  The Knowledge of Spherical Roller Bearings

  Definition of spherical roller bearings The rolling elements are spherical bearings with spherical rollers. Spherical roller bearings have two rows of rollers, which mainly bear radial loads and can also withstand axial loads in either direction. There is a universal spherical raceway in the outer ring. The two inner ring raceways are inclined at an angle to the bearing center. The bearing is self-centering, so it i...
