Setting ring 137.5 mm (DIN 2250) — hardened gauge steel, Form C — Metav IndustryLine

The Setting ring 137.5 mm is a hardened, lapped ring gauge for precise setting and verification of mandrels, fixtures and reference diameters in inspection and workshop environments.

• Hardened & lapped gauge steel
• Conforms to DIN 2250 and DIN 286
• Form C geometry for stable seating
• High mass for enhanced dimensional stability

Repeatable measurement and conformity for production control

The ring gauge is manufactured to DIN 2250 and DIN 286 standards with a JS 3 tolerance class, enabling reliable repeatability in setting procedures and go/no‑go checks. The tight tolerance class provides a measurable baseline for process control and statistical inspection routines, reducing uncertainty during first‑article checks or routine machine setups. As a hardened reference component, the ring supports consistent calibration chains and traceable comparators in a quality system.

Robust construction for long service life and minimal wear

Made from hardened, lapped gauge steel, the component delivers superior wear resistance and stable seating during repeated use. The lapped finish ensures low surface roughness and precise contact geometry, which preserves the gauge’s nominal diameter over long duty cycles. The Form C profile improves support and centring on mandrels or spigots, and the unit’s mass contributes to thermal and mechanical stability during measurement operations, lowering the risk of transient errors.

Practical use cases: inspection, setup and fixture verification

Designed as a workshop and metrology tool, this ring gauge is suited to setting fixtures, verifying spindle runout with reference plugs and checking internal diameters against a calibrated standard. In production environments it shortens setup time by offering a ready reference that integrates into workflow sequences for machine alignment or tool presetting. The robust finish and standards conformity make the component apt for both shop‑floor use and controlled inspection rooms where reproducibility is required.
