Mitutoyo Setting Ring 177-180 .500″ ID Hardened Steel Calibration Ring

Description

Product Overview

The Mitutoyo 177-180 setting ring is a precision‑engineered component designed for dimensional calibration tasks across a wide range of industrial and scientific applications. Constructed from hardened alloy steel, the ring offers exceptional wear resistance and dimensional stability, ensuring that the .500 inch internal diameter remains accurate even after repeated use in demanding environments. The ring’s surface is finished to a fine tolerance, providing a smooth, repeatable contact surface that minimizes measurement error when used with bore gages, holtests, and inside micrometers. Its compact dimensions—measuring just 3.86 x 2.2 x 1.3 inches—make it easy to store in toolboxes, calibration kits, or on‑site workstations, while the clear, laser‑etched ID marking eliminates guesswork and speeds up setup time. The product carries Mitutoyo’s reputation for quality, backed by a history of over a decade of reliable performance since its first release in November 2009.

Usage

In practical terms, the setting ring serves as a reference standard for zeroing a variety of internal measurement tools. When a technician inserts a bore gage or holtest into the ring, the tool’s internal jaws or probes rest against the precisely machined inner surface, allowing the user to adjust the instrument to a known baseline. This process is essential for maintaining the accuracy of subsequent measurements on workpieces such as engine cylinders, hydraulic components, and precision‑machined parts. The ring’s robust construction also makes it suitable for field calibration where temperature fluctuations and mechanical shocks are common. Whether used in a high‑tech manufacturing floor, a research laboratory, or an on‑site maintenance crew, the Mitutoyo setting ring provides a dependable reference that reduces downtime and improves overall quality control.

FAQ

What is the purpose of a setting ring?

A setting ring provides a known reference dimension that allows users to zero or calibrate internal measurement tools, ensuring that subsequent measurements are accurate and repeatable.

Can the ring be used with digital micrometers?

Yes, the ring’s precise internal diameter works with both analog and digital inside micrometers, making it a versatile tool for a range of measurement equipment.

How does the hardened steel affect performance?

The hardened steel resists deformation and wear, which means the ring retains its exact dimensions over many calibration cycles, reducing the need for frequent replacement.

Is the ring suitable for high‑temperature environments?

While the ring is designed for general industrial use, extreme temperature conditions may affect its material properties. For high‑temperature applications, consult Mitutoyo’s technical support for a suitable alternative.

What size is the ring and how does it fit in standard toolboxes?

The ring measures approximately 3.86 inches in length, 2.2 inches in height, and 1.3 inches in width, allowing it to be stored comfortably in most standard toolboxes and calibration kits.
