This component features a cast zinc body measuring 2 inches in overall length with a 3\/4-inch diameter nylon roller and a 1\/4-inch face width. The nylon roller provides smooth, low-friction actuation against cams, dogs, or actuating surfaces in automated or safety-interlock applications. Licensed electricians and industrial maintenance technicians typically install or replace this part when the original roller shows wear, cracking, or binding that affects switch response accuracy.\u003c\/p\u003e\n\u003cp\u003eThis lever roller is suited for limit switch assemblies used in light industrial machinery, conveyor systems, material handling equipment, and other automated control applications where a roller-style actuator is required. It is intended as an accessory or replacement component for compatible limit switch bodies and is sold individually as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast zinc body construction for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003eNylon roller material for smooth, low-wear actuation\u003c\/li\u003e\n  \u003cli\u003e2-inch overall length fits standard lever roller mounting configurations\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch roller diameter with 1\/4-inch face width for consistent cam engagement\u003c\/li\u003e\n  \u003cli\u003eDesigned as a Switch Accessory replacement component for limit switch assemblies\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit with no minimum order beyond one piece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with limit switches as a replacement lever roller accessory.

De-energize and lock out the control circuit before removing or installing any limit switch components, following NFPA 70E lockout\/tagout procedures. Verify that the roller diameter and face width are compatible with the existing actuating cam or dog geometry before final assembly. Do not force the roller onto the lever arm; confirm all fasteners are secure before returning the circuit to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Accessory Type\u003c\/strong\u003e: Lever Roller\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoller Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoller Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: SQUARE D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7A4N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541364048178,"sku":"7A4N","price":62.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/240d3bdde9e2985057957319a50b1db3.jpg?v=1785873597","url":"https:\/\/voomisupply.com\/products\/square-d-7a4n-limit-switch-lever-roller-2-in-cast-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
