Pair of Gauge Balls M318.453 — 23 mm hardened chrome steel, 0.003 mm accuracy (Metav IndustryLine)

A Pair of Gauge Balls M318.453 designed as precision reference spheres for calibration, inspection and dimensional control in metrology environments.

• Hardened chrome steel >HRC 62
• 23 mm matched precision spheres
• Accuracy 0.003 mm for reference use

Reliable reference accuracy for inspection benches and CMMs

The matched spheres deliver a measurable reference with an stated accuracy of 0.003 mm, enabling reproducible checks on fixtures, gauge blocks and measuring machines. The given diameter tolerance of 0.00008 mm and the finely finished surface (roughness 0.00001) reduce geometric uncertainty when used as contact points or reference artefacts. In practice, a stable reference sphere of this class improves repeatability and reduces set‑up time on coordinate measuring machines and manual comparators, because dimensional deviations can be attributed to the measured part rather than the reference item.

Long service life through hardened material and stable geometry

Constructed from hardened chrome steel, rated at >HRC 62, the spheres are engineered for wear resistance and minimal deformation under repeated contact. The matched pair arrangement maintains symmetry across comparative measurements and gauge checks; the set format (two spheres per set) supports quick substitution or mirrored checks without recalibration of the reference fixture. The solid construction and ground finish preserve the nominal 23 mm geometry over extended use, making these spheres a cost‑effective component of a recurring quality control routine.

Integration into metrology workflows and practical benefits

As compact, transportable reference artefacts, the spheres are suited to laboratory benches, fixture validation and in‑process verification. The lightweight pair (total weight 0.2 kg) is easy to handle while offering the stability required for precision tasks. Using calibrated reference spheres reduces diagnostic ambiguity during maintenance of measuring equipment and simplifies documentation for inspection procedures. For bespoke setups or automated measurement cells, the matched nature of the pair supports consistent fixturing and minimises alignment offsets between reference points.
