Setting ring 52 mm (DIN 2250) — hardened, lapped gauge steel | Metav IndustryLine

The Setting ring 52 mm is a compact reference ring gauge for inspection and tool‑setting tasks, manufactured to DIN 2250 and DIN 286 with JS 3 tolerance for workshop and production use.

• Hardened, lapped gauge steel
• DIN 2250 & DIN 286, JS 3
• Form C contact geometry
• Compact 52 mm reference diameter

Repeatable reference for tool setting and inspection

The ring serves as a stable reference standard, enabling reproducible settings and checks for fixtures, collets and measuring instruments. Made from hardened, lapped gauge steel, the component reduces surface deformation and contact variability, which translates into fewer set‑up iterations and shorter cycle times in the workshop. Compliance with established norms ensures results that integrate smoothly into quality procedures and inspection chains.

Tolerances and what JS 3 means for quality control

Built to DIN 2250 and DIN 286 with JS 3 tolerance, the ring provides a clearly defined allowance for play and fit. This class is suitable where consistent functional clearance and interchangeability are required, for example when setting go/no‑go references or verifying clamping devices. The precise geometry of the contact faces (Form C) supports accurate contact points and reduces measurement uncertainty during repetitive operations.

Durability, finish and handling benefits

The lapped finish improves surface contact uniformity and minimises abrasion during routine use, prolonging the service life of the gauge and the tools it interacts with. The choice of hardened gauge steel gives abrasion resistance and dimensional stability under normal workshop conditions, reducing the need for frequent rework or replacement. The compact form factor makes the ring easy to store and handle while preserving the physical integrity of the reference surface.

Where this ring delivers tangible gains

This reference ring is particularly valuable in toolrooms, production lines and inspection benches where quick, reliable setting and verification are essential. Use cases include setting jaw centres, verifying bore references, and routine dimensional checks in assembly and maintenance. The combination of standard conformity, robust material and compact diameter contributes to reduced downtime and more consistent quality output across batches.
