Double-row Spherical Roller Bearings

The self-aligning roller bearing has two rows of symmetrical spherical roller. The roll and the outer and inland circle have the same shape. When the bearing was deformed and the error concentric between bearing and bearing frame will be occurred, this bearing can mend the decline about 0.5° -2° . This bearing has high radial loads, and can support large axial loads and radial loads at the same time. To the different load and speed, the various serious bearing can be chosen, and mainly used in the applications of follow industries: mine, metallurgy, papermaking and construction etc.
