Ceramic gauge ball (Si3N4), 15 mm — 0.003 mm accuracy (Metav IndustryLine)

A Ceramic gauge ball (Si3N4), 15 mm, designed as a durable reference sphere for tactile probes, fixtures and precision inspection tasks in metrology and production environments

• Si3N4 ceramic for high wear resistance
• Diameter 15 mm with 0.003 mm accuracy
• Extremely low surface roughness Ra 0.00001
• Hardness HV1400–1700 ensures long life

Precision where repeatable references matter

As a hardened measurement sphere manufactured from Si3N4, the component delivers a combination of low mass, thermal stability and surface integrity that supports repeatable contact measurements. The sphere’s 0.003 mm accuracy and tight diameter tolerance reduce uncertainty when used as a reference in probe calibration or as a master artefact in inspection fixtures. The material’s high wear resistance maintains geometry over many cycles, which translates into fewer replacements and steadier long‑term measurement performance.

Reliable probing and fixture performance

The gauge ball’s 15 mm size is immediately compatible with common tactile probes and small clamping fixtures, offering a compact yet stiff reference point. A very fine surface finish and a diameter tolerance of 0.00008 mm minimise local contact deformation and signal noise during touch‑trigger or scanning routines. In practice this means more consistent probe readings and better conformity between production checks and laboratory measurements, supporting efficient in‑line quality control.

Durable construction and practical integration

Manufactured with a hardness of HV1400–1700, the sphere resists abrasive wear in demanding environments and keeps its form under repeated contact. The low inherent weight (0.08 kg) eases handling and reduces inertia effects for dynamic probing, while the robust ceramic base lowers the risk of corrosion or chemical attack compared with metallic alternatives. Clear identification via SKU and GTIN enables straightforward inventory and traceability in technical stores and metrology labs.
