Setting ring M313.185 – 185 mm hardened gauge steel, DIN 2250 (Metav IndustryLine)

The Setting ring M313.185 is a precision ring gauge designed for setting, inspection and calibration tasks in toolmaking and metrology, providing a stable reference for internal-diameter checks and instrument adjustment.

• Hardened, lapped gauge steel
• DIN 2250 / DIN 286, JS 3 tolerance
• Form C contour for versatile fits
• Nominal diameter 185 mm

Consistent accuracy for fast, repeatable setups

The ring serves as a stable reference that reduces adjustment cycles and supports faster throughput on the shop floor. Manufactured from hardened gauge steel with a lapped finish, this component maintains dimensional integrity over time and resists wear that would otherwise affect fits. Conformity with DIN 2250 and DIN 286 and the JS 3 tolerance class means the ring can be used as a verified standard for comparison measurements and instrument setting, giving measurable benefits in reproducibility and process control.

Robust construction to withstand industrial use

A Form C profile and the solid construction ensure secure seating in fixtures and consistency during repeated use. The substantial mass contributes to stability during inspection and helps prevent movement that would introduce measurement scatter. The lapped surface minimises friction and contact wear, lowering maintenance needs and extending service intervals in daily operation. These attributes make the ring suitable for routine setting tasks in machining, assembly and quality-control environments.

Practical application: where the ring excels in production

Use the ring gauge as a master for setting internal measuring instruments, aligning bore gauges, checking mandrels and validating plug gauges. Its 185 mm nominal diameter and precise finish simplify pass/fail comparisons and reduce setup-related scrap by improving first-time conformity. The ring’s geometry also aids in repeatable placement in jigs and fixtures, so inspection steps become faster and less dependent on operator technique, yielding immediate productivity gains for workshops and small-series production.

FAQ

What does the JS 3 tolerance mean for a ring gauge?
The JS 3 class specifies the permissible deviation band for the nominal diameter; the Setting ring M313.185 meets this class under DIN requirements, enabling consistent repeatability for comparative measurements.

Which material and finish are used on this ring?
The ring is made of hardened gauge steel and delivered with a lapped surface to reduce wear and maintain accuracy over prolonged use.

For which tasks is this ring most suitable?
The component is intended for instrument setting, internal-diameter references, bore-gauge alignment and pass/fail checks in toolmaking and inspection workflows.

Can this ring be used in a production workshop rather than a metrology lab?
Yes; the robust construction, lapped finish and Form C profile make the unit well suited to industrial workshop environments where durability and repeatability are required.

How should the ring be handled and stored to preserve accuracy?
Handle the ring carefully to avoid impacts; store in a clean, dry environment and protect the lapped surface from abrasives and corrosive agents to preserve measurement integrity.
