Cylindrical Ring Gages

Osborn Products, Inc.offers a full range of plain cylindrical ring gages for Go/No Go gaging and as masters. Plain ring gages are ideal for inspecting outside diameters of manufactured parts. With Go/No Go ring gages, an inspector can quickly pass/fail parts without taking time consuming readings from a measuring instrument. Thread ring gages are also ideal for use as masters for setting bore gages, air gages, and internal micrometers. By using the same size master ring gages, lead error on measurements can be eliminated. Ring gages are available in class XX thru class ZZ gagemaker tolerances. Cylindrical ring gages are available in quality tool steel, chrome, carbide and ceramic materials. Feel free to contact our friendly and knowledgeable staff for any questions or assistance regarding our selection of cylindrical ring gages.
