all cylindrical rings are manufactured to asme/ansi b47.1 agdstandard and asme/ansi b89.1.6.when min and max master rings (.005"/.125mm max spread) areordered for setting variable gages, the two price mat beused.all rings regardless of size are lapped to size andpolished.non gaging surfaces are black oxide and ring faces are surfaceground.roundness and taper to not exceed 50% of the applicablegagemaker’s size tolerance and are non-accumulative.sizes available up to 28".
the designs for cylindrical ring gages are described in asmestandard b47.1.
rings below 1.510" are manufactured without a flanged outerdiameter.
available in steel, carbide or chrome.
above 1.510" cylindrical rings are manufactured with a flangeddiameter as pictured above.
the removal of excess material from the outside diameterreduces weight for easier use by the operator.
available in steel, carbide or chrome.
jacketed carbide ring gages:
pictured above is a "jacketed carbide" ring.
the insert is solid carbide with the outside jacketed withsteel.
a solid carbide ring would be heavy and subject to damage onthe outside due to the carbide being hard and brittle.
