How Ball Bearing Works? Tell You the Operating Principle
Ball Bearing can be separated into inner ring、outer ring、retainer and balls:. Inner Ring - It's the rotating element, stuck with the axis, and rotates with the axis.; Outer Ring - On the outer ring, there's a groove on its inside surface, It's the pathway for the balls；meanwhile, It's also a supporting role.; Retainer - Separate balls, and avoid balls falling out of the bearing.
