Self-Aligning Ball Bearing have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed. Inner race is fixed and outer race can move and handle up to 3 degree. It can handle medium load capacity. The bearings are insensitive to angular misalignment up to 3 degree.

It is mostly used in blowers, power plants, conveyor system, pulleys, industrial fans, centrifugal separators, food industry separators, fan etc. Some of the good features like, it can accommodate misalignment, environment friendly, required low lubricant, exhibits low noise and low vibration level, low heat generation, high speed performance which helps for the increase in productivity.
