There are two rollers in the Self-Aligning Ball Bearing inner circle, which show the sphere, and the center of curvature of the sphere is consistent with the bearing center. Therefore, the inner circle, ball and holder, the outer circle can tilt relatively freely. Therefore, the deviation due to the processing error of the case can be automatically adjusted.

Self-Aligning Ball Bearing has two structures: cylindrical hole and conical hole, and the material of the holder is steel plate, synthetic resin, etc. It is characteristic that the outer circle roller is spherical with automatic centricity, which can compensate for the errors caused by different centricity and axial deflection, but the relative inclination of the inner and outer circles shall not exceed 3 degrees.

Deep groove ball bearing with dust cover and seal ring has been filled with proper grease, should not be heated or cleaned before installation, no relubrication to accommodate the operating temperature between – 30 ℃ and + 120 ℃.

The Self-Aligning Ball Bearing inner ring, ball and holder can rotate freely around the center of the bearing, with icity. Its centering ability can compensate for the medium error, shaft deformation and bearing seat deformation. Self-Aligning Ball Bearing is suitable for the shaft and the central housing, flexible shaft.

Self-Aligning Ball Bearing is a double – column ball bearing processed by outer circle roller into spherical shape with two deep groove rollers in inner circle with heart tuning performance. It is mainly used to bear the radial load, while bearing the radial load, it can also bear a small amount of axial load, but generally can not bear the pure axial load, its ultimate speed is lower than the deep ditch ball bearing. This kind of bearings are mostly used on the double bearing shaft prone to bending under the load, and the double bearing hole can not guarantee the strict coaxial components, but the relative tilt of the inner ring center line and the outer coil center line shall not exceed 3 degrees. It is suitable for bearing heavy load and impact load, precision instrument, low noise motor, automobile, motorcycle, metallurgy, mill, mines, oil, paper, cement, sugar pressing and general machinery, etc.
