• A shaft s finish affects frictional resistance and smoothness of travel as well as the efficiency and life of linear bearings. The lower the micron value the smoother the finish. Case hardness is a heat-treating process to harden the outside surface of shafts. Harder shafts provide more wear resistance. The higher the case value the harder
