Gauge Ball Pair M318.423 — hardened chrome steel, 13 mm, 0.003 mm accuracy

A Gauge Ball Pair designed for precision alignment, calibration and comparative inspection work in metrology and quality control environments.

• Hardened chrome steel for long-term stability
• Diameter 13 mm with 0.003 mm accuracy
• Matched pair for comparative measurements

Measured precision that reduces rework

The pair of precision spheres offers an industrial-grade accuracy of 0.003 mm, making it suitable where repeatable reference points are required. The nominal 13 mm diameter and the fine diameter tolerance of 0.00008 mm ensure that contact points remain consistent across fixtures and comparators, which reduces the need for corrective machining. Using stable reference spheres shortens inspection cycles and supports faster decision-making during first-article inspections or setup procedures.

Robust construction for dependable results

Manufactured from hardened chrome steel with a hardness exceeding HRC 62, the spheres resist wear and preserve geometry under repeated contact. A very fine surface roughness (0.00001 mm) contributes to minimal contact deformation and stable readings when used with dial indicators, electronic probes or optical comparators. The combination of high hardness and superb finish extends service life and maintains accuracy across production batches, delivering measurable cost-efficiency over time.

Clear application scope and simple handling

Delivered as a matched set of two, the spheres are prepared for comparative and reference tasks such as alignment, gauge setting and fixture verification in machining, toolroom and inspection labs. At approximately 0.05 kg per set, the components are easy to handle and integrate into existing workflows; their compact size makes them practical for both bench use and portable inspection rigs. The matched nature of the pair provides immediate interchangeability for comparative checks without additional sorting.
