement of the shaft (outer casing) is limited to the clearance limit, and has automatic self-aligning performance, allowing normal operation under the condition that the inner and outer sides are relatively inclined, and is suitable for the parts in which the support seat hole cannot strictly guarantee the coaxiality.
