90mm Setting Ring Form C Hardened Gauge Steel DIN 2250/DIN 286 JS3 - Metav IndustryLine

The combination of hardened and lapped gauge steel, DIN-class tolerances and a stable 90 mm diameter provides a compact, wear‑resistant reference for setting and checking measuring instruments; order the ring directly via Metav Werkzeuge or ask the Metav consultants for application advice.

Setting ring 90 mm (Form C) – hardened gauge steel, DIN 2250

The Setting ring 90 mm is a precision reference gauge designed for workshop and metrology use, suitable for fixture setting, micrometer verification and repeatable calibration tasks.

• 90 mm nominal diameter, form C
• Hardened and lapped gauge steel
• Manufactured to DIN 2250 / DIN 286, JS 3
• Stable weight 1.7 kg for secure seating

Faster, more reliable setup with a compact reference

A compact reference gauge shortens setup time and reduces process variation. The 90 mm reference blank, made from hardened gauge steel and lapped to a fine finish, delivers a consistent contact surface that resists wear during repeated use. For production environments and maintenance benches this means fewer adjustments, quicker tool changes and lower risk of scrapped parts. The mass and geometry of the ring also help maintain secure seating on fixtures, improving repeatability when comparing instruments or setting micrometers.

Consistent measurements backed by DIN tolerances

Compliance with DIN 2250 and DIN 286, combined with a JS 3 tolerance grade, ensures the component meets established metrological expectations for interchangeability and fit. Those standards define permissible deviations so that the gauge can be used confidently as a reference in calibration chains. The ring’s specification therefore supports quality control procedures and helps integrate the item into existing inspection routines without guesswork or additional adjustments.

Durable design for long service life and low maintenance

The material choice—gauge steel, hardened and lapped—balances surface hardness with dimensional stability. Hardening increases wear resistance at the contact zones; lapping produces a low‑roughness surface that minimises abrasion on mating instruments. As a result, the reference blank maintains its dimensions across many measurement cycles, reducing the need for frequent replacement and lowering long‑term operating costs. Where repeatability matters, the robust construction preserves reference accuracy under normal workshop handling.

FAQ

What is the primary use of this setting ring?
The 90 mm setting ring serves as a precision reference for setting micrometers, checking gauges and establishing fixture limits; the Metav IndustryLine setting ring M313.090 is intended for repeatable workshop and inspection tasks.

How does the material treatment benefit measurement stability?
Hardening and lapping of the gauge steel reduce surface wear and produce a stable, low‑roughness contact face; this preserves dimensional stability of the Metav IndustryLine setting ring during frequent use.

Are the tolerances suitable for shop‑floor quality control?
Yes; the ring is produced to DIN 2250 / DIN 286 with a JS 3 tolerance, which is appropriate for many workshop calibration and setting operations where traceable, consistent fits are required.

Can the ring be used to check micrometer accuracy?
Yes; the ring is designed as a reference blank for micrometer and gauge setting; its stable diameter and surface finish make it suitable for verifying instrument repeatability.

Is the manufacturer information available for documentation?
Manufacturer and supply details are provided in the technical section and with the product documentation supplied by Metav IndustryLine.
