Measuring Ball Si3N4 30 mm — Ceramic precision sphere, 0.003 mm accuracy (Metav IndustryLine)

Measuring Ball Si3N4 30 mm is a ceramic precision sphere designed as a reference element for gauges, calibration setups and high-accuracy inspection tasks in industrial metrology and workshop quality control

• Ceramic Si3N4 high wear resistance
• Diameter 30 mm with tight tolerance
• Accuracy 0.003 mm precision
• Hardness HV1400–1700 for longevity

Reliable reference for high-precision calibrations

The ceramic sphere serves as a stable reference element for comparators, gauge blocks and repeatability checks. The specified 0.003 mm accuracy and diameter tolerance of 0.00008 mm translate into clearly defined measurement uncertainty when used as a master artefact. This predictability supports process control and traceable calibration routines, reducing ambiguity in measurement chains and enabling consistent documentation of results.

Material benefits that preserve measurement integrity

Made from Si3N4 ceramic, the sphere combines low density with excellent wear resistance and thermal stability. The high hardness (HV1400–1700) keeps contact surfaces dimensionally stable under repeated probing, while the very low surface roughness (0.00001 mm) minimises local deformation at contact points. These material properties reduce drift over time and help maintain repeatability across inspection cycles, so reference readings remain dependable without frequent requalification.

Practical fit for workshop and laboratory workflows

With a compact 30 mm diameter and modest mass, the sphere is straightforward to handle and position in fixtures or on probe stands. Its geometry makes it compatible with tactile and optical probe systems, enabling cross-checks between measurement technologies. When incorporated into routine checks, the component shortens verification intervals and supports quicker acceptance of parts—benefits that aid both production throughput and quality assurance.

Traceability and documentation in use

The sphere’s defined tolerance and accuracy facilitate integration into documented calibration chains and quality records. Lab personnel and workshop technicians gain a measurable baseline for instrument behaviour: deviations can be quantified against the sphere’s specification, informing corrective calibration actions. Clear numeric data on accuracy and tolerance also assist in selecting appropriate measurement strategies for specific inspection tasks.
