Repeatable reference surfaces for inspection and setup

High‑precision measurement spheres serve as reproducible contact points in a range of inspection workflows. With a nominal diameter of 10 mm and an indicated accuracy of 0.003 mm, the spheres reduce variability when used as reference elements in comparative measurements, fixture alignment or master gauge assemblies. The exceptional diameter tolerance (0.00008 mm) and very low surface roughness (0.00001) minimise local form errors and ensure consistent kinematic contacts, which in turn lowers measurement uncertainty and speeds up setup routines.

Hardened material for durability and long service life

Manufactured from hardened chrome steel with a hardness above HRC 62, the spheres resist wear and maintain roundness under repeated contact. This material choice supports longevity in workshop environments and preserves the integrity of the reference surface during routine handling and gauging cycles. The robust finish allows the spheres to withstand the mechanical stresses typical of gauge fixtures, ensuring reliable performance over time and fewer replacements—an efficiency gain for production and quality departments.

Practical delivery and compatibility with gauge systems

Delivered as a pair, the spheres are ready for integration into gauges, plug gauges, test stands or as tuning elements for measurement jigs. The low mass and compact form make them straightforward to mount or seat in locator pockets, while the precise tolerance and roughness data enable their use where tight control of contact geometry is required. For workshop planners and quality engineers, the combination of repeatability and material resilience offers a cost‑effective way to upgrade reference standards without complicated installation or calibration procedures.
