Gauge sphere pair M318.454 — 24 mm hardened chrome steel, 0.003 mm accuracy (Metav IndustryLine)

The gauge sphere pair M318.454 is a compact reference set designed for high-precision comparative measurements and gauging applications in workshop and laboratory environments.

• Hardened chrome steel > HRC 62
• Diameter 24 mm for compact references
• Accuracy 0.003 mm for traceable checks
• Supplied as a matched pair, 2 pieces

Repeatable reference performance for quality control

The matched pair delivers consistent comparative results thanks to a defined accuracy of 0.003 mm and a tight diameter tolerance of 0.00008 mm. Spherical artefacts with such reproducible dimensions serve as stable references for comparative checks, alignment tasks and functional gauge verification. The exceptionally low surface roughness (0.00001) supports contact-based measurements by reducing local surface effects, which in turn improves the repeatability of touch probe readings and mechanical comparators. In practice, the spheres act as a simple, robust baseline when validating measuring fixtures or verifying the performance of tactile sensors in production environments.

Durability and material properties that reduce downtime

Constructed from hardened chrome steel with a hardness above HRC 62, the spheres are engineered for long service life under repeated contact and handling. The choice of hardened material minimises wear and dimensional drift during routine use, so calibration intervals can be extended compared with softer reference artefacts. This combination of hardness and fine surface finish results in a component that maintains form under regular loading, supporting uninterrupted inspection routines and lowering the risk of unexpected rework or measurement uncertainty caused by surface degradation.

Compact format and practical workshop integration

With a 24 mm diameter and a set weight of approximately 0.2 kg, the pair is small enough for bench-top use yet large enough to provide stable contact with common measuring probes and fixtures. Supplied as a matched pair, the spheres are intended for direct comparative tasks or for creating simple kinematic contacts in fixture checks and go/no-go assemblies. The compact form factor also simplifies storage and handling in busy production or calibration areas where space is at a premium. Their geometry makes them suitable for use with three-point seats, V-blocks and precision adapters without extensive set-up time.
