Constructed from Fiber Reinforced Vytracord, this Torque-Flex belt features a cogged profile that reduces bending stress, increases flexibility, and improves heat dissipation compared to standard wrapped belts. It measures 54.0 inches outside length with a 52.80-inch internal length and weighs 0.6 pounds. The oil-resistant compound makes it suitable for environments where incidental fluid exposure is likely.\u003c\/p\u003e\n\u003cp\u003eThis BX51 belt is used in belt-driven blower assemblies, fan drives, compressors, and pump systems found in residential and light commercial HVAC units, as well as general-purpose industrial drive applications. The cogged construction allows use on smaller sheave diameters without the excessive heat buildup common in solid-back belts, making it a preferred replacement in high-cycle or high-load drive systems. HVAC technicians and mechanical contractors are the typical installers for this type of belt.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCogged BX-section profile reduces bending resistance and extends belt service life on smaller pulleys\u003c\/li\u003e\n  \u003cli\u003eFiber Reinforced Vytracord construction provides high tensile strength and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eOil-resistant compound withstands incidental exposure to lubricants and fluids\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range from -40 degrees F to 140 degrees F (-40 C to 60 C)\u003c\/li\u003e\n  \u003cli\u003eTorque-Flex design accommodates variable-speed and high-torque drive applications\u003c\/li\u003e\n  \u003cli\u003e54.0-inch outside length corresponds to standard BX51 belt designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct OEM-style replacement for BX51 belt applications using BX-section sheaves in residential and commercial HVAC blower drives, fan systems, and general industrial power transmission equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBelt replacement should be performed by a qualified HVAC technician or mechanical contractor with the drive system fully de-energized and locked out per OSHA lockout\/tagout procedures. Never pry or force the belt onto sheaves; always release drive tension by adjusting the motor mount before installing or removing the belt. Inspect sheaves for wear, misalignment, and proper groove profile before installing a new belt. Tension the belt according to the equipment manufacturer's deflection specification to avoid premature wear or belt slip.\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: BX51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Style\u003c\/strong\u003e: Cogged V-Belt (Torque-Flex)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Length\u003c\/strong\u003e: 54.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Length\u003c\/strong\u003e: 52.80 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 (140 degrees F)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees C (-40 degrees F)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: 20039564\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CONTINENTAL","offers":[{"title":"Default Title","offer_id":51559714029874,"sku":"20039564","price":45.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dda704b9cd49da8845dd0f40ee69669.jpg?v=1786438904","url":"https:\/\/voomisupply.com\/products\/continental-contitech-20039564-bx51-cogged-v-belt-bx-section","provider":"Voomi Supply","version":"1.0","type":"link"}
