Mitutoyo 177-319 Setting Ring 3.5″ Size 0.98″ Width Calibration

Description

Product Overview

The Mitutoyo 177-319 Setting Ring is engineered for high‑precision dimensional calibration across a wide range of industrial and scientific applications. Constructed from hardened stainless steel, the ring provides exceptional durability while maintaining a stable geometry that resists wear and deformation over repeated use. The ring’s 3.5″ inside diameter and 0.98″ width are carefully machined to meet the stringent tolerance of ±0.00006″, delivering repeatable zero settings for inside micrometers, dial bore gauges, and hotends. Each ring is laser‑etched with its exact inside diameter, eliminating guesswork and reducing setup time. The compact 5.51″ outside diameter and lightweight design (4.38 lb) allow easy handling and storage, while the robust packaging dimensions of 6.42 × 6.3 × 1.26 in ensure protection during transit.

Usage

Designed for professionals who demand accuracy, this setting ring integrates seamlessly into routine calibration workflows. In a machine shop, technicians can quickly insert the ring into an inside micrometer to establish a known reference point before measuring critical bore dimensions. In research laboratories, the ring serves as a reliable standard for verifying the performance of dial bore gauges and hotends used in additive manufacturing processes. Its versatility extends to quality‑control stations where rapid zeroing reduces downtime and improves throughput. The ring’s clear markings and ergonomic shape make it suitable for use in both cleanroom environments and rugged field conditions, ensuring consistent results regardless of the operating context.

FAQ

What measurement tools are compatible with this setting ring?

The ring is compatible with inside micrometers, dial bore gauges, and hotends that accept a 3.5″ inside diameter reference. It can also be used with any calibrated instrument that requires a known zero reference for bore measurements.

How does the accuracy of ±0.00006″ compare to other setting rings?

Mitutoyo’s tolerance of ±0.00006″ is among the tightest available in the market, providing a higher level of confidence for critical dimensional inspections than typical rings that often have tolerances of ±0.0001″ or larger.

Can the ring be used in temperature‑controlled environments?

Yes, the stainless‑steel material is stable across a wide temperature range, making the ring suitable for use in temperature‑controlled labs or environments where thermal expansion could affect measurement accuracy.

What is the recommended maintenance procedure?

To maintain accuracy, keep the ring clean and free of debris. Wipe it with a lint‑free cloth after each use and store it in its original packaging to protect against scratches and contamination.

Is there a warranty or guarantee for this product?

Mitutoyo provides a limited warranty that covers manufacturing defects for a period of one year from the date of purchase. Contact Mitutoyo customer service for warranty claims or replacement inquiries.
