C YLINDRICAL R ING G AGES • All cylindrical Rings are manufactured to ASME/ANSI B47.1 AGD standard and ASME/ANSI B89.1.6. • Rings made from Tool Steel heat treated to Rc 58-62. • When Min and Max master rings (.005”/.125mm max spread) are ordered for setting variable gages, the quantity two price may 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 not to exceed 50% of the applicable gagemaker’s size tolerance and are non-accumulative. • Sizes available up to 28” JACKETED CARBIDE RING GAGES LARGE FLANGED RING GAGES

•

The designs 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.

•

Above 1.510” cylindrical rings are manu- cal ri factured with a flanged diameter as pic- tured above. The removal of excess material from the outside diameter reduces weight for eas- ier use by the operator. Available in Steel, Carbide or Chrome. ailabl

SEGMENTED GAGES

• Segmented gages are an alternative to standard Ring and Disc masters. They are used in setting swing and bore gages. Segmented gages are lighter and use less storage room than standard ring and disc masters. They are made to check one or multiple diameters. • Segmented ID and OD gages are ground square to faces within .0002". Toler- ances depending on size are +/- .0005" with either class X or XX geome- try. Measurement uncertainty is within .00006" up to 21.000". The exact size can be engraved on the gage making it easier for set up. Segmented gages are made out of Tool Steel and heat-treated to Rc 58-62. • Chrome is available upon request.
