Ring Gauge (Go/No-Go) INSIZE PIERSCIEN WZORCOWY Ø25 mm model 6312-25

INSIZE PIERSCIEN WZORCOWY ring gauge Ø25 mm (model 6312-25) is a precision go/no-go measuring standard for quick verification of external diameters. Made for dimensional control in inspection, machining and assembly processes, this fixed-diameter ring gauge provides an immediate pass/fail check for shafts and cylindrical parts. The solid, wear-resistant construction ensures consistent reference performance for quality control labs and shop-floor use where repeatable results are required.

Advantages

The gauge offers reliable go/no-go assessment without the need for complex measurement instruments, enabling fast decision-making during production and inspection. Its hardened, ground surface resists wear and maintains dimensional stability over repeated use. The compact, easy-to-handle design simplifies storage and handling in both laboratory and workshop environments. As a fixed standard, it reduces measurement variability and supports traceable quality control routines.

Suitable for

• Pass/fail verification of external diameters on shafts and cylindrical components
• Incoming inspection and final quality control in manufacturing
• Shop-floor checks during machining and assembly operations
• Calibration reference for comparative measurements and fixture setup

Key specifications

• Nominal internal diameter: 25 mm
• Type: Go/No-Go ring gauge for external diameter inspection
• Construction: hardened and ground ring body for wear resistance
• Application environment: suitable for quality control labs and workshop use
• Function: fixed reference for pass/fail checks of cylindrical parts

How to use

Position the ring gauge over the part to be inspected and attempt to pass the component through the gauge. The part that passes the "go" condition and does not pass the "no-go" condition meets the intended nominal tolerance for the specified diameter. Handle the gauge with care to avoid impacts or contamination; ensure mating surfaces are clean and free of burrs before testing. For repeatable results, store the gauge in its protective case when not in use and avoid exposure to corrosive environments.

Usage recommendations

Use the ring gauge in a controlled environment, keep measuring surfaces clean, and periodically inspect the gauge for wear. For traceable quality programs, combine ring gauge checks with calibrated measurement instruments and follow your laboratory or shop's inspection procedures.
