Plain Ring Gauge

The Plain Ring Gauge is a precision Go / No-Go inspection gauge used for checking external diameters of cylindrical components such as shafts, pins, and machined round parts. It ensures fast and accurate verification of size and tolerance, making it ideal for production-line inspection and quality control.

Manufactured by P.S. & SONS from high-grade alloy steel, Plain Ring Gauges are hardened, stabilized, and precision ground to achieve high dimensional accuracy, excellent wear resistance, and long operational life. The fixed ring design provides consistent and repeatable inspection results without the need for measuring instruments.

Clearly marked GO and NO GO rings allow quick pass/fail checking, improving inspection efficiency and reducing operator error in high-volume manufacturing environments.
