Setting ring 275 mm — hardened & lapped gauge steel (Metav IndustryLine)

The Setting ring 275 mm is a precision master ring for setting, go/no‑go checking and calibration tasks in metrology and workshop inspection.

• Hardened, lapped gauge steel
• Diameter 275 mm
• Form C geometry
• DIN 2250 / DIN 286 JS4 compliant

Stability that shortens setup time

A stable reference reduces repeat measurements and set‑up adjustments. The heavy, machined body of this master ring provides a consistent datum across repeated cycles: the 275 mm internal diameter is produced in hardened, lapped gauge steel, which limits wear and preserves the reference form. For machine shops and inspection benches this means fewer rechecks, quicker fixture alignment and a measurable reduction in process downtime. The solid construction (approx. 11.15 kg) also dampens handling variation, improving reproducibility during manual checks.

Precision produced to recognised standards

Traceable geometry is essential for trustworthy checks. The component is manufactured to DIN 2250 and DIN 286, JS4 tolerances, ensuring the ring meets established industry limits for roundness and dimension. Compliance with these norms means the part can serve as a master for setting instruments and verifying measuring equipment against an accepted standard. The lapped finish delivers a fine surface that supports accurate contact measurement without introducing local deformation.

Practical design for workshop use

Form C geometry keeps the ring accessible for gauges and setting fixtures while maintaining rigidity where it matters. The hardened and lapped material resists abrasion from frequent use, so the ring remains a dependable reference over long service intervals. Its mass and profile are balanced to allow safe handling by one or two technicians and to sit stably on plates or in soft jaws during verification tasks. Where repeatability and durability are priorities, this configuration offers a sound compromise between portability and long‑term stability.

What this delivers to quality management

Using a certified, robust master ring simplifies audit preparation and daily quality routines: fewer measurement deviations, clearer pass/fail decisions and a reduced need for corrective rework. The ring functions as a direct setting aid for workholding, a go/no‑go master for assembly control and a calibration artefact for shop‑floor gauges. Choosing a Metav IndustryLine master ensures the reference part is supported by a supplier experienced in scaling industrial metrology to everyday workshop needs.

FAQ

What is the primary use of this setting ring?
The setting ring 275 mm serves as a master reference for setting fixtures, performing go/no‑go checks and verifying measuring instruments in workshop and inspection environments.

Which standards does the ring conform to and what does that mean?
The ring conforms to DIN 2250 and DIN 286, JS4, which define dimensional and tolerance requirements for ring gauges; this ensures the ring can be used as a traceable workshop reference.

Is the material suitable for frequent contact measurements?
Yes — the hardened and lapped gauge steel construction is designed to resist wear from repeated contact, maintaining dimensional stability over prolonged use.

How should the ring be handled and stored to preserve accuracy?
Handle the ring on stable, clean surfaces and avoid impacts; when not in use, store in a dry, dust‑free area on a padded support to protect the lapped surface and preserve the reference form.
