It features a 6 mm ruby ball tip mounted on a ceramic stem with an M4 threaded shank, giving it an overall length of 150 mm (approximately 5.906 inches). The ruby ball provides excellent hardness and wear resistance for repeatable contact measurements. The ceramic stem minimizes thermal expansion and deflection during probing cycles. This stylus is installed by metrology technicians and CMM operators in precision measurement environments.\u003c\/p\u003e\n\u003cp\u003eThis stylus is suited for use in dimensional inspection applications where accurate surface contact measurement is required. The M4 thread allows it to mount directly to compatible Renishaw probe bodies and extension modules. It is commonly used in both production-floor CMM setups and dedicated metrology labs for measuring machined components, tooling, and assemblies. The 150 mm overall length makes it appropriate for applications requiring extended reach into bores, pockets, or recessed features.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6 mm ruby ball tip for high wear resistance and consistent contact point geometry\u003c\/li\u003e\n  \u003cli\u003eCeramic stem reduces thermal expansion effects and styli deflection\u003c\/li\u003e\n  \u003cli\u003eM4 threaded shank for direct mounting to compatible probe bodies and extensions\u003c\/li\u003e\n  \u003cli\u003e150 mm overall length provides extended reach for recessed or deep-feature measurement\u003c\/li\u003e\n  \u003cli\u003eLightweight construction minimizes probe head loading during high-speed scanning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement stylus for CMM probe systems accepting M4-threaded ball styli.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCMM styli are installed and qualified by metrology technicians or CMM programmers. Before changing a stylus, ensure the CMM is in a safe parked position and the probe head is stationary. Use the appropriate torque-limiting stylus tool when threading the M4 shank to avoid damaging the probe body threads. After installation, run a full stylus qualification routine on the CMM controller before using the new stylus for measurement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 150 mm (approximately 5.906 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: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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-5000-8156\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":67907337748786,"sku":"A-5000-8156","price":219.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6d8cfda085712edef95bfbedf697032.jpg?v=1791177634","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5000-8156-cmm-ball-stylus-6mm-ruby-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
