Aaaaa-aligning ball bearing NTN
-aligning ball bearing outer ring raceway processed into spherical, it has a self-aligning properties. Mainly used to bear radial load, radial load at the same time, it can withstand a small amount of axial load, but generally can not bear the pure axial load, its speed limit lower than the deep groove ball bearings. This kind of bearings are used for the load prone to bending under the double bearing shaft, and double bearing seat hole can not guarantee strict concentricity of the parts, but the inner ring and outer ring center line center line of the phase misalignment more than 3. Kind of ball and roller bearings because of the small contact area that may cause the load capacity is low, life is short, and there will be self-aligning roller bearings instead of the trend.
