Setting Ring Mitutoyo 177-147 70mm Size 20mm Width +/-1.5µm Accuracy

Description

Product Overview

The Mitutoyo 177-147 Setting Ring is engineered for precision calibration tasks across a range of measurement instruments. Crafted from hardened steel, the ring offers a robust 70 mm outer diameter and a 20 mm width, delivering a stable platform for zeroing inside micrometers, dial bore gauges, and hottest gauges. Its tolerance of ±1.5 µm ensures that each adjustment is repeatable and reliable, meeting the stringent demands of modern manufacturing, aerospace, and research laboratories. The ring’s surface is finished to a fine tolerance, reducing wear and providing a clear, permanent marking of the target inside diameter, which simplifies setup and reduces operator error.

Usage

Designed for versatile use, this setting ring integrates seamlessly into routine calibration workflows. Technicians can quickly insert the ring into the measurement device’s spindle, align the marked diameter, and lock the zero position without the need for additional tools. Its compact size makes it ideal for on‑site field calibrations as well as controlled laboratory environments. Whether you are verifying the accuracy of a high‑precision inside micrometer on a production line or performing a detailed inspection of a dial bore gauge in a quality‑control lab, the ring provides a consistent reference point that speeds up the process and enhances confidence in the results.
