Overview of Self-aligning Ball Bearings
Self-aligning Ball Bearings is a kind of ball bearing with two rows of balls (called “races”). The inner ring has two raceways, and the outer ring has a spherical raceway whose center of curvature coincides with the bearing axis. In this way, the axis of the inner ring, the ball and the cage can be deflected around the bearing center, thereby automatically correcting the misalignment caused by the machining or installation errors of the bearing seat and the shaft.
They are available to be open or sealed. The bearings are insensitive to angular misalignment of the shaft relative to the housing.
Self-aligning Ball Bearings Types:
Self-aligning Ball Bearings can provide a variety of sizes, materials and varieties according to consumer needs, including special industrial uses, such as high temperature applications.
They have mainly three designs of self-aligning ball bearings: Self-aligning ball bearings-open type,Sealed self-aligning ball bearings and Self-aligning ball bearings with an extended inner ring. Depending on the application, they can also be made into different sizes and loads, from miniature ball bearings for light loads and small components to large Self-aligning Ball Bearings.
Applications of Self-aligning Ball Bearings:
Self-aligning ball bearings are particularly suitable for applications where misalignment is caused by installation errors or shaft deflection.
Due to the small axial bearing capacity, this bearing can only be used for light loads. For applications with insufficient bearing capacity (especially axial load), spherical roller bearings with the same self-aligning performance should be used.
The bearing is equipped with a pressed steel cage or polyamide cage. The suffix G with the bearing number on the packaging surface indicates a polyamide cage.
The use of Self-aligning Ball Bearings has benefited many industries:
Food and beverage
Pulp and paper Rail transport
