High Quality self-aligning ball bearing 1211

Self-aligning ball bearing has two rows of steel balls, a inner ring that has two raceways and a outer raceway in the inner spherical shape, and is provided with the function of self-aligning. The bearing can automatically compensate the concentricity error caused by the shaft deflection and housing deformation, thus suitable to the applications where the bearing seat hole can not guarantee strict concentricity. so it can still works as long as the relevant gradient between the center line of the inner ring and the same of the outer ring is within the range of 1 ° to 2.5 ° when the shaft is bent or tilted under pressure. There are two types of self-aligning ball bearings, i.e., cylindrical bore and tapered bore bearings. The taper ratio of tapered bore bearings is 1:1 or 1:30.

Self-aligning ball bearings are mainly used to carry heavy loads and impact loads, and apply to industries such as mining, petroleum, paper making, cement, sugar pressing, etc. and general machinery including precision instruments, low-noise motors, automobiles, motorcycles, rolling mills, etc.

high precision Self-Aligning Ball Bearing

With the same center as the bearing, self-aligning ball bearing formed outer ring raceway can make self-alignment. Their rolling elements linearly come into contact with the raceways of inner ring and outer ring. The self-aligning Bearings can take great radial load.
