Mitutoyo Setting Ring 177-125 Calibration 8mm Size 10mm Width

Description

Product Overview

The Mitutoyo 177-125 setting ring is engineered as a high‑precision accessory that integrates seamlessly with a range of inside micrometers, dial bore gauges and hottest gauges. Constructed from hardened stainless steel, the ring offers exceptional durability while maintaining a smooth surface finish that resists wear and corrosion even in demanding workshop environments. Its 8 mm inner diameter and 10 mm width are carefully calibrated to provide a stable reference point, enabling users to achieve zero adjustments with a repeatability that meets the stringent tolerances of modern dimensional inspection. The ring’s dimensional accuracy of plus/minus 1.5 µm ensures that every measurement taken after zeroing reflects true part geometry, reducing the need for frequent recalibration and minimizing measurement uncertainty. Designed to meet ISO 286 standards, the product dimensions of 2.2 × 2.1 × 0.7 inches and a lightweight of 2.4 oz make it easy to handle, store, and transport without compromising performance. The Mitutoyo 177‑125 is a non‑discontinued item, reflecting the brand’s commitment to long‑term support and availability for professional metrology applications.

Usage

In practical terms, the setting ring serves as a quick‑change reference for technicians who need to zero their measurement instruments before inspecting critical components such as shafts, boreholes, and internal diameters. When attached to an inside micrometer, the ring provides a known dimension that allows the user to set the micrometer’s zero point without the need for a separate calibration block. This capability is especially valuable in high‑volume production settings where downtime must be minimized. The ring also functions effectively with dial bore gauges and hottest gauges, offering a consistent reference that speeds up the setup process for quality‑control inspections, maintenance checks, and research‑and‑development activities. Its compact size permits use in confined spaces, while the robust construction ensures that the ring can withstand repeated insertion and removal without loss of accuracy. Users in aerospace, automotive, medical device manufacturing, and precision engineering sectors will find the Mitutoyo setting ring indispensable for maintaining tight tolerances and ensuring product conformity.

FAQ

What instruments are compatible with the Mitutoyo 177‑125 setting ring?

The ring is compatible with most inside micrometers, dial bore gauges and hottest gauges that accept a 8 mm reference diameter, making it a versatile tool for a wide range of dimensional inspection equipment.

How does the plus/minus 1.5 µm tolerance affect measurement accuracy?

The tight tolerance means that the ring’s dimensions deviate no more than 1.5 µm from the nominal size, allowing users to achieve repeatable zero settings and reducing overall measurement uncertainty in subsequent inspections.

Can the setting ring be used in temperature‑controlled environments?

Yes, the stainless‑steel material is stable across typical laboratory and shop‑floor temperature ranges, and the ring’s accuracy is maintained when used in environments that are kept within the recommended temperature limits for precision metrology.

Is calibration required for the setting ring itself?

The ring is manufactured to meet strict dimensional specifications, but for the highest level of confidence, users may verify its dimensions against a calibrated standard during routine quality‑control checks.

What warranty or support does Mitutoyo provide for this product?

Mitutoyo offers a standard limited warranty that covers manufacturing defects, along with access to technical support, calibration services, and replacement parts through its global dealer network.
