Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis....
With the same centre as the bearing, the spherically formed outer ring raceway can make self alignment, their rolling elements linearly come to contact with the raceways of inner ring and outer load, suitable for heavy machinery used in mining....
Features : Accommodate misalignment. High load carrying capacity. Relubrication features. Low friction and long service life. Increased wear resistance.
