Self-Aligning Ball Bearing 2200 Series
Double row 2200 series 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.
This bearing design utilizes two rows of balls with the inner ring having two deep groove raceways. The outer ring has a single continuous spherical raceway. This permits the inner and outer ring to be misaligned relative to each other through a comparatively large angle. This process doesn't impose moment loads upon the balls. This bearing is frequently used when the inner ring is to be mounted upon an adapter sleeve. It can also be used when conditions in the machine make it difficult to ensure alignment of the inner and outer rings.
Application
Self-aligning ball bearings are suitable for bearing heavy and shock loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, papermaking, cement, sugar pressing and other industries and general machinery.
