127 Miniature Self-aligning Ball Bearing Size 7x22x7mm Made in China High Quality Cheap Price

The components of the self aligning ball bearing include two rows of balls, a cage, an inner ring, and an outer ring with a common concave sphered raceway.This type of bearings is self-aligning and insensitive to angular misalignments of the shaft relative to the housing. The bearings are produced in several design: open bearings with the basic design, sealed bearings, open bearings with an extended inner ring.The self alignning ball bearings have the lowest friction of all rolling bearings.The bearings are available with a cylindrical bore or with a tapered bore in certain size ranges. Self-aligning ball bearings have two rows of balls and a common concave sphered raceway in the outer ring. The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing. It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected. Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.

Aligning ball bearings are widely applied to heavy loads and shock load, precision instruments, low noise motors, automobiles, motorcycles, metallurgy, mill, mining, petroleum, paper, cement, squeezed sugar industry and general machinery.
