Gauge ball pair, 13 mm — hardened chrome steel, 0.003 mm accuracy (Metav IndustryLine)

Gauge ball pair, 13 mm is a compact set of precision measuring spheres designed for reference measurements, gauge setting and high‑accuracy inspection tasks in metrology and tooling.

• Hardened chrome steel >HRC 62
• Roundness precision 0.003 mm
• Diameter tolerance 0.00008 mm
• Compact 13 mm diameter spheres

Industrial-grade precision that secures measurement chains

The pair delivers a declared accuracy of 0.003 mm, making it suitable as a reference element in comparative checks and for stability tests on measuring machines. The stated diameter tolerance of 0.00008 mm and a surface roughness of 0.00001 mm indicate a highly uniform geometry and finish; this reduces form‑related uncertainty when used against gauge blocks, mandrels or inside precision fixtures. Such numbers translate into tighter repeatability for inspection routines and more reliable pass/fail decisions in a production environment.

Durable construction for repeatable results

Manufactured from hardened chrome steel, the spheres offer elevated wear resistance and dimensional stability under frequent contact. The material hardness >HRC 62 resists surface deformation during repeated probing or contact with hardened anvils, which preserves the reference quality over time and minimises the need for frequent replacement. The compact geometry and high‑quality finish also reduce measurement errors related to contact deformation or residue build‑up during routine use.

Compact format for versatile metrology tasks

At 13 mm diameter and supplied as a set of two, the spheres are easy to integrate into small gauges, comparator setups or as reference points for CMM probing tests. The low mass and small footprint support fine fixturing and make the pair well suited to bench‑top inspection and tooling checks where space is limited. Those seeking consistent, repeatable reference features for high‑precision assemblies will find the format convenient for both workshop and laboratory workflows.
