It features a 3 mm ruby ball tip mounted on a solid carbide stem, with a 20 mm overall length. Ruby is the standard material for CMM styli because of its hardness, dimensional stability, and low wear rate against most workpiece surfaces. This stylus is used by metrologists, quality control technicians, and precision machining professionals who require accurate, repeatable surface contact during dimensional inspection routines.\u003c\/p\u003e\u003cp\u003eThis stylus is suited for standard CMM inspection work in manufacturing, tooling, and quality assurance environments. The 20 mm overall length and 3 mm ball diameter make it appropriate for general-purpose probing of machined parts, fixtures, and molds where moderate reach and fine contact geometry are required. It is a direct-mount stylus intended for use with compatible CMM probe heads in both automated scanning and touch-trigger measurement cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3 mm ruby ball tip for precise, low-wear surface contact\u003c\/li\u003e\n\u003cli\u003eSolid carbide stem provides rigidity and minimizes deflection during probing\u003c\/li\u003e\n\u003cli\u003e20 mm overall length suited for general-purpose CMM measurement tasks\u003c\/li\u003e\n\u003cli\u003eRuby ball material offers high hardness and dimensional consistency across repeated cycles\u003c\/li\u003e\n\u003cli\u003eCompact form factor compatible with standard CMM stylus mounting interfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-supply stylus for CMM probe heads that accept M2 or equivalent threaded ball styli; verify thread specification and probe head interface requirements before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified metrologist or CMM technician familiar with stylus change procedures for the specific probe head in use. Power down or place the CMM in a safe, parked state before changing styli to avoid probe crashes. Use the appropriate stylus-change tool or wrench as specified by the probe head manufacturer - do not overtighten, as carbide stems and ruby balls are brittle and can fracture under excess torque. After installation, perform a full stylus qualification routine to recalibrate ball center position before resuming measurement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 20 mm\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 pounds\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-5003-4793\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":68295480181042,"sku":"A-5003-4793","price":117.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccb32740e4b074aa6a2c82c2710923c7.jpg?v=1793696975","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5003-4793-cmm-ball-stylus-probe-3mm-ruby","provider":"Voomi Supply","version":"1.0","type":"link"}
