Spherical roller bearings
Spherical roller bearings are high-capacity self-aligning bearings with barrel-shaped rolling elements. These bearings have two rows of rolling elements and a common sphered raceway on the outer ring. They can accommodate shaft misalignment relative to the housing. Spherical roller bearings can carry radial loads, but also heavy axial loads in both directions. Standardly, we distinguish double-row spherical roller bearings, but also single-row ones.
