Wide inner ring type

The wide inner ring type self-aligning ball bearing is a classic practical model of self-aligning ball bearing. The core is designed with widened inner ring on the basis of standard self-aligning ball bearings, retaining the self-aligning core characteristics of double row steel balls and outer ring spherical raceways. At the same time, by widening the inner ring, the contact area with the shaft is improved, the connection rigidity and positioning stability are enhanced, and it is suitable for light medium load conditions such as thin shaft diameter, large installation coaxiality deviation, and strong shaft system fixation. It is a highly adaptable support choice for general industrial scenarios such as textile machinery, conveying equipment, agricultural machinery, and motor end caps. It is also one of the most widely used derivatives of self-aligning ball bearings.
