STORAEN Ring Gauges are professional-grade precision measuring instruments engineered for the rigorous demands of modern machining and quality control. Specially designed to verify the external diameters of cylindrical components such as shafts and bearings, our gauges ensure absolute dimensional conformity and roundness. By employing the industry-standard "Go/No-Go" principle, STORAEN provides a foolproof method for rapid inspection, eliminating measurement ambiguity and ensuring every part meets strict tolerance requirements before assembly.
Manufactured from premium-grade alloy steel and carbide with low thermal expansion coefficients, these gauges maintain micron-level stability across varying temperature conditions. Whether you are operating in the aerospace, automotive, or heavy machinery sectors, STORAEN’s ring gauges serve as the foundation of your quality assurance framework. From standard GB1957 and DIN7162 certifications to fully customized non-standard diameters, we deliver the metrological reliability required to reduce rework and elevate product performance on a global scale.

| Inspection Speed | Slow (Manual reading) | Instant (Go/No-Go) |
| Accuracy Risk | Higher (Operator error) | Minimal (Fixed standard) |
| Durability | Moderate | High (Heat-treated alloy) |
| Rework Cost | High (Due to missed defects) | Low (Early detection) |
| Compliance | Basic | Full (GB/DIN Certified) |
The "Go" ring represents the upper limit of the outer diameter and must fit over the workpiece. The "No-Go" ring represents the lower limit and must not fit. If both conditions are met, the part is within the specified tolerance.
We use premium-grade alloy steel and carbide. Alloy steel is ideal for general industrial use, while carbide offers superior wear resistance for high-volume production environments.
Yes, our ring gauges are dual-certified in accordance with GB1957 and DIN7162 standards, ensuring they are acceptable for global automotive and aerospace quality audits.
Gauges should be stored in a dry, temperature-controlled environment. We recommend applying a thin layer of anti-rust oil and using a protective case to avoid surface scratches.
Absolutely. Our engineering team specializes in creating custom ring gauges with non-standard diameters, special tolerances, and customized surface coatings like chrome plating.
The h6 class indicates an ultra-tight tolerance level, typically within ±0.0005mm for sizes up to 50mm, making it suitable for high-precision master gauging applications.
