 The  spherical roller bearing  has two rows of symmetrical spherical rollers. The rollers and the outer and inner rings 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 loading, and can support large axial loads and radial loads at the same time. SKET spherical roller bearings are mainly used in applications of following industries: mine, metallurgy, paper making and construction etc. Shown in the figures, types EA, C, CD, CA, which are designed for high load capacity, are available. Types EA, C, and CD have pressed steel cages; and type CA has machined brass cages. Type EA has especially high load capacity, features low torque, and has a high-strength cage. An oil groove and holes are provided in the outer ring to supply lubricant and the  bearing  numbers are suffixed with E4. To use bearings with oil gr...
