In 1919, SKF invented the spherical roller bearing. SKF has continued to further develop and refine the design, including the way it is sealed. The best proof of the total quality of SKF spherical roller bearings is their success. Twice as many SKF spherical roller bearings are used today as those of any other bearing manufacturer.
