Setting ring 187.5 mm (DIN 2250) — Hardened, lapped gauge steel by Metav IndustryLine

The Setting ring 187.5 mm is a precision ring gauge for diametral verification and setting tasks in quality control, toolrooms and production inspection.

• DIN 2250 / DIN 286, tolerance JS3
• Hardened and lapped gauge steel
• Diameter 187.5 mm for precise setting
• Form C design for standardised checks

Consistent tolerances for reproducible measurement setup

Manufactured to DIN 2250 and DIN 286 with tolerance class JS 3, this ring offers a defined reference diameter that reduces setup variability when calibrating gauges or aligning fixtures. The standardised tolerance ensures that the ring functions as a reliable master for comparative checks and setting operations on production machinery. By providing a stable reference, process uptime and first‑pass yield are supported through quicker, more predictable setup routines.

Wear resistance and stable handling on the workshop floor

Produced from gauge steel, hardened and lapped, the ring resists abrasion and preserves its metrological surface under repeated contact. The lapped finish minimises surface roughness and promotes repeatable seating of mating parts, while the mass of 7.55 kg contributes to a vibration‑damping effect during bench use. The Form C geometry simplifies clamping and standardised placement, which helps maintain measurement integrity across shifts and operators.

Practical integration into inspection workflows

Supplied as a durable, shop‑ready reference, the ring gauge streamlines gauge setting and Go/No‑Go checks in small and medium series production. Traceability is supported by clear identification (SKU M313.187.5) and industry classification for inventory management. The compact, single‑diameter design suits bench clamping and fixture use while saving time compared with iterative measurement methods, facilitating faster control loops and consistent quality documentation.

FAQ

What is the primary use of this setting ring?
The setting ring is intended as a reference diameter for gauge setting, comparative checks and fixture alignment; the ring identified as M313.187.5 fulfils this role in inspection and workshop environments.

How does the tolerance class JS 3 affect its application?
Tolerance class JS 3 indicates a tightly controlled tolerance band under DIN 2250, making the ring suitable where repeatable, standardised settings and classification against production limits are required.

Is the surface treatment suitable for frequent use?
Yes. The ring’s hardened and lapped finish provides a wear‑resistant, low‑friction contact surface that maintains dimensional stability under repeated seating and inspection cycles.

Can this ring be used in a production line for quick Go/No‑Go checks?
The ring’s single, precise diameter and Form C design make it well suited to quick verification and Go/No‑Go procedures on the bench or in simple fixture arrangements.

Does the product come with identification for inventory and traceability?
The ring is supplied with clear identification (SKU M313.187.5) and GTIN for inventory control and traceability within quality systems.
