Mitutoyo Setting Ring 0.65″ Size 0.39″ Width +/-0.00004″ Accuracy

Description

Product Overview

The Mitutoyo 177-182 setting ring is engineered for high‑precision dimensional calibration, offering a 0.65 inch (16.51 mm) inner diameter with a tolerance of plus‑minus 0.00004 inch (±1 µm). Crafted from hardened stainless steel, the ring provides exceptional wear resistance and maintains its calibrated dimensions even under frequent use. The outer diameter measures 1.77 inches, and the width of 0.39 inches ensures a stable fit within a variety of inside micrometers, hot‑sleeve tools, and dial bore gauges. Each ring is clearly marked with its exact inner diameter, eliminating guesswork and speeding up the zero‑setting process. The compact package dimensions of 6.26 × 4.06 × 0.59 inches and lightweight design (4.66 oz) make storage and handling effortless, while the robust construction guarantees longevity in industrial and scientific environments.

Usage

Designed for professionals who demand accuracy, this setting ring integrates seamlessly into routine calibration workflows. It is commonly employed by machinists, quality control engineers, and metrology technicians who need to quickly zero inside micrometers before measuring critical components such as engine cylinders, bearing housings, and precision shafts. The ring also serves as a reliable reference for dial bore gauges used in aerospace and automotive manufacturing, where tight tolerances are mandatory. In hot‑sleeve applications, the ring provides a stable reference surface that tolerates temperature fluctuations without compromising dimensional stability. Whether you are performing routine shop‑floor inspections or conducting laboratory‑grade calibration, the Mitutoyo setting ring delivers consistent results, reducing setup time and minimizing measurement error.

FAQ

What size range does the 177-182 setting ring cover?

The 177-182 model provides a 0.65 inch (16.51 mm) inner diameter, suitable for most standard inside micrometer and bore gauge applications that require a medium‑size reference.

Can this ring be used with hot‑sleeve tools?

Yes, the ring’s hardened steel composition and stable dimensions make it an excellent reference surface for hot‑sleeve tools, even when temperature variations occur during measurement.

How often should the setting ring be recalibrated?

Because the ring is manufactured to a tight tolerance, recalibration is typically only needed after a major impact or after extended use in harsh environments. Routine visual inspection is recommended before each use.

Is the ring compatible with all Mitutoyo micrometers?

The ring is designed to fit the majority of Mitutoyo inside micrometers and dial bore gauges. For specialized models, consult the product manual or contact our support team for confirmation.

What warranty does Mitutoyo provide for this product?

Mitutoyo offers a one‑year limited warranty covering manufacturing defects. Additional support and service options are available through authorized distributors.
