It features a 2 mm ruby ball tip mounted on a solid carbide stem with an M3 thread connection. The overall length is 40 mm (1.5748 inches), with an effective working length of 32.5 mm (1.2795 inches) and a stem diameter of 1.5 mm (0.0591 inches). Ruby is the preferred ball material for CMM styli because of its hardness and dimensional stability, making this stylus well suited for high-repeatability surface scanning and touch-trigger probing tasks. Installation and replacement are performed by metrology technicians and CMM operators in calibration labs and quality control environments.\u003c\/p\u003e\u003cp\u003eThis stylus is used in dimensional inspection setups where a small-diameter ball is required to access tight features, bores, or contoured surfaces. The M3 thread is a standard connection size compatible with Renishaw-style probe bodies and extension systems. It is appropriate for both manual and automated CMM probing routines in manufacturing quality control, tool and die inspection, and aerospace or automotive part verification workflows.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2 mm ruby ball tip for high hardness and low wear in repeated contact measurement\u003c\/li\u003e\n\u003cli\u003eSolid carbide stem provides rigidity and minimizes deflection during probing\u003c\/li\u003e\n\u003cli\u003eM3 thread connection is standard across a wide range of CMM probe bodies and stylus changers\u003c\/li\u003e\n\u003cli\u003e40 mm overall length with 32.5 mm effective working length for access to moderate-depth features\u003c\/li\u003e\n\u003cli\u003eCompact 1.5 mm stem diameter reduces obstruction in tight inspection areas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement stylus for CMM probe systems using M3 thread connections.

Power down or pause the CMM and retract the probe head before changing styli to avoid damage to the probe mechanism. Thread the stylus into the probe body by hand until snug, using only a stylus wrench if required  -  do not overtighten, as carbide stems and ruby balls are brittle. Recalibrate the probe qualification sphere after any stylus change to maintain measurement accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 2 mm (0.0787 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 40 mm (1.5748 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective Working Length\u003c\/strong\u003e: 32.5 mm (1.2795 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 1.5 mm (0.0591 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3\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: Carbide\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-5003-0053\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":67906849276210,"sku":"A-5003-0053","price":73.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d5892a5a2f6a4d0341d7addf0d7f8ea.jpg?v=1791172033","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5003-0053-cmm-ball-stylus-2mm-ruby-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
