Spherical roller bearing can support axial forces in both directions and high radial forces. They are designed for very high load carrying capacity. Bearings with a tapered bore are also available with an adapter sleeve, locknut and tab washer or with a withdrawal sleeve.When shaft bends by force which causes the inclined between the center of inner ring and the center of outer ring,if the inclined degree not exceed 1-2.5,the bearing can work normally.
•Excellent alignment compensation
•Suitable for large radial loads
•Low to medium speed ratings
