Thread Check Inc. offers a full range of plain cylindrical chrome ring gages in metric sizes designed to be used for go/no go gaging and as masters.Chrome ring gauges provide greater wear resistance. They also offer better corrision resistance. Plain cylindrical chrome ring gauges are ideal for inspecting outside diameters of manufactured parts. With go/no go gages, an inspector can quickly pass or fail parts without taking time consuming readings from a measuring instrument. Chrome plain Go ring gauges are built with a minus tolerance. No go ring gages are built with a plus tolerance. The go gage is used to verify the high limit. The no go gage is used to verify the lower limit. Fixed limit gages such as plain cylindrical gauges are made to match the maximum and minimum material condition of the part. The fixed limit gage is typically a three dimensional replica of the mating part. This system of gage tolerancing ensures that an inspector will never allow bad part to be accepted. Inspection using fixed limit go/no go plain cylindrical gages requires only basic training. The inspector only has to verify whether the gage is fitting over the outside diameter of their part.
Plain cylindrical ring gages are also used for mastering measuring instruments. Plain cylindrical ring gauges are used to set electronic bore gages, air gages, internal micrometers and length measuring instruments. Setting or master gages are
typically used to set a measuring instrument to a known value or zero position. By using the same size master ring gages, lead error on measurements can be eliminated.
Plain cylindrical gauges are used to check outside diameters of parts as well as for mastering measuring instruments. Plain ring gages are used to set electronic bore gages, air gages, internal micrometers and length measuring instruments. Plain gauges are ideal for gaging the outside diameter of parts. The go ring gage is used to verify the high limit of the part and the no go plain ring gauge is used to verify the low limit of the part.
Gauges are available in class XX thru class ZZ gagemaker tolerances. Class XXX tolerance gages are priced on request.
Roundness and taper does not exceed 50% of the gagemakers tolerance. Thread Check can supply gauges from .015" up to 28.00"
in diameter. The No Go ring gage is distinguished from the Go ring by an annular groove cut into the outside surface. Both cylindrical ring gauges are also marked with size, type and gagemaker tolerance. The outside diameter of a plain cylindrical
ring gage is knurled for easy handling and gripping. All plain cylindrical ring gauges are manufactured to ASME/ANSI B47.1 and ASME/ANSI B89.1.6. Plain ring gages up to 1.510"are manufactured without a flanged outer diameter. For cylindrical ring
gauges larger than 1.510", the gages have a flanged diameter. The gage has less material on the outside of the diameter thus making it easier to handle and use by the inspector.
Lead time to build all cylindrical ring gages varies from three to five weeks depending on the size and gagemaker class.
Premium expedite service is available on ring gages at an additional cost of 30-40%.
