Self-aligning ball bearing is constructed with the inner ring and ball assembly contained within an outer ring that has a spherical Self-aligning ball bearing has two rows of balls. Bearings’ spherical raceway whose center of curvature accords with the bearing center. Even through the inner race, the steel balls and the holder incline relative to the outer race, the bearing can rotate. 

Self-aligning ball bearings’ sphere raceway in the outer ring and a double raceway in the inner ring, which gives self-aligning ball bearings their self-aligning property, permitting angular misalignment of the shaft relative to the housing. Therefore, when the deflection between shaft and housing happens, we need to use self-aligning ball bearing to reduce the load of the bearing by rectifying the angular misalignment, as the spherical raceway of the outer ring allows the balls together with the cage and inner ring rotate in either direction.

Self-aligning ball bearing have two kinds of structure: cylindrical hole and conical hole, which are generally use heavy pressure cages made of steel plate, synthetic resin, etc., and generally can be divided into:

(1) Mini-series 10x、12x、13x

(2) General Series 12xx、13xx、22xx、23xx

Self-aligning ball bearing have the features and benefits of high adaptability to both dynamic and static misalignment, Low friction, less heat and noise, allowing it to run at high speed, then the lifetime is prolonged accordingly and lessens the maintenance intervals, which particularly suitable for applications where misalignment can arise from errors in mounting or from shaft deflection. which are mainly used in precision instrument, low noise motor, motor, motorcycle and general machinery, etc. It is the most widely used kind of bearing in the machinery industry.
