It features a 5 mm ruby ball tip mounted on a ceramic stem with an M4 threaded shank, giving it a 100 mm overall length. Ruby is the standard choice for CMM styli because of its hardness, dimensional stability, and low wear rate against most workpiece materials. The ceramic stem reduces thermal expansion effects and keeps the stylus lightweight, which helps maintain accuracy during repeated probing cycles. This stylus is installed by metrology technicians and quality control personnel in precision measurement environments.\u003c\/p\u003e\n\u003cp\u003eThis stylus is used in coordinate measuring machine setups for dimensional inspection of machined parts, castings, and assemblies in both production floor and lab environments. The M4 thread is a common interface on touch-trigger and scanning probe systems. The 100 mm overall length suits applications where reach into bores, pockets, or recessed features is required without excessive deflection. Sold individually, it is a direct replacement stylus for routine maintenance of CMM probe styli.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5 mm ruby ball tip for high hardness and low wear during contact probing\u003c\/li\u003e\n  \u003cli\u003eCeramic stem minimizes thermal growth and reduces overall stylus mass\u003c\/li\u003e\n  \u003cli\u003eM4 threaded shank for compatibility with standard CMM probe bodies\u003c\/li\u003e\n  \u003cli\u003e100 mm overall length provides reach into recessed workpiece features\u003c\/li\u003e\n  \u003cli\u003eSingle-piece replacement unit, sold individually\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement stylus for CMM probing systems that accept M4 threaded styli.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCMM styli should be installed and changed by qualified metrology technicians following the CMM manufacturer's probe qualification procedures. Power down or pause the CMM and disengage the probe head before removing or installing a stylus to avoid damaging the probe mechanism. Hand-tighten the M4 thread carefully to avoid cross-threading or over-torquing the stylus mount. After installation, re-qualify the stylus using the CMM's standard calibration sphere routine before resuming measurement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 5 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\u003ePackage Quantity\u003c\/strong\u003e: 1\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-5000-9761\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":67905960837426,"sku":"A-5000-9761","price":186.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/181cbd18dff0df9cb63025a2d1257a60.jpg?v=1791161015","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5000-9761-cmm-ball-stylus-5-mm-m4-ruby-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
