It is confirmed that by improving the surface roughness of the raceways, the liferating of the bearings can be increase up to double its actual value. Therefore the super-finishing of the raceways on our ball and roller bearings is aimed to optimize the bearing performance.  The super-finishing process, besides giving to the surface a low roughness, improves the form tolerances of roundness, waviness, flatness, cylindricity and compensate profile errors on the parts.
