Gauge ball pair M318.452 — precision 22 mm reference spheres, hardened chrome steel

Gauge ball pair M318.452 provides a compact, high-accuracy reference for gauging and setup tasks across inspection benches and fixture verification.

• Hardened chrome steel for wear resistance
• Precision 0.003 mm for high-accuracy gauging
• Diameter 22 mm for standardised reference
• Supplied as a matched pair for comparative checks

Durable material and measurable benefits for routine metrology

Constructed from hardened chrome steel, these precision spheres deliver long service life and stable dimensions under repeated handling. The combination of HRC 62 hardness and a finely finished surface with 0.00001 mm roughness reduces plastic wear and surface alteration, so the reference remains reliable over many cycles. For production lines and quality laboratories, that durability translates into fewer replacements and consistent gauging results, supporting efficient throughput and less downtime.

Accuracy and traceability that support decision making

With a stated accuracy of 0.003 mm and a diameter tolerance of 0.00008 mm, the pair functions as a trustworthy reference standard for comparative checks and fixture alignment. The small mass and compact geometry mean the spheres are easy to position in gauge holders or on flat datum surfaces, enabling reproducible setups. In practical terms, these characteristics make the pair suitable for routine dimensional checks where tight tolerances and quick verification are required.

Practical handling and application scenarios

Supplied as a matched set of two spheres, the product is optimised for comparative measurement tasks—such as checking runout, verifying ball-seat fits or establishing reference points in coordinate measurements. The 22 mm size is widely compatible with standard gauge fixtures and tactile probes, offering an immediate fit into existing workflows. Lightweight construction ensures straightforward manual handling while the high hardness preserves form under contact with hardened gauge tooling.

Quality signals and suitability for industrial use

The compact pair is designed for industrial metrology use where a robust, repeatable reference component is preferred over delicate standards. The 22 mm diameter and matched-pair delivery support comparative procedures and quick interchangeability. As part of a broader quality assurance routine, these spheres contribute to traceable measurement chains and help to maintain consistent inspection criteria across shifts and machines.
