Specification :

selfself aligning ball bearings are principally provided with two rows of symmetrical spherical rollers and a common sphere raceway in the out ring, the two inner ring raceways are included at an angle to the bearing axial .The bearings have good self-aligning ability and can operate when the shaft deflection under load or the shaftmisaligningment in mounting, and their permissible aligning angle is 1 to 2.5 degree.This type of bearings has heavy load , carrying capacity and anti-impact ability , in addition to radial loads, they alsocan carry axial loads. In the two directions, In general, this type of bearings permit a low limiting speed.
