Setting ring 325 mm — hardened gauge-steel ring gauge (Form C) by Metav IndustryLine

Setting ring 325 mm is a precision ring gauge intended as a stable master for workshop and production inspection, offering a robust reference for fixture setting and go/no-go verification in mechanical engineering.

• Hardened and lapped gauge steel
• Conforms to DIN 2250 / DIN 286 JS4
• Form C geometry for secure seating
• 325 mm diameter for medium-format components

Repeatable reference for process control and inspection

The Setting ring 325 mm is manufactured from hardened and lapped gauge steel, providing a wear-resistant surface that maintains dimensional stability under frequent use. Conformity to DIN 2250 and DIN 286 JS4 ensures the ring functions as a certified reference within defined tolerance bands, which supports traceable in‑process checks and stable quality control routines. Using a standardised reference reduces rework and increases process confidence.

Robust construction for handling and fixturing

With a nominal diameter of 325 mm and a mass of 28.8 kg, this ring offers the stiffness required for secure seating and reliable measurement transfer during fixture set-up. The Form C geometry provides consistent contact conditions for mating components, improving repeatability when used as a datum in jigs or test benches. Its solid construction minimises deformation under handling, making it suitable for regular workshop use where repeatable alignment is essential.

Practical integration into inspection workflows

Designed as a workplace master, the ring gauge supports quick go/no-go checks and reference verifications without complex procedures. The lapped finish simplifies tactile assessment and prolongs service life, while the adherence to recognised standards helps in documenting conformity during audits. For operators seeking dependable reference artefacts, this gauge streamlines routine checks and contributes to a resilient measurement chain in production environments.

FAQ

What is the intended use of this ring gauge?
The setting ring is intended as a stable workshop reference for fixture setting, go/no-go verification and routine dimensional checks in mechanical engineering; the Metav IndustryLine ring gauge M313.325 is optimised for medium-format components.

Which standards does the gauge comply with?
The gauge conforms to DIN 2250 and DIN 286, JS4, providing defined tolerance classes suitable for production inspection and documentation.

How durable is the surface finish under frequent use?
The hardened and lapped surface is designed for wear resistance and long service life; regular visual inspection and proper handling will preserve measurement reliability.

Is this ring suitable for use as a datum in jigs and fixtures?
Yes — the Form C geometry and robust construction of the setting ring make it well suited as a datum for fixturing and repeatable seating in test benches.

What handling should be observed given the weight?
At approximately 28.8 kg, safe handling procedures should be used; secure transport and stable placement during measurement are recommended to avoid impact and preserve accuracy.
