Setting ring 70 mm (Form C) — hardened gauge steel by Metav IndustryLine

The Setting ring 70 mm is a precision ring gauge designed as a dimensional reference for calibration, go/no-go checks and process control in inspection and workshop environments.

• Form C: Cylindrical ring gauge
• Diameter 70 mm nominal
• Hardened and lapped gauge steel
• Manufactured to DIN 2250 / JS 3

Ensure traceable, repeatable reference measurements

The ring serves as a stable reference standard for setting and verifying measuring instruments. Manufactured from hardened, lapped gauge steel, the component offers high wear resistance and a fine running surface that preserves dimensional integrity during repeated use. Compliance with DIN 2250 and the inspection class JS 3 gives a defined tolerance band for quality control, making the ring suitable as a Go/No‑Go reference or for setting comparators and master gauges in routine workflows.

Improve inspection efficiency through a compact, robust design

A compact 70 mm nominal diameter concentrates precision where it is needed and minimises handling errors during gauge transfers. The Form C geometry provides a standard cylindrical reference that is easy to seat and align, reducing setup time at the bench or measuring machine. Reduced handling and reliable seating translate into fewer measurement cycles lost to repositioning, supporting faster throughput without sacrificing dimensional control.

Designed for workshop and laboratory environments

The material choice—hardened gauge steel, lapped—combines durability with surface quality that resists micro‑abrasion. The ring’s mass and construction yield thermal stability for short‑term transfers between workshop and inspection areas; typical practice is to allow brief thermal equilibration before critical comparisons. Where a calibrated reference is required for routine checks, this ring functions as a dependable master that integrates smoothly into existing quality routines.

Compliance and practical usability for quality systems

Specified to recognised standards, the component supports documented quality processes and inspection records. The nominal 70 mm diameter and the provided tolerance class allow straightforward incorporation into calibration plans and control charts. As a standardised ring gauge, it can be used to validate micrometre fixtures, comparator set‑ups or as a reference when verifying internal gauge masters, thereby reducing uncertainty in everyday dimensional control.

FAQ

What is the primary use of this setting ring?
The setting ring is intended as a dimensional reference for calibration, go/no‑go checks and instrument setting; the Setting ring 70 mm is suitable for workshop and inspection tasks where a stable reference is required.

Is the ring suitable for routine master comparisons in a quality lab?
Yes. Manufactured to DIN 2250 / JS 3 and made from hardened, lapped gauge steel, the ring is appropriate for regular master comparisons and process control applications.

How should the ring be handled to maintain accuracy?
Handle the ring with care, avoid impacts and allow brief thermal equilibration between differing ambient temperatures; store in a clean, dry location to preserve the lapped surface.

Can the ring be used to set internal gauge fixtures?
The standard cylindrical Form C geometry makes the ring suitable for setting internal fixtures and verifying comparator set‑ups where a known external reference is required.

Which material properties support long service life?
The hardened and lapped gauge steel provides enhanced wear resistance and a stable running surface, which supports longevity under normal inspection usage.
