Pair of measuring balls, hardened chrome steel – 25 mm, 0.003 mm accuracy (Metav IndustryLine)

A pair of 25 mm hardened chrome‑steel measuring balls for precision gauging, calibration and reference checks in workshop and inspection environments.

• High accuracy: 0.003 mm
• Hardened chrome steel > HRC 62
• Supplied as a precision set of 2

Precise reference values that stabilise quality control

The pair of gauging spheres provides a constant, reproducible contact geometry ideal for comparative checks and calibration tasks. With a stated accuracy of 0.003 mm and a diameter tolerance of 0.00008 mm, these spheres serve as reliable master references when aligning fixtures, verifying instrument repeatability or establishing form‑measuring baselines. The extremely low surface roughness (0.00001 mm) reduces measurement scatter by limiting microscopic asperity effects; the result is more consistent readings across repeated measurements. Such technical accuracy supports faster decision‑making in inspection loops and strengthens traceability in quality documentation.

Robust construction for long service life in industrial use

Manufactured from hardened chrome steel, the spheres resist wear and preserve dimensional integrity under frequent contact with probes and styluses. A hardness rating exceeding HRC 62 indicates high resistance to abrasion and deformation, which translates into fewer replacements and stable reference behaviour over time. Supplied as a precision set of two, the pair is useful for comparative checks or for use in fixtures where matched spheres are required. The compact 25 mm diameter balances ease of handling with sufficient contact area for tactile probes, making the set practical for bench and machine‑side use.

Practical handling and integration into inspection workflows

Each sphere is lightweight and compact, promoting straightforward placement in gauges, seats or jigs; the set weight facilitates manual handling while maintaining a feel suitable for delicate positioning. Typical applications include use as reference masters for comparative gauges, alignment jigs and contact‑probe verification on measuring machines. The simple geometry of a sphere provides a clear definition of the contact point, easing interpretation of measurements and reducing operator uncertainty. Delivered as a matched pair, the components are ready for immediate integration into routine inspection procedures or laboratory checks.

FAQ

What is the declared accuracy of the measuring‑ball pair?
The measuring‑ball pair is specified with an accuracy of 0.003 mm, suitable for precise reference and comparative measurements in inspection tasks.

What material and hardness are the spheres supplied in?
The spheres are made of hardened chrome steel with a hardness rating greater than HRC 62, ensuring high wear resistance during repeated use.

How is the product delivered and how many pieces are included?
The product is supplied as a precision set of 2 matched measuring balls for paired or comparative applications.

For which inspection tasks are the 25 mm spheres best suited?
The 25 mm size is ideal for fixture alignment, probe verification and use as gauge masters where a stable, reproducible contact point is required.

How stable is the surface finish and why does that matter?
With a surface roughness of 0.00001 mm, the finish minimises micro‑asperity effects, improving repeatability and reducing noise in contact measurements.
