It features a 5 mm ruby ball tip mounted on a ceramic stem with an M2 threaded connection. The overall length is 50 mm (approximately 1.969 inches), and the stem diameter measures 2.5 mm (approximately 0.098 inches). Ruby is the standard material choice for CMM contact points due to its hardness and dimensional stability. This stylus is installed by metrology technicians and CMM operators in dimensional inspection environments.\u003c\/p\u003e\u003cp\u003eThis stylus is suited for precision measurement tasks on coordinate measuring machines in manufacturing, quality control, and inspection departments. The M2 thread is a common interface on Renishaw-compatible probe heads and extension systems. Its 50 mm effective working length makes it appropriate for accessing recessed features, bores, and surfaces that require moderate stylus reach without excessive deflection. Typical applications include part qualification, first-article inspection, and in-process gauging in both production and tool-room settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5 mm ruby ball tip for precise, low-wear contact measurement\u003c\/li\u003e\n\u003cli\u003eCeramic stem reduces thermal expansion and keeps stylus mass low\u003c\/li\u003e\n\u003cli\u003eM2 thread fits standard CMM probe head interfaces\u003c\/li\u003e\n\u003cli\u003e50 mm overall length provides moderate reach into recessed features\u003c\/li\u003e\n\u003cli\u003e2.5 mm stem diameter balances rigidity with clearance in tight geometries\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CMM probe heads and extension systems that accept M2 threaded styli, consistent with Renishaw-compatible probing configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCMM styli should be installed and torqued by qualified metrology personnel following the CMM manufacturer's recommended procedures. Always power down or pause the CMM and clear the probe path before changing styli. Avoid touching the ruby ball with bare hands, as skin oils can affect measurement accuracy. After installation, perform a qualifying run with the CMM's calibration sphere before beginning part measurement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 5 mm (0.1969 inches)\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: 2.5 mm (0.0984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\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-5003-0066\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":67908681236786,"sku":"A-5003-0066","price":122.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b9d94bda6ae1a0925093c04ea4285e3.jpg?v=1791184396","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5003-0066-cmm-ball-stylus-5mm-ruby-m2","provider":"Voomi Supply","version":"1.0","type":"link"}
