Metav IndustryLine Setting Ring 120 mm — hardened, lapped gauge steel (Form C)

The Setting ring 120 mm is a precision reference gauge for setting and checking internal and external measuring devices in workshop, inspection and production environments.

• DIN 2250 / DIN 286, tolerance JS 3
• Hardened, lapped gauge steel
• 120 mm diameter
• Form C design

Reproducible setups that reduce machine downtime

The setting ring serves as a compact reference gauge that shortens setup time during tool changes and inspection routines. Manufactured from hardened and lapped gauge steel, the component offers a stable contact surface and low wear rate, which contributes to consistent repeatability. Conformity with DIN 2250 and DIN 286 at JS 3 tolerance makes the ring suitable as a shop-floor master for routine checks and for establishing traceable reference points in assembly and metrology tasks.

Practical applications in production and inspection

Designed for use as a setting and control standard, the component is ideal for calibration of collets, internal micrometers and comparative gauges where a 120 mm reference is required. The Form C design simplifies handling and seating on fixtures while maintaining a defined measuring face. As a workshop standard, this reference gauge helps to avoid rework by enabling faster verification of holding fixtures and spindles, thereby supporting higher first-pass yields and predictable throughput.

Robust construction for long service life and easy handling

The combination of hardened substrate and precision lapped finish ensures minimal surface deformation and excellent contact quality under repeated use. The ring’s geometry and finish reduce the influence of minor contaminants and provide reliable seating during comparative measurements. For maintenance, a simple cleaning routine and storage in a dry, protected environment preserves the calibration state and surface integrity, extending the service interval between checks.
