Smooth ring gauge: It is a type of gauge used to measure the outer diameter dimension of the workpiece, divided into T end and Z end. In use, the T end represents the upper limit dimension of the outer diameter of the workpiece and should pass; the Z end represents the lower limit dimension of the outer diameter of the workpiece and cannot pass.

Ring Gauge Use

A ring gauge is a precision measuring tool used primarily in machining and quality control to measure the external dimensions of cylindrical objects, such as shafts or bearings. It is designed to check the size and roundness of these components, ensuring they meet specific tolerance requirements. Ring gauges are commonly used in industries such as automotive, aerospace, and manufacturing, where maintaining precise dimensions is crucial.

Ring gauges come in two main types: Go/No-Go gauges and set-ring gauges. The Go/No-Go type is used for basic tolerance checking. It consists of two rings: the "Go" ring and the "No-Go" ring. The "Go" ring should fit the part, indicating that the component is within the desired size range, while the "No-Go" ring should not fit, indicating the part exceeds the specified dimensions.

The set-ring gauge is used for more detailed measurement and calibration. This type consists of a precisely manufactured ring that serves as a standard to compare against the component being measured. It helps verify that components maintain consistent size throughout production processes.

Ring gauges are made from materials with low expansion rates, such as steel or carbide, to ensure they maintain their precision even under varying temperature conditions. When using a ring gauge, it is essential to handle it carefully to avoid damage, as even a small imperfection can affect measurement accuracy.

In summary, ring gauges are vital for ensuring high-precision measurement of cylindrical parts in various industries. Their use helps prevent defects and ensures components fit and function as intended, contributing to the overall quality and performance of mechanical systems.

What is the Advantage of Ring Gauge?

In the manufacturing and engineering industries, ensuring precise measurements is crucial for the quality and performance of components. One essential tool that plays a significant role in achieving accurate measurements is the ring gauge. This specialized measuring instrument provides numerous advantages that enhance productivity and quality assurance processes.

First and foremost, the primary advantage of a ring gauge is its ability to provide highly accurate measurements for cylindrical parts. Its design allows users to check the diameter of a workpiece effectively. Ring gauges are manufactured to stringent tolerances, making them ideal for quality control in rigorous environments. This precision helps to ensure that parts fit together seamlessly, reducing the likelihood of assembly issues.

Another prominent advantage of the ring gauge is its simplicity of use. Unlike more complex measuring tools, ring gauges present a straightforward 'go/no-go' method for inspection. The design consists of two rings – a go ring that should fit onto the part and a no-go ring that should not. This binary approach allows for quick assessments, enabling operators to identify non-conforming parts swiftly without the need for intricate measurement setups.

Moreover, ring gauges are highly durable and can withstand extensive use, leading to a long lifespan and reduced costs in the long run. They are often made from hard materials that resist wear and tear, making them suitable for repetitive daily checks in various production settings.

Lastly, implementing a ring gauge in your quality control process can significantly enhance the overall efficiency and reliability of manufacturing operations. Ensuring that every manufactured piece meets the required specifications not only elevates product quality but also fosters customer satisfaction and trust.

In conclusion, the advantages of using a ring gauge are multifaceted, encompassing accuracy, user-friendliness, durability, and efficiency. By integrating ring gauges into your manufacturing processes, you can achieve enhanced quality control and improve the overall standard of your products.

STORAEN Ring Gauge Specification: Dual Standard Certified in Accordance with GB1957/DIN7162

STORAEN’s ring gauges stand as a testament to precision engineering, meticulously designed to comply with both GB1957 and DIN7162 international standards—two benchmarks of excellence in dimensional metrology. Engineered to achieve accuracy up to h6 class, these gauges serve as master ring gages, setting the gold standard for bore diameter measurements in industries where precision is non-negotiable, from automotive manufacturing to aerospace engineering and industrial machinery production.

Crafted from premium-grade alloy steel, our steel ring gauges undergo a rigorous heat-treatment process to enhance hardness and resist wear, ensuring consistent performance even in harsh industrial environments. The material’s low thermal expansion coefficient minimizes errors caused by temperature fluctuations, a critical feature for maintaining reliability in global manufacturing settings. Each gauge features a polished surface finish, reducing friction during measurements and protecting against accidental scratches that could compromise accuracy.

Our product range includes both plain ring gages for single-dimension inspections and ring gauge sets that bundle multiple sizes, ideal for workshops requiring versatile quality control solutions. Whether you need a gauge for verifying the inner diameter of a precision-machined bearing or calibrating the bore of a hydraulic component, STORAEN offers configurations that align with your specific needs. All gauges adhere to the Go/No-Go measurement principle: the "Go" end confirms a part’s dimensional conformity, while the "No-Go" end ensures it does not exceed allowable tolerances, streamlining inspection processes for efficiency.

The ring gauge class h6 designation signifies our commitment to ultra-tight tolerances—typically within ±0.0005mm for nominal sizes up to 50mm—making our gauges suitable for applications demanding micron-level precision. This level of accuracy is validated through our in-house calibration laboratories, equipped with advanced interferometers and coordinate measuring machines (CMMs), ensuring each gauge meets or exceeds the strictest international tolerance standards. Every product is accompanied by a traceable calibration certificate, linking its performance to national metrology standards for full compliance documentation.
