Caliper Standard Ring Gauge INSIZE PIERSCIEN WZORCOWY FI 50, Ø50 mm, MPN 6312-50

INSIZE PIERSCIEN WZORCOWY FI 50 is a precision ring gauge with a nominal diameter of 50 mm designed for accurate go/no-go checking and calibration of internal bore measuring instruments. It offers a fixed reference diameter that helps maintain measurement consistency in workshop, inspection, and metrology environments. The ring gauge is produced to provide a stable, repeatable checking standard for bore gauges, internal micrometers and other internal measuring tools.

Advantages

The ring gauge delivers a stable reference diameter that supports rapid verification and setup of internal measurement tools. Its hardened and ground bore resists wear and preserves accuracy over repeated use. The compact, simple design requires no power and is easy to handle, enabling quick compatibility checks and on-the-spot inspection without complex fixturing.

Suitable for

• Go/no-go checking of internal bore gauges and plug gauges
• Calibration and verification of internal micrometers and telescoping gauges
• Workshop quality control and production line spot checks
• Assembly and inspection stations where a fixed reference diameter is required

Key specifications

• Nominal diameter: 50 mm
• Type: ring gauge (caliper standard) for internal measurement verification
• Material and treatment: hardened and ground bore for wear resistance (material specifics per manufacturer)
• Accuracy: manufactured to metrology-grade tolerances suitable for inspection and setup tasks
• Form: circular ring with a fixed internal diameter for go/no-go checking

How to use

Clean both the ring gauge and the measuring instrument before use to remove debris and ensure contact integrity. Insert the internal measuring tool into the bore and check for go/no-go fit or compare instrument readings against the fixed diameter. Use gentle, consistent pressure and support the gauge on a stable surface to avoid deflection. Record results and, if needed, adjust the measuring instrument per its calibration procedure.

Usage recommendations

Store the ring gauge in a clean, dry environment and protect it from impacts. Periodically inspect the bore for wear or damage and recalibrate or replace the gauge if measurement drift is detected. Avoid exposing the gauge to corrosive substances or extreme temperatures to preserve accuracy.
