product specificatio: all cylindrical rings are manufactured to asme/ai b47.1 agd standard and asme/ai b89.1.6. when min and max master rings (.005//.125mm max spread) are ordered for setting variable gages, the quantity two price mat be used. all rings regardless of size are lapped to size and polished. non gaging surfaces are black oxide and ring faces are surface ground. roundness and taper to not exceed 50% of the applicable gagemaker’s size tolerance and are non-accumulative. sizes available up to 28/.

small ring gages:

the desig for cylindrical ring gages are described in asme standard b47.1. rings below 1.510/ are manufactured without a flanged outer diameter. available in steel, carbide or chrome.

large flanged ring gages:

above 1.510/ cylindrical rings are manufactured with a flanged diameter as pictured above. the removal of excess material from the outside diameter reduces 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 iert is solid carbide with the outside jacketed with steel. a solid carbide ring would be heavy and subject to damage on the outside due to the carbide being hard and brittle.
