It features a 2 mm ruby ball tip mounted on a solid carbide stem with a total overall length of 50 mm and an M4 threaded shank for direct attachment to CMM probe heads and extension modules. Ruby is a preferred ball material for CMM styli due to its hardness, low friction, and dimensional stability under repeated contact cycles. This stylus is installed and qualified by metrologists, quality technicians, and CMM programmers operating in manufacturing inspection environments.\u003c\/p\u003e\u003cp\u003eThis stylus suits a wide range of CMM inspection tasks including feature measurement, bore gauging, and surface scanning on precision components. The 50 mm overall length provides reach into moderately deep features without requiring additional extensions. The M4 thread is a standard CMM interface compatible with common probe head and stylus module systems used in dimensional inspection labs and production-floor CMM cells.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2 mm ruby ball tip for high-wear resistance and consistent contact point geometry\u003c\/li\u003e\n\u003cli\u003eSolid carbide stem for rigidity and minimal deflection during probing cycles\u003c\/li\u003e\n\u003cli\u003e50 mm overall length suits moderate-depth feature access\u003c\/li\u003e\n\u003cli\u003eM4 threaded shank for direct mounting to compatible CMM probe heads and modules\u003c\/li\u003e\n\u003cli\u003eRuby material provides low friction and long service life in repetitive contact applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit stylus for CMM systems accepting M4-threaded styli, consistent with standard probe head and stylus module interfaces used in coordinate measuring machine applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCMM styli should be installed and qualified by trained metrologists or CMM technicians following the machine manufacturer's qualification procedure. The probe head and any active scanning module must be in a safe, parked position before stylus exchange. Use the manufacturer-recommended torque tool or finger-tighten only per machine guidelines to avoid thread damage or seating error. After installation, always run a full stylus qualification routine before taking measurements to establish accurate ball center compensation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-5003-4797\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":67909741412658,"sku":"A-5003-4797","price":124.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7851aeefd3abe8404acfa9ff2ce2c5bf.jpg?v=1791190905","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5003-4797-cmm-ball-stylus-2mm-m4-ruby","provider":"Voomi Supply","version":"1.0","type":"link"}
