It features an 8 mm ruby ball tip mounted on a ceramic stem with an overall length of 100 mm and an M4 threaded shank for direct attachment to compatible CMM probe modules. Ruby is the standard material for high-precision stylus balls due to its hardness and dimensional stability, making this stylus well suited for repeated contact scanning and touch-trigger measurements where tip wear and geometric accuracy are critical.\u003c\/p\u003e\u003cp\u003eThis stylus is intended for use in metrology environments where precise dimensional inspection is performed on machined parts, castings, and assemblies. The M4 thread is a widely used interface in CMM stylus systems, allowing installation on a broad range of probe bodies and extension combinations. It is typically installed by metrology technicians and quality control professionals in manufacturing, aerospace, automotive, and precision machining facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8 mm ruby ball tip for wear resistance and dimensional stability during contact measurement\u003c\/li\u003e\n\u003cli\u003eCeramic stem construction reduces thermal expansion effects and keeps stylus mass low\u003c\/li\u003e\n\u003cli\u003e100 mm overall length provides reach for recessed features and deep bores\u003c\/li\u003e\n\u003cli\u003eM4 threaded shank for compatibility with standard CMM probe bodies and styli systems\u003c\/li\u003e\n\u003cli\u003eSingle-piece package quantity suitable for direct replacement or kit supplementation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or supplemental stylus for CMM probe systems accepting M4 threaded ball styli.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCMM styli should be installed and removed by qualified metrology technicians using the appropriate stylus wrench to avoid overtightening the M4 thread. The probe head should be parked or the CMM powered to a safe state before changing styli. Handle the ruby ball tip carefully to avoid chipping, as contact damage will affect measurement accuracy. After installation, perform a stylus qualification routine on the CMM controller before beginning inspection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 100 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: Ceramic\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\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-5000-7796\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":67906384068914,"sku":"A-5000-7796","price":175.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91b45afdd14578845742c8b2219aca4b.jpg?v=1791167747","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5000-7796-cmm-ball-stylus-8mm-ruby-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
