Measurement ball pair M318.454 — 24 mm gauge spheres, 0.003 mm accuracy (Metav IndustryLine)

A matched pair of 24 mm gauge spheres crafted for precision gauge setting, comparative checks and reference measurements in metrology contexts.

• Precision grade: 0.003 mm accuracy
• Hardened chrome steel, >HRC 62
• 24 mm diameter with 0.00008 mm tolerance
• Supplied as a matched pair, 2 pieces

Pinpoint accuracy for critical checks

The pair delivers an accuracy of 0.003 mm, which translates into a dependable reference for fine-tuning gauges and verifying machine runout. Such resolution makes it possible to detect minimal deviations that would otherwise affect assembly fits or running clearances, reducing rework and downtime. The specified diameter tolerance of 0.00008 mm ensures consistency between the spheres, so comparative measurements remain meaningful when used in paired setups or comparator fixtures.

Durable construction for repeatable results

Manufactured from hardened chrome steel with hardness exceeding HRC 62, the spheres are engineered for long service life and resistance to surface wear under regular metrology use. The exceptionally low surface roughness (0.00001) minimises contact-induced measurement noise and supports stable, repeatable interfaces with probes and contact points. Together, material choice and finish create a robust reference element that maintains geometry and accuracy over many inspection cycles.

Matched pair format that speeds up inspection work

Supplied as a matched two-piece set with a nominal diameter of 24 mm, the spheres are ready for immediate integration into gauge blocks, calibration rigs or fixture references. The matched pairing removes the need for time-consuming sorting, allowing faster setup and consistent comparative readings. Their compact form and modest mass (0.2 kg per set) simplify handling and make them suitable as portable references between bench and workshop environments.

Practical advantages and application fit

These gauge spheres excel where small tolerances matter: setting plug gauges, checking spindle runout, or serving as reference points in inspection fixtures. The combination of tight dimensional control and a hardened, low-friction surface supports both short-term test cycles and longer-term traceability in production environments. Where reproducibility and low measurement uncertainty are priorities, the matched spheres provide a stable baseline that complements existing measuring equipment.
