Gauge ball pair M318.419 — hardened chrome‑steel, 9 mm, 0.003 mm accuracy (Metav IndustryLine)

The Gauge ball pair M318.419 is a compact 9 mm hardened chrome‑steel set designed as a high‑precision reference for gauging, alignment and measurement fixtures in inspection and production environments.

• 9 mm hardened chrome‑steel balls
• Precision tolerance 0.00008 mm
• Accuracy 0.003 mm
• Supplied as a set of two

Reliable reference for high-precision measurement

The pair provides a stable, reproducible reference surface for coordinate measurement machines, tactile probing systems and optical comparators. With a declared accuracy of 0.003 mm and a diameter tolerance of 0.00008 mm, the spheres enable repeatable contact points that reduce uncertainty in positional checks. The extremely fine surface finish (0.00001 as supplied) minimises local measurement artefacts and supports consistent probing behaviour during cyclic inspection routines.

Durable material and dimensional stability

Manufactured from hardened chrome steel and rated at >HRC 62, the balls resist wear and maintain geometry under frequent contact. This hardness level ensures dimensional stability where repetitive probing or preloaded contact occurs, extending service intervals and lowering replacement frequency. Their compact 9 mm diameter combines rigidity with small footprint, making the spheres suitable for confined fixtures and fine‑feature reference duties without compromising stiffness.

Simple integration into metrology workflows

Delivered as a set of two, the pair can be used for comparative checks, alignment between two datum points or as matched references in bespoke fixtures. The modest mass contributes to easy handling while preserving thermal behaviour suitable for shopfloor and laboratory conditions. Traceability is supported by the product identifiers and packaging, facilitating inventory and quality records for inspection processes — a practical choice when repeatability and process reliability are priorities.
