Setting ring 37 mm — gauge ring for calibration, hardened and lapped (Metav IndustryLine)

The Setting ring 37 mm is a compact precision gauge ring intended as a dimensional master for calibration tasks and fit verification in inspection and production environments.

• Hardened and lapped gauge steel
• Conforms to DIN 2250 and DIN 286
• Tolerance grade JS 3 for accurate fits
• Compact 37 mm diameter reference

Precision engineered for dependable master measurements

The ring is manufactured from gauge steel, hardened and lapped, a combination that ensures high surface quality and dimensional stability. Compliance with DIN 2250 and DIN 286 guarantees defined tolerances and surface conditions; the JS 3 grade specifies the narrow tolerance band used for reference gauges, which directly reduces measurement uncertainty in go/no‑go checks and setting procedures. The design focus on repeatability supports consistent tool setting and fixture calibration over many cycles.

Robust reference for everyday inspection and setting tasks

A solid, wear‑resistant ring made from temper‑stabilised steel provides long service life under routine handling and repeated contact with setting instruments. As a metrological reference, the component minimises setup time on presetting devices and ensures reliable mating with shafts or mandrels during pass/fail checks. The combination of hardened substrate and a fine lapped finish reduces risk of fretting and surface damage, preserving the reference dimension across many measurement operations.

Time‑saving certainty in production control

Using a clearly specified reference ring shortens calibration workflows and lowers cumulative measurement drift: because the ring meets recognised standards and a fixed tolerance class, checks can be automated or standardised across shifts with predictable outcomes. The compact diameter makes the item easy to store and integrate into bench kits or gauge sets while still delivering the stability expected from master gauges. Traceable labelling and a consistent manufacturing routine further support process documentation and quality records.
