Self-aligning Ball Bearings are duble-row non-separable
bearings with a spherical raceway in the outer ring. They are thus adjustable in an angle and shaft deflections and misalignment are permissible up to 4° from the central position. The AFK standerd production pogramme includes both cylindrical bore and taperbore self aligning ball bearings, tapered bore bearings can be mounted either directly on taperedshaft seats or on cylendrical shaft with adapter sleeves. Self aligning ball bearings with extended inner rings (series 1200 & 1300 )are sutable for mounting on solid drown shaft. with such inner ring the deviation of the bearings bore is with in tolerance class F7. Relative motion of the inner ring against the shaft is avoided by cylendrical pin which project in to a recess on one side of the inner ring if a bearing arrengment consists of two self aligning ball bearings with extended inner ring, the locking pins in the groove of the inner ring must either be put both inside or both outside the bearings arrangement.
