RING GAUGE
Ring Gauge is a device, measuring instrument used to check shaft diameter tolerance
Introduction of Ring Gauge
Ring Gauge is a measuring instrument manufactured and processed by Niigata Seiki – Japan.
Ring Gauge also has many other popular names such as: Ring gauge, ring standard,...
As a mater ring gauge for "0" adjustment of measuring instruments such as:
- Bore gauge
- Inside micrometer
- Air micrometer
In addition to standard sizes, we also supply ring gauges according to custom requirements on size and tolerance.
Other ring gauge types
Ring Gauge

- Specification are provided
Ring Gauge Set
- Ring gauge set consist of frequently- used sizes.
- Material: Alloy tool steel
- Specification are provided
Ring Gauge With Maintenance Line
- Material: Alloy tool steel
- Maintenance line on steel ring gauge allows easy checking for gauge wear-out.
- When line disappears, wear is more than 1µm
- Available for sizes: 15～50mm
- Step: 1 mm
- Specification are provided
Carbide Ring Gauge
- Material: Steel with carbide insert
- Durable and long life
- The coefficinet of thermal expansion is small (1/2 steel, 5×10-6/K), so better tolerates temperature changes
- Less like to be damaged due to high harddess
- Economical- Frequent periodic calibration not required
- Step: 0.5 mm
- Surface roughness: Within Ra0.1µm
- Squareness: 0.05 / φ100
- Parallelism: Within 0.015 mm
- Sizes available: from 1.0 to 50.0 mm
- Specification are provide
Ceramic Ring Gauge
- Made of highly-durable material.
- Less affected b thermal expansion as well as free from rust
- Material: Ceramics
- Ceramic material is less susceptible to abrasion and aged deterioration than steel
- Free from rust and corrosion
- Easy maintenance
- Non-magnetic body
- Does not deform with damage, resists scratches and forming burrs
- Lightweight and easy handling
- Size is laser marked
- Step: 0.5 mm
- Surface roughness: Within Ra0.1 µm
- Squareness: 0.05 / φ100
- Parallelism: Within 0.015 mm
- Sizes available from 3.0 mm to 50.0 mm
- Specification are provide
Ring gauge With Protective Cover
- Non-slip and easy to handle
- Helps increase productivity
- Material:
Protective cover: Anodized aluminum
Gauge: Steel / Carbide / Ceramic - A ring gauge embedded in Aluminum Protective Cover
- Covered gauge is easier to handle with dirty hands
- Less susceptible to thermal expansion when holding a gauge by hand
- Protects from chipping when dropped
- Step: 1.0 mm
- Surface roughness: Within Ra 0.1 µm
- Specification are provided
