Self-aligning ball bearing has two rows of steel balls and the outer ring has an arc raceway. The bearing can automatically center and can withstand the angle error between the shaft and the bearing seat. It is suitable for working conditions prone to shaft deflection and misalignment. The friction of self-aligning ball bearings is the lowest of all rolling bearings, which makes it only have a small temperature rise in high-speed operation.
