Ceramic Measuring Ball (Si3N4), 10 mm — 0.003 mm accuracy | Metav IndustryLine

The Ceramic Measuring Ball (Si3N4) is a precision gauge sphere intended for dimensional checking, calibration and fixture validation where repeatable contact geometry is required.

• Si3N4 ceramic for high wear resistance
• 10 mm diameter with 0.003 mm accuracy
• Hardness HV1400–1700 for long service life
• Surface roughness 0.00001 mm for precise contact

Repeatable precision that speeds inspection cycles

The sphere delivers a guaranteed 0.003 mm (3 µm) accuracy, which represents a measurable improvement in repeatability for short‑range checking tasks. Such accuracy reduces scatter when comparing mating gauge faces or contact‑type sensors, so inspection loops close faster and rework is cut. Thanks to the tight diameter tolerance of 0.00008 mm, contact points remain consistent between setups, enabling efficient statistical process control and fewer calibration iterations.

Durable ceramic construction that lowers lifecycle costs

Manufactured from Si3N4 ceramic, the gauge ball combines high hardness and low wear to extend service life under repeated contact conditions. The specified hardness HV1400–1700 and the very fine surface roughness of 0.00001 mm (≈10 nm) minimise material transfer and abrasion on mating parts; this keeps measurement surfaces stable and reduces the need for part replacement. For applications where non‑magnetic behaviour and chemical stability matter, the ceramic body maintains performance where steel spheres might suffer corrosion or magnetic interference.

Compact format for versatile use and simple handling

With a 10 mm diameter and a listed mass of 0.08 kg, the sphere suits compact fixtures, plug gauges and precision jigs where a small contact radius is required. The geometry supports consistent single‑point contact for comparative gauges and tactile probes, while the fine surface finish preserves probe tips and reduces wear. The ball form is particularly useful in modular gauging systems and can serve as a reference element in bench‑level inspection or portable test rigs.
