Self-Aligning Ball Bearings

Self-aligning ball bearing has two kinds of structure, such as the cylindrical hole and the conical hole, and the material of the retainer is made of steel plate, synthetic resin, etc.. Its characteristics are spherical raceway, with the nature of mind, can automatically adjustable to compensate concentricity and shaft deflection caused by error, but the inner and outer rings relative inclination shall not be more than 3 degrees.
