Built from fiber-reinforced Vytracord, this Torque-Flex belt delivers flexible power transmission with reduced bending resistance compared to standard wrapped belts. The cogged construction improves heat dissipation and allows use on smaller-diameter sheaves without sacrificing tensile strength. It is rated for operating temperatures from -40 degrees F to 140 degrees F (equivalent to -40 degrees C to 60 degrees C) and carries an oil-resistant rating, making it suitable for environments where lubricant exposure is a concern. HVAC technicians, mechanical contractors, and industrial maintenance professionals install this belt in drive systems requiring reliable, long-service power transfer.\u003c\/p\u003e\n\u003cp\u003eThis BX81 cogged V-belt is suited for use in residential and commercial HVAC blower drive systems, fan and pump drives, compressor drives, and general industrial power transmission applications. The BX section is a standard cross-section designation used across a wide range of drive configurations. It is a direct replacement for any BX81-spec belt in systems calling for a 84-inch outside-length cogged BX-section drive belt. Install locations typically include air handlers, rooftop units, belt-drive fans, and industrial equipment using standard V-belt sheaves.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCogged construction reduces bending stress and allows use on smaller sheave diameters\u003c\/li\u003e\n  \u003cli\u003eFiber-reinforced Vytracord material provides high tensile strength with flexible performance\u003c\/li\u003e\n  \u003cli\u003eOil-resistant rating for use in environments with incidental lubricant exposure\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range: -40 degrees C to 60 degrees C\u003c\/li\u003e\n  \u003cli\u003eTorque-Flex style design improves grip and load-carrying capacity in demanding drive systems\u003c\/li\u003e\n  \u003cli\u003eBX81 designation with 84-inch outside length and 82.80-inch internal length for precise fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for BX81 cogged V-belts in any drive system specifying a BX-section belt with an 84-inch outside length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBelt replacement should be performed by a qualified HVAC technician or mechanical maintenance professional. Disconnect and lock out power to the drive system before removing the old belt or adjusting sheave spacing. Do not pry the belt over sheave flanges; always release drive tension before installing or removing the belt. After installation, verify proper belt tension and sheave alignment per the equipment manufacturer's service documentation before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Section\u003c\/strong\u003e: BX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Number\u003c\/strong\u003e: BX81\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Style\u003c\/strong\u003e: Cogged (Torque-Flex)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Length\u003c\/strong\u003e: 84 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Length\u003c\/strong\u003e: 82.80 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fiber-Reinforced Vytracord\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResistance Features\u003c\/strong\u003e: Oil-Resistant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 60 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 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: CONTINENTAL CONTITECH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20039594\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CONTINENTAL","offers":[{"title":"Default Title","offer_id":51563658346802,"sku":"20039594","price":56.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7248055808942b528b1ccf1254fc38d.jpg?v=1786500481","url":"https:\/\/voomisupply.com\/products\/continental-contitech-20039594-bx81-cogged-v-belt-84-in","provider":"Voomi Supply","version":"1.0","type":"link"}
