 The self-aligning ball bearing has two rows of balls and a common concave sphered raceway in the outer ring. The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing. It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected. Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.
We produces self-aligning ball bearings to several designs.

These are open bearings of the basic design
sealed bearings
open bearings with an extended inner ring

This type of ball bearing is recommended when alignment of the shaft and housing is difficult and the shaft may flex. The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center. Pressed steel cages are usually used. Since the contact angle is small, the axial load capacity is low. The permissible dynamic misalignment is approximately 0.*7 to 0.*2 radian (4 to 7 degrees) under normal loads.

Self-Aligning Ball Bearing
Self-aligning roller bearing has two rows of spherical rollers, the outer race is provided with a common concave spherical raceway, while the inner race is provided with two concave spherical raceways that form an angle with the bearing axis. The curvature center of the outer raceway is consistent with the bearing center.
Self-aligning ball bearings suitable for textile machines, plastic machinery, medical machinery and all kinds of industrial machinery, it is divided into two cylindrical and tapered structure (******************0), . The character is the outer ring raceway has spherical nature, with auto-Mind, to compensate concentricity and deflection errors of axis, but its inner and outer rings relative inclination not more than 3 degrees.

It also has sealed design and no longer need lubrication or maintenance Installed in the adapter sleeve and within SKF Pillow Block Bearing self-aligning ball bearings are available to customers bearing the economy configuration. 2.1 cylindrical hole aligning bearing (***0) 2.2 tapered hole aligning ball bearings (***0k type) 2.3 with adapter sleeve aligning ball bearings (***0k + H****-type).
