Description
Plain Ring Gauges
What it is
A precision limit gauge used for checking the external diameter of cylindrical components, such as shafts, pins and other round components. Precision GO and NO-GO gauges designed for rapid verification of external diameters. Manufactured from suitable hardened tool steels according to application requirements, our Plain Ring Gauges provide reliable, repeatable and efficient dimensional inspection for production and quality-control applications.
How it works
Plain Ring Gauges are generally manufactured with GO and NO-GO limits.
GO side: The component should pass through the ring under its own weight or with light pressure.
NO-GO side: The component should not pass through the ring.
This provides a quick and reliable method of determining whether the external diameter of a component is within the specified tolerance.
Typical applications
- Shafts
- Pins
- Bushes
- Automotive components
- Aerospace components
- Precision-machined components
- Mass-production inspection

A ring gauge is a precision measurement tool used to check the external dimensions of cylindrical objects, such as the outer diameter of a round part or a shaft. Ring gauges are designed to ensure that the diameter of the measured object falls within specified tolerance limits.
Here are some key points about ring gauges:
Design: A ring gauge consists of a cylindrical ring with an accurately machined internal diameter. The internal diameter of the ring corresponds to a specific nominal size or a predetermined tolerance.
Measurement Process:
The object being measured, such as a shaft or a cylindrical part, is passed through the ring gauge.
If the object fits easily through the ring gauge without resistance, it indicates that the diameter of the object is within the acceptable tolerance range.
If there is resistance or if the object doesn’t fit through, it suggests that the diameter is larger than the internal diameter of the ring gauge.
Tolerance Verification: Ring gauges are used to verify that the external dimensions of the measured object meet the specified tolerances.
Material: Ring gauges are typically made from hardened and precision-ground steel to ensure durability and accuracy.
Applications: Ring gauges are widely used in manufacturing, machining, and quality control processes where precise measurements of cylindrical parts are essential.
Ring gauges come in sets, each ring corresponding to a specific diameter or tolerance range. They are crucial tools for maintaining the accuracy and quality of machined components, ensuring that they meet the required specifications.
