Gauge Ball Pair M318.425 — 15 mm, 0.003 mm accuracy (Metav IndustryLine)

A matched pair of precision gauge balls for calibration and dimensional inspection in metrology and gauge testing.

• Hardened chrome steel construction
• Diameter 15 mm for standard gauges
• Accuracy 0.003 mm for precision checks
• Supplied as a matched pair

Repeatable reference for high‑precision checks

The 15 mm precision spheres provide a stable reference for short‑range verification and comparative gauging. With an accuracy of 0.003 mm and a diameter tolerance of 0.00008 mm, these precision spheres minimise measurement deviation during repeat inspections. The surface roughness 0.00001 ensures low contact variability, while the >HRC 62 hardness rating delivers long‑term wear resistance; this combination reduces the frequency of replacement and supports consistent results in routine quality control.

Practical calibration and inspection benefits

Designed as a gauge ball pair, the set of two matched spheres simplifies comparative measurements and alignment procedures. Being supplied as a set of two allows for quick checks between a reference and the test item, helping to accelerate throughput without compromising traceability. The matched pairing also aids in detecting measurement system shifts, thereby contributing to lower process uncertainty and improved decision‑making in inspection workflows.

Compact handling with workshop readiness

The small footprint and modest mass (approx. 0.08 kg per set) make these spheres easy to handle in both bench and fixture‑based operations. Their hardened chrome steel composition provides mechanical stability and resistance to surface damage during routine use. For workshops and inspection labs seeking rugged, low‑maintenance reference elements, the matched pair offers a straightforward upgrade to existing gauge sets and inspection kits, supporting reliable dimension control with minimal setup time.
