Gauge ball pair M318.426 — Precision gauge balls, 16 mm, hardened chrome steel (Metav IndustryLine)

A precision gauge ball pair for reference and inspection tasks in metrology and fixture setup, supplied as a matched set for repeatable diameter and roundness checks.

• Hardened chrome steel >HRC 62
• Diameter 16 mm for compact reference work
• Diameter tolerance 0.00008 mm
• Supplied as a calibrated-quality pair

Stable reference for accurate comparative measurements

The gauge ball pair serves as a compact, highly reproducible reference for a wide range of inspection tasks, from spindle runout checks to fixture alignment. With a stated accuracy of 0.003 mm and an ultra-fine surface finish of 0.00001, the pair provides a consistent datum that reduces measurement scatter and simplifies repeatability in routine checks. The matched nature of the set ensures both spheres behave identically in comparative setups, enabling straightforward use in comparative gauging and quick verification cycles without complex setups. The compact 16 mm diameter combines handling ease with sufficient contact area for many common probe and touch-trigger checks.

Wear‑resistant construction for long service life

Manufactured from hardened chrome steel, the balls resist abrasive wear and maintain form over many handling cycles, which preserves measurement integrity and reduces replacement frequency. The material hardness of >HRC 62 increases resistance to indentation and surface damage during contact measurements, so calibration intervals can be optimised and downtime minimised. The tight diameter tolerance of 0.00008 mm supports high-precision referencing even after extended use. The modest mass and compact dimensions make the pair convenient to position within fixtures or to use as portable reference artefacts in inspection benches.

Practical integration and trustworthiness in the workshop

The set is supplied as a matched pair with manufacturer traceability (SKU M318.426), making it straightforward to document reference artefacts in quality records. Its consistent geometry and surface quality simplify the interpretation of probe signals and reduce uncertainty in comparative checks, supporting efficient quality control workflows. Metav IndustryLine products are distributed from Emmerich with a tested selection process; this combination of product reliability and European distribution supports predictable supply and a clear chain of custody for workshop standards.
