It doesn't increase the harness of the surface at all, it just produces a residual compressive stress on the surface that will increase the fatigue strength of the part. The ultimate and yield strengths of the part WILL NOT be increased. Usually, this will cause the part to twist to some extent, so pulling a few tenths off the big end is not a bad idea if you have confidence in the fixture and equipment your machine shop is using.MotoFool said:
what they do is basically a proces of shooting lead or shot at the rods to crush the outer layer down and harden the metal that has nothing to do with bearing sizes..

you beat me to it...shot peening also reduces surface stresses through the reduction of surface flaws....sort of like a rough polishing.turbotoy said:It doesn't increase the harness of the surface at all, it just produces a residual compressive stress on the surface that will increase the fatigue strength of the part.
