Spherical Roller Bearings has a character of sell-aligning because the center of its raceway profile right fall on the center line of its bore diameter, even the shaft are bending slightly or the housing are inclining slightly, these errors of alignments cannot make the center of its raceway profile leave the center line of its bore diameter, this means the bearings can self-align, thus cannot produce other kinds of unnecessary strengths due to wrong alignment of shaft relative to housing. Spherical roller bearings can accommodate radial load and two directions of axial load. They suit heavy load and impact load, and are widely used in the fields such as metallurgy, mining, petroleum machinery, paper making machinery, construction machinery and large machinery.
