Self-aligning ball bearing is between the inner ring of two raceways and the outer ring of a spherical raceway. The center of curvature of the raceway surface of the bearing outer ring equipped with spherical ball bearings is consistent with the center of the bearing, so it has the same self-aligning function as the automatic self-aligning ball bearing.

When the shaft shell is bent, it can be automatically adjusted without increasing the bearing burden Spherical roller bearings can bear radial load and two direction axial load radial load capacity is large, suitable for heavy load impact load conditions Inner circle diameter is tapered bore the bearing, it can remove the cylinder to install or use the set of bracket will be installed on the cylinder axis using steel plate stamping maintains a polyamide forming keep frame and copper alloy cage car system.

Self-aligning ball bearings have cylindrical holes and conical holes two kinds of structure, cage material has steel plate, synthetic resin and so on. The raceway of the outer ring is spherical and has automatic centering, which can compensate the errors caused by different concentricity and shaft deflection, but the relative inclination of the inner and outer rings shall not exceed 3 degrees.
