It features a 2 mm ruby ball mounted on a stainless steel stem with an M2 thread connection, providing the dimensional accuracy and surface hardness that CMM probing applications demand. The ruby ball delivers consistent contact repeatability and resistance to wear across high-cycle measurement routines. With an overall length of 20 mm and an effective working length of 7.37 mm, this stylus suits a wide range of part geometries encountered in precision inspection work. Metrology technicians and quality lab professionals install and use this stylus as part of touch-trigger or scanning probe systems.\u003c\/p\u003e\n\u003cp\u003eThis stylus is intended for dimensional inspection tasks in quality control environments, tool rooms, and metrology labs. It is suited to measuring bores, surfaces, and features on machined components where a 2 mm ball diameter provides access to small or tight geometry. The M2 thread allows direct mounting to compatible probe bodies and extension combinations. It is appropriate for both manual and CNC-driven CMM applications in light manufacturing, aerospace, automotive, and general precision machining settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2 mm ruby ball for precise, repeatable contact measurement\u003c\/li\u003e\n  \u003cli\u003eStainless steel stem with 1.78 mm stem diameter for rigidity and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eM2 thread for direct connection to compatible CMM probe bodies and extensions\u003c\/li\u003e\n  \u003cli\u003e20 mm overall length with 7.37 mm effective working length\u003c\/li\u003e\n  \u003cli\u003eRuby ball material provides high hardness and wear resistance for extended stylus life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or supplemental stylus for CMM probe systems accepting M2 threaded styli.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by metrology technicians or quality lab personnel. The probe head or module should be removed from active measurement and the CMM placed in a safe parked state before changing styli. Hand-tighten the M2 thread using the appropriate stylus wrench to avoid cross-threading or over-torquing the ruby ball mount. After installation, perform a full stylus qualification routine on the CMM controller before returning the system to production measurement use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStylus Type\u003c\/strong\u003e: Sphere\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 2 mm (0.08 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEffective Working Length\u003c\/strong\u003e: 7.37 mm (0.29 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 1.78 mm (0.07 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Material\u003c\/strong\u003e: Ruby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111900\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RENISHAW\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A-5000-7812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":67914484613426,"sku":"A-5000-7812","price":193.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ca000e42d64aa0bdfd60647a5812eb2.jpg?v=1791249509","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5000-7812-cmm-sphere-stylus-2mm-ruby-m2","provider":"Voomi Supply","version":"1.0","type":"link"}
