Gauge ball pair M318.416 — 6 mm precision reference spheres by Metav IndustryLine, hardened chrome steel

A gauge ball pair (6 mm) designed as a stable, high‑precision reference for gauging, fixture alignment and comparison measurements in metrology applications.

• 6 mm diameter hardened chrome steel
• Precision 0.003 mm for reference use
• Diameter tolerance 0.00008 mm
• Supplied as a set of two spheres

Reference accuracy for reliable measurement chains

These precision spheres act as compact, repeatable reference artefacts where dimensional certainty matters. With an indicated accuracy of 0.003 mm and a diameter tolerance of 0.00008 mm, the pair supports traceable checks of probes, fixtures and comparison gauges. The very low surface roughness (0.00001) reduces contact uncertainty during probe or tactile checks, which improves reproducibility in inspection routines and reduces the need for repeated adjustments.

Engineered hardness and material stability for long service life

Manufactured from hardened chrome steel with a hardness rating above HRC 62, the spheres resist wear under repeated contact and maintain form stability across numerous measurement cycles. This material choice ensures that dimensional drift is minimised and that reference characteristics remain stable, supporting long‑term quality assurance workflows in workshop and laboratory environments.

Practical integration into inspection and fixture setups

Delivered as a set of two spheres, the product suits paired applications such as comparative gauging, alignment between mating parts and calibration of tactile probes. The compact 6 mm diameter balances minimal contact area with handling convenience, making the pair suitable for tight fixture geometries and precision checking where larger artefacts would be impractical.

Benefits for procurement and production control

Selecting these gauge balls provides a straightforward, cost‑effective way to raise measurement confidence across production steps. The robust material and tight tolerances reduce corrective downtime, while the small size simplifies storage and in‑process checks. For buyers seeking dependable reference artefacts from a reputable supplier, this set offers a consistent basis for routine verification and quality control documentation.
