Spherical Roller Bearings provide low-friction rotation as well as angular misalignment. These bearings are suitable for operating even with large misalignment between the inner and outer rings. Spherical roller bearings are designed with two rows of rollers, allowing them to withstand extremely high radial and axial stresses in any direction.
They can be symmetrical or asymmetrical; the rollers are manufactured dimensionally and geometrically, with very precise tolerances almost identical in a roller set. The symmetrical rollers self-adjust, providing optimal load distribution along the roller length and, together with the special profile, prevent edge stress from occurring at the roller ends. They are commonly found in Industrial Gearboxes, Conveyors, Cement Grinding Rolls, or Sugarcane crushers. Also, in the wind industry as main bearings.
