NTN 1211K Double Row Self-Aligning Ball Bearing - Tapered Bore, Steel Cage, 55mm ID x 100mm OD x 21mm Width - for Industrial Machinery, Conveyors, and Heavy Equipment Maintenance

Double row self-aligning bearings utilize an inner ring with two rows of balls in two deep raceways, and an outer ring with a single spherical raceway. In this way, the inner and outer rings can be misaligned relative to each other. The resulting effect is a comparatively large angle imposing moment loads upon the balls. The boundary dimensions of the 1200 and 1300 series are the same as the 6200 and 6300 single row deep groove bearings.NTN is one of the three largest bearing companies in the world with more than ninety years of manufacturing expertise in ball bearings.
