Self-aligning ball bearings have two rows of balls, a commonly sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed. The bearings are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.
The axial load carrying capacity of SKF Self-aligning Ball Bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.
The SKF bearing catalog lists a large range of designs, variants, and sizes of SKF Self-aligning Ball Bearings. Beyond our catalog offering, the TFL SKF Self-aligning Ball Bearings can also be customized to provide advantages for applications with specific performance requirements.
