Grinding Direction of grinding, especially on nodular iron shafts, is important and should be in the same direction as the bearing will move relative to the shaft. Complete removal of friable or 'white' layer from nitrided journals is essential. This implies fine grinding or honing, approximately 0.025-0.05 mm (0.001-0.002 in) from surface. A11 ...
