NTN Bearing 2308C3 Double Row Self-Aligning Radial Ball Bearing, C3 Clearance, Steel Cage, 40 mm Bore ID, 90 mm OD, 33 mm Width, Open

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. Self-aligning bearing for applications subject to shaft deflections or misalignments between the shaft and housing Straight bore for fitting on a conventional cylindrical shaft Steel cage evenly spaces balls for reduced friction, vibration and noise Open bearing for lubrication applied in place C3 radial clearance allows thermal expansion for continuous operating temperatures up to 120 degrees C/248 degrees F
