A more comprehensive product lineup of steel ring gauges is now available. These are convenient for use for inner diameter measurement or as an inner diameter measuring instrument master. Gauge diameter (D): 1 mm to 100.00 mm (0.01 mm increments), Gauge tolerance: 5 patterns available from ±0.001 mm up to ±0.005 mm. *Selectable widths may vary depending on the combination. [Features]· Internal diameter measuring instrument master.· All products have been finished with a sub-zero treatment and stabilizing treatment.· Lapping finish provides good abrasion resistance. [Options]· Marking specification: D dimension - Specify the desired gauge diameter (D dimension) to be marked on the ring gauge.· Marking specification: tolerance - Specify the desired gauge tolerance (+/-, in 0.0001 mm increments) to be marked on the ring gauge.· Marking specification: GO / NO-GO - Specify the GO / NO-GO marking to suit your application.

A ring gauge set convenient for testing directly by passing through a spline shaft, etc.
[Features]
· A pair of ring gauges with external dimensions based on the maximum and minimum allowable dimensions as references.
· Can be used for obtaining fit compatibility between the hole and the shaft.
· Tolerance class: h7, hardness: HV 653 to 772.
· Lapping finish.
[Applications]
· Used for inspection of shaft diameter.

A ring gauge handy for measurement of round parts.

· Material: SKS3 (alloy tool steel).
· Hardness: 653 to 772 HV.
· Finished with sub zero treatment and stabilization treatment

[Features]
· It is a gauge to be used for dimensional reference in dimensional setting and inspection management of gauges and comparative measuring instruments.

Now featuring a more comprehensive lineup of carbide ring gauges with excellent durability.

Gauge diameter (D): 1 mm to 50.00 mm (0.01 mm increments)
Gauge tolerance: 5 patterns available from ±0.001 mm up to ±0.005 mm
*Selectable widths may vary depending on the combination.


[Features]
· Features outstanding wear resistance for a long service life.
· There is little impact from temperature, as thermal expansion coefficients are small.
· No need to worry about scratching of the surface due to a high degree of hardness.

[Options]
· Marking specification: D dimension
　Specify the desired gauge diameter (D dimension) to be marked on the ring gauge.
· Marking specification: tolerance
　Specify the desired gauge tolerance (+/-, in 0.0001 mm increments) to be marked on the ring gauge.
· Marking specification: GO / NO-GO
　Specify the GO / NO-GO marking to suit your application.

Go and No-Go are integrated by a protective cover for an easy-to-handle gauge with no concerns about loss.
[Features]
· A paired limit ring gauge for opening and closing is embedded in the aluminum protective cover.
· Perform measurements with bare hands, because the included protective cover will keep dirt on hands from soiling the gauge.
· Simple handling due to minimal temperature changes from body temperature.
· Tolerance class: h7.
[Applications]
· Used for inspection of shaft diameter.

Master gauges are gauges used for dimensional settings reference for comparative measuring instruments.

Now featuring a more comprehensive lineup of economical ceramic ring gauges with excellent workability.

Gauge diameter (D): 3 mm to 50.00 mm (0.01 mm increments)
Gauge tolerance: 5 patterns available from ±0.001 mm up to ±0.005 mm
*Selectable widths may vary depending on the combination.


[Features]
· Features exceptional abrasion resistance in comparison to steel and is a material that strongly resists change over time while preventing variations in dimensions.
· Maintenance after use is very easy, with no fear of rust and corrosion.
· Because it is made from a non-magnetic material there is no risk of magnetization.
· There is little change in plasticity due to scratches or dents and there are no burrs or bulking.
· Lightweight for easy measurement.

[Options]
