The roller arm measures 1.5 inches in length with a 0.25 inch diameter, and features a cast zinc body paired with a nylon roller for smooth, reliable actuation. The nylon roller provides consistent contact across a 0.25 inch face width. This part is installed by electricians and control system technicians when replacing worn or damaged actuator hardware on existing limit switch assemblies. It is a direct-fit accessory that restores proper mechanical actuation without requiring full switch replacement.\u003c\/p\u003e\n\u003cp\u003eThe 7B1N roller lever is suited for limit switch installations in industrial control panels, conveyor systems, machinery guarding, and automated equipment where precise mechanical triggering is required. The cast zinc body offers durability in light-duty to moderate-duty environments. This accessory is appropriate for both new installations and field service replacements on compatible SQUARE D limit switch bodies.\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-friction actuation\u003c\/li\u003e\n  \u003cli\u003e1.5 inch overall length for proper lever geometry on compatible switch bodies\u003c\/li\u003e\n  \u003cli\u003e0.25 inch roller diameter with 0.25 inch face width\u003c\/li\u003e\n  \u003cli\u003eSingle-piece accessory — no additional hardware included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement lever roller accessory for compatible SQUARE D limit switches requiring a 1.5 inch lever roller with cast zinc body and nylon roller.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed electrician or qualified control technician. De-energize and lock out the circuit before servicing any limit switch or its actuator components, following OSHA lockout\/tagout procedures and applicable NEC guidelines. Verify the replacement roller geometry matches the original actuator arm before finalizing installation. Do not force the roller onto the pivot shaft — inspect the mounting point for wear before reassembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoller Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 0.25 inches\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\u003eSwitch Accessory Type\u003c\/strong\u003e: Lever Roller\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: 0.1 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: 7B1N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51543585358130,"sku":"7B1N","price":44.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/240d3bdde9e2985057957319a50b1db3_1623dca7-8860-48c5-b0bf-6293cda160ca.jpg?v=1785920722","url":"https:\/\/voomisupply.com\/products\/square-d-7b1n-limit-switch-lever-roller-cast-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
