самоустанавливающиеся шарикоподшипники

Self-aligning ball bearings processed into spherical outer ring raceway, aligning it with the performance. 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 afford to pure axial load, the speed limit lower than the deep groove ball bearings. This kind of bearings are used for the load prone to bending under the action of the double bearing shaft, and dual bearing seat hole can not guarantee strict concentricity of the parts, but the inner and outer ring of the center line of the relative tilt of the center line of not more than 3 ?. Such as ball and roller bearing contact area of small extent which rendered a low load capacity, life is short, and there will be self-aligning roller bearings instead of trend.
