About Self-aligning Ball Bearing
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 0.07 to 0.12 radian. (4 to 7 degrees) under normal loads.
Self aligning ball bearings are non separable double-row radial bearings:
Series: 1200, 1300, 2200, 2300, 11200, 11300
Product features: mainly bear radial load, at the same time can bear small axial load. The axial displacement of the shaft (shell) is limited within the clearance limit, with automatic self-aligning performance, allowing the normal work under the condition of relatively small inclination inside and outside, suitable for supporting seat holes can not strictly ensure the coaxiality of the parts.
Main applications of self-aligning ball bearing:
low noise motor, automobile, motorcycle, woodworking machinery, transmission shaft of textile machinery, mining machinery, mechanical and electrical equipment, plastic machinery, work equipment, medical equipment, fitness and sports equipment and general machinery, etc.
