Self aligning ball bearings

Double-row deep groove ball bearings are similar with single-row bearings in design and have no ball-loading gaps, so they can withstand axial loads in both directions.
Product description

Self-aligning ball bearings








Mainly bear radial load, and can bear small axial load at the same time. It has self-aligning performance, can work normally when the inclination angle is not large.




Technical Performance:


Self-aligning ball bearings are bearings with steel balls and cage assemblies between the two raceways inner ring and spherical raceways outer ring. Self-aligning ball bearing has two structures of cylindrical hole and conical hole. The material of the cage is steel plate, synthetic resin, engineering plastic and so on. The self-aligning ball bearing can have sealing structure similar to the deep groove ball bearing, but it will affect the self-alignment of the bearings.


Self-aligning ball bearings mainly bear radial load, and can bear small axial load at the same time. It can’t bear pure axial load. Due to the structure, the limit speed of self-aligning ball bearings is relatively low. Since the curvature center of the raceway surface of the outer ring is the same as the center of the bearing, it has the self-aligning function, which can compensate for the errors caused by the misalignment and the deflection of the shaft and the outer casing, but the relative inclination of the inner and outer rings should not exceed 3 degrees. This type of bearing is mostly used on double support shafts that are prone to bending under load, and in components where the housing seat hole cannot be strictly coaxial.


Our self-aligning ball bearing products are available in a variety of constructions, including general-purpose open type and sealed type with high-quality lubricants.









Main Applications

Metallurgy, rolling mill, mining, petroleum, paper, cement, textile, sugar extraction and other industries and general machinery.
