Handbook of Machining with Grinding Wheels

The abrasive used for each succeeding grinding operation should be one or two grit sizes smaller than that used in the preceding step. A satisfactory fine grinding sequence might involve SiC papers with grit sizes of 240, 320, 400, and 600 grit [P280, P400, P800 and P1200]. This sequence is used in the "traditional" approach.

Certain rear wheel bearings use the axle as an inner race; that is the bearing rollers ride directly on the axle shaft itself. At times, worn or pitted rollers, chipped or damaged bearings can wear a groove into the axle shaft. (See Fig. 1) Over time, the seal may also wear a groove into the axle shaft.
