Hi to all, I have recently discovered that using glass bead (H) at 100 psi suction fead with a 3/8" nozzle has been distorting a bearing.The bearing is blasted proir to lead plating,it is 12" dia. with a wall thickness of .115 and a bronze alloy about 88% copper.Once the plastic deformation has occured from the surface compression can it be reversed? Thanks in advance for any imput
