self-aligning ball bearing

Self-aligning ball bearings have two types of structures, cylindrical hole and tapered hole, and the materials of the cage include steel plate, synthetic resin, etc. Its characteristic is that the raceway of the outer ring is spherical and has self-aligning properties, which can compensate errors caused by different concentricity and shaft deflection, but the relative inclination of the inner and outer rings must not exceed 3 degrees.

The center of curvature of the raceway surface of the outer ring is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and shell are deflected, it can be adjusted automatically without increasing the burden on the bearing. Spherical roller bearings can bear radial loads and axial loads in two directions. Large radial load capacity, suitable for heavy loads and impact loads. The inner diameter of the inner ring is a bearing with a tapered hole, which can be directly installed. Or use an adapter sleeve or a dismounting cylinder to install on a cylindrical shaft. The cage uses steel stamping cage, polyamide forming cage and copper alloy car cage.
