Investment Casting ConcentricityAny two cylindrical surfaces sharing a common point or axis as their center are concentric. Any dimensional difference in the location of one center with another is the extent of the concentricity.![]() The illustration above shows out of roundness in either diameter does not affect concentricity because concentricity is determined by the centers or axis. Out of roundness is variance from a true circle. In a shaft or tube, straightness does not influence concentricity. ![]() ![]() When the length of a bar or tube is not more than 2 times its component diameters, the diameters will be concentric within .005" per 1" of separation.
