Measuring Ball & Ball Gauge Set | ULTRA Shop

Buy high-precision individual measuring balls and ball gauges with handles made of chrome steel, stainless steel, or tungsten carbide as reliable auxiliary standards for dimensional metrology online.

Measuring balls and ball gauges serve as indispensable aids for precise internal and geometric measurements in manufacturing and quality inspection. They are ideally suited for accurate bore testing, determining internal cones, undercuts, as well as indirect distance measurement on difficult-to-access geometries. Due to the mathematically precisely defined point-gauging principle, form deviations and dimensional tolerances can be reliably determined directly on the machine tool or in the measuring room.

Our B2B portfolio offers maximum flexibility for your gauge monitoring: choose between ball systems made of through-hardened chrome steel, corrosion-resistant stainless steel, or extremely wear-resistant tungsten carbide for maximum tool life with abrasive test specimens. The measuring instruments are available as individually calibrated test bodies in the nominal size range from Ø 0.5 mm to 30.0 mm with tightest tolerances of up to ±0.001 mm. For systematic application, we stock ergonomic ball gauges with handles as well as complete, multi-piece ULTRA measuring ball sets in protective wooden cases or from the ULTRA active series. All standards guarantee seamless traceability for your quality assurance through optional factory or DAkkS calibration certificates.
