It features a 4 mm ruby ball tip mounted on a carbon fiber stem with an M2 threaded connection. The overall length is 50 mm (1.9685 inches), and the stem diameter measures 3 mm (0.1181 inches). Ruby is the preferred ball material for CMM styli because of its hardness and dimensional stability, which supports repeatable contact measurements. The carbon fiber stem minimizes deflection and thermal expansion, contributing to consistent probe performance. This stylus is installed by metrology technicians and CMM operators in quality control and inspection environments.\u003c\/p\u003e\u003cp\u003eThis stylus is suited for inspection tasks on CMM systems that accept M2 threaded probe connections. It is appropriate for both shop-floor and lab-based CMM setups where a 4 mm ball diameter is required for feature access and measurement accuracy. Typical applications include dimensional inspection of machined parts, tooling verification, and geometric tolerancing in manufacturing and quality assurance workflows. The 50 mm overall length provides adequate reach for standard surface and bore measurements without excessive overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 mm ruby ball tip for hard, dimensionally stable contact measurement\u003c\/li\u003e\n\u003cli\u003eCarbon fiber stem reduces deflection and thermal growth during use\u003c\/li\u003e\n\u003cli\u003eM2 threaded connection for compatibility with M2 CMM probe systems\u003c\/li\u003e\n\u003cli\u003e50 mm overall length (1.9685 inches) suits standard inspection reach requirements\u003c\/li\u003e\n\u003cli\u003e3 mm stem diameter (0.1181 inches) balances rigidity and clearance access\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard stylus for CMM systems that accept M2 threaded ball styli.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCMM styli are installed and removed by metrology technicians or CMM operators. Power down or pause the CMM and retract the probe head before changing styli to avoid damage to the probe mechanism. Handle the ruby ball with care and avoid contact with abrasive surfaces, as even minor damage to the ball geometry will affect measurement accuracy. Consult the CMM manufacturer's documentation for recommended seating torque and qualification procedures after stylus installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 4 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Material\u003c\/strong\u003e: Ruby\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50 mm (1.9685 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective Working Length\u003c\/strong\u003e: 50 mm (1.9685 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 3 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Material\u003c\/strong\u003e: Carbon Fiber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStylus Type\u003c\/strong\u003e: Ball\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-5003-2285\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":67917962051890,"sku":"A-5003-2285","price":143.15,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/698ea640bb186fd80536cce333462308.jpg?v=1791266431","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5003-2285-cmm-ball-stylus-4mm-ruby-m2","provider":"Voomi Supply","version":"1.0","type":"link"}
