It features a 5 mm ruby ball tip mounted on a stainless steel stem with an M4 threaded shank, and has an overall length of approximately 100 mm (3.94 inches). Ruby is the preferred ball material for CMM styli due to its hardness, dimensional consistency, and resistance to wear during repeated contact measurement cycles. This stylus is installed by metrologists, quality technicians, and precision measurement professionals on CMM probe heads and touch-trigger probe systems.\u003c\/p\u003e\u003cp\u003eThis stylus is suited for dimensional inspection work in manufacturing and quality control environments. It fits standard M4-threaded CMM probe bodies and extension assemblies, making it compatible with a wide range of touch-trigger and scanning probe setups. Typical applications include part feature verification, bore measurement, surface profiling, and fixture checking on both small and medium-sized workpieces. It is used in both production floor CMM installations and dedicated metrology labs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5 mm ruby ball tip for wear resistance and repeatable contact measurement\u003c\/li\u003e\n\u003cli\u003eM4 threaded shank for secure attachment to compatible CMM probe bodies and extensions\u003c\/li\u003e\n\u003cli\u003e100 mm overall length (approximately 3.94 inches) for access to recessed or deep features\u003c\/li\u003e\n\u003cli\u003eStainless steel stem for rigidity and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSold individually (quantity of one per package)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit stylus for CMM probe systems accepting M4 threaded ball styli.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified metrologist or CMM technician familiar with probe qualification procedures. The stylus must be threaded in by hand until snug  -  do not overtighten, as excess torque can damage the probe head seating or alter stylus alignment. After installation, re-qualify the stylus on the CMM using the machine's standard qualification routine before taking measurements. Ensure the probe head is in a safe parked position before changing styli.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 (approximately 3.94 inches)\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: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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-5000-7522\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":67912506409266,"sku":"A-5000-7522","price":108.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99c1724a141e637d342ba06182f8112e.jpg?v=1791235413","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5000-7522-cmm-ball-stylus-5mm-ruby-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
