Ceramic measuring ball (Si3N4) — 10 mm, 0.003 mm accuracy by Metav IndustryLine

A ceramic measuring ball (Si3N4) designed as a precision reference sphere for gauging, calibration jigs and high‑accuracy inspection fixtures across workshop and laboratory environments

• 10 mm diameter, tight dimensional tolerance
• High hardness HV1400–1700 for wear resistance
• Diameter accuracy 0.003 mm for repeatable gauging
• Extremely low surface roughness Ra 0.00001 for stable contact

Consistent material properties for durable references

Made from Si3N4 ceramic, the sphere combines mechanical hardness and dimensional stability that matter in repetitive measurement tasks. The hardness HV1400–1700 increases resistance to surface abrasion, which helps maintain contact geometry over many cycles. For gauging systems and fixture pins this translates into fewer replacement intervals and more predictable measurement drift, supporting efficient maintenance planning and reduced downtime.

Measurable accuracy that improves repeatability

With a stated accuracy of 0.003 mm and a diameter tolerance of 0.00008 mm, this precision sphere provides a reliable datum for comparative and absolute checks. The exceptionally low surface roughness (Ra 0.00001) reduces micro‑slip at contact points, improving repeatability in probe‑based or mechanical gauging. In practical terms, using such a reference sphere makes it easier to trace measurement uncertainty and maintain consistent quality control in serial inspection.

Easy integration and stable handling in metrology setups

At 10 mm diameter and a mass of 0.08 kg, the reference sphere is compact yet substantial enough for secure fixturing in test rigs and assembly jigs. The material choice supports stable thermal behaviour in typical workshop conditions, so dimensional changes remain minimal during short handling periods. Where fixture geometry demands consistent contact conditions, this precision sphere serves as a dependable mechanical reference that simplifies calibration tasks and fixture verification.

FAQ

What is the intended use for this ceramic measuring ball?
The ceramic measuring ball is intended as a precision reference for gauging, calibration jigs and inspection fixtures where a stable contact point at 10 mm diameter is required.

How does the 0.003 mm accuracy affect measurement results?
An accuracy of 0.003 mm reduces one source of uncertainty when the sphere is used as a datum, improving repeatability in comparative checks and probe calibrations with the Metav IndustryLine reference sphere.

Is the surface finish important for probe measurements?
Yes. The very low Ra 0.00001 surface roughness minimises micro‑movement at the contact interface, which helps probes and mechanical gauges deliver more consistent readings.

Can the sphere be used in high‑volume fixture environments?
The high hardness (HV1400–1700) and ceramic construction make the sphere suitable for repetitive contact in fixtures; long‑term wear is significantly reduced compared with softer materials.

Which systems is the sphere compatible with?
The sphere functions as a mechanical reference in manual and automated gauging systems, probe calibration setups and fixture verification processes; its compact size aids integration into standard metrology tooling.
