Cylindrical Plain Ring Gages

Cylindrical plain ring gages 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 ring gages are ideal for gauging 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 gage is used to verify the low limit of the part. Cylindrical plain ring gages are offered in various materials including tool steel, chrome steel, carbide, and ceramic.

Gagemaker tolerances for cylindrical gaging products range from extremely tight class XXX to more economical class ZZ. 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 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 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. Cylindrical plain gages manufactured in carbide use a solid carbide ring gauge jacketed with a steel outside sleeve. The jacketed steel sleeve reduces the weight and protects the carbide insert which is hard and brittle.

Thread Check’s expert sales engineers can assist you in selecting cylindrical ring gauges for your applications.

Progressive Cylindrical Plug Gages

Progressive cylindrical plug gages may be your best choice for checking the internal diameter of parts quickly. This gage design is ideal for high frequency and high volume inspection. Both Go and No Go diameters are combined on a single gage member, so parts can be inspected quickly in one easy operation. The progressive gage should smoothly enter the part and then stop at the high limit. Gage members are securely attached to either a taperlock handle or trilock handle with mounting bolts. Progressive cylindrical plug gages are available from .105" up to 8.0" in diameter. They can be supplied in steel, chrome or carbide materials. Plug gages tolerances range from class xx to zz. Specials and extra length gages are priced on request. Thread Check's expert sales engineers' can assist you with selecting the right gage for your application.

Gage Certification

Thread Check Inc offers 3 different levels of certification for all gages

1.       Certificate of Compliance (  C of C )

Is a general statement that the gages have been manufactured and are in conformance to the applicable gage specification. The Certificate of Compliance states that the gages have been manufactured and inspected by highly trained personnel and found to comply with the dimensions and tolerances specified. The Certificate of Compliance states that the primary reference standards for the gage calibration are traceable to System International (S.I.) units through the N.I.S. T - National Institute of Standards and Technology. The N.I.S.T. number referenced on this cert is being phased out by the requirements of A2LA. The Certificate of Compliance also states that the gages are inspected in compliance with MIL-STD 45662A, ISO 10012-1, and ANSI/NCSL Z540-1.

The Certificate of Conformance supplied by Thread Check Inc. conforms to the standard scope adopted by the American Measuring Tool Manufacturers Association – AMTMA. It is neither a contract nor a contractual representation.  The Certificate of Conformance states that the company’s responsibilities shall in no event nor for any cause what so ever, exceed the purchase price of the pertinent gage(s).

 

  • NO DIMENSIONAL SIZES OR TOLERANCES ARE LISTED ON THIS DOCUMENT
  • NO COMPANY INFORMATION OR GAGE PRESCRIBED SIZE IS LISTED ON THIS DOCUMENT
  • THREAD CHECK INC. PROVIDES THE CERTIFICATE OF COMPLIANCE FREE OF CHARGE.

 

2.       MANUFACTURER’S LONG FORM CALIBRATION (LFC)

Thread Check Inc. offers a manufacturing Long Form Calibration which provides all the critical gage dimensions and tolerances for the applicable standard. The Manufacturer’s Long Form Calibration demonstrates that the gages have been manufactured and inspected by highly trained personnel and found to comply with the dimensions and tolerances specified in the applicable standard. Long Form Calibration reports for thread gages list Pitch diameters, major diameters, minor diameters, lead, and angles. Long Form Calibration for Plain gages typically list measurements in 3 places. Thread Check does not provide calibration stickers on new gages.

Thread Check Inc. does not issue calibration frequencies on new gages.

Thread Check Inc. does not issue IDs or serial numbers unless specified by the customer.

Thread Check Inc. can supply a serial number at no additional charge if requested by the customer.

 

  • THERE IS AN ADDITIONAL COST FOR THIS RECORD.
  • THERE IS AN ADDITIONAL LEAD TIME INCURRED FOR PURCHASING THIS RECORD.
  • LONG FORM CALIBRATION MUST BE ORDERED WITH THE GAGES OR PRIOR TO THE GAGES BEING SHIPPED.

 

 

3.       ISO 17025 ACCREDITED CALIBRATION (ISO 17025 LFC)

Thread Check Inc. sends the gages to a third party calibration lab that is ISO 17025 accredited. The lab is ACLASS accredited. All critical dimensions are listed on the calibration cert. The laboratory is accredited in accordance with the recognized International Standard ISO/IEC 17025:2005. This accreditation demonstrates technical competence for a defined scope and the operation of a laboratory quality management system (refer to joint ISO-ILAC-IAF Communiqué dated January 2009).

Gage Makers’ Tolerances

Gage Makers tolerances have been established by the American Gage Design Commitee and are referenced for building and calibrating all solid ring gages, plug gages, and fixed snap gages. Gage Maker tolerances are refered to as classes. For example Class ZZ tolerance is an open tolerance or economical tolerance. There are 6 classes of tolerance - class XXX, XX, X, Y, Z, and ZZ.

See the link below for Gage Maker tolerances in inch and metric

Measuring Plain External Diameters – American vs European

A case related to pin gages being rejected by our European Customer

The ASME B89.1.5-1998 is the correct document to review. Reference para. 6.1, pg. 5 & 6 as well as Table 4 on pg. 7. The values were computed using the equation in Puttock and Thwaite’s CSIRO Technical Paper #25. This statement is also on page 6. The question that should be asked is, what is their measurement uncertainty? Remember that the Europeans add measurement uncertainty into their measurements. We do not do that in the US. Depending on the uncertainty budget, they may not have the accuracy to measure a .000020” gage. Our measurement uncertainty is .000012” based on our latest accredited calculations . This is not good enough to accurately measure a Class XX pin. Our customers accept our measurements as long as our uncertainty is stated on the calibration certificates. According to ANSI/NCSL Z540 & ISO 17025 the total uncertainty of the measurement should not exceed 4:1. That would require a total measurement uncertainty of .000005”. The only lab that I know of that can measure this accurately w/in the 4:1 Rule, and prove it, is NIST.

See the link to the NIST web site that has a calculator to assist in the measuring force calculation.

Note: The measuring force changes with the diameter of the part being inspected.
