Ceramic measuring ball (Si3N4), 6 mm, 0.003 mm accuracy — Metav IndustryLine reference sphere

Ceramic measuring ball (Si3N4), 6 mm, 0.003 mm accuracy is a compact reference sphere designed for high-precision gauging, calibration rigs and laboratory standards in industrial measurement setups

• Si3N4 ceramic, exceptionally hard
• 6 mm diameter with 0.003 mm accuracy
• Diameter tolerance 0.00008 mm
• Surface roughness Ra 0.00001

Fewer rejects through measurable, repeatable precision

The compact 6 mm sphere serves as a stable reference sphere where repeatability matters. With a declared accuracy of 0.003 mm and a diameter tolerance of 0.00008 mm, the component provides a verifiable datum for comparison measurements and gauge setting. This measurable precision translates into fewer false rejects and consistent inspection results, helping to streamline quality-control routines and reduce time lost to rework.

Material properties that deliver longevity and stability

Made from Si3N4 ceramic, the sphere benefits from extreme hardness (HV1400–1700) and exceptional surface finish (0.00001 Ra), which together ensure outstanding wear resistance and minimal change in contact geometry over many cycles. The ceramic's low thermal expansion provides improved dimensional stability across temperature swings compared with many metals, so the sphere maintains its reference integrity in mixed-environment production areas. The combination of hardness and fine roughness also reduces contact wear on mating gauges.

Practical integration into inspection workflows

As a compact reference element, the sphere fits into air gauging jigs, tactile probes and comparator fixtures where a reliable master is required. The low surface roughness aids repeatable probe contact and reduces measurement scatter; the tight tolerance aids in traceable set-ups. Supplied as a single, ready-to-use component, it can be used as a calibration artefact in short-run metrology tasks or as a regular reference check in serial inspection, supporting efficient throughput without compromising measurement confidence.
