Built with Fiber-Reinforced Vytracord construction, this belt delivers reliable flex and load capacity under demanding operating conditions. The cogged profile reduces bending resistance, which improves efficiency and reduces heat buildup compared to a standard wrapped belt. It carries an outside length of 69 inches and an internal length of 67.80 inches, making it the BX66 belt designation. HVAC technicians, millwrights, and mechanical contractors are the primary installers of this belt type.\u003c\/p\u003e\n\u003cp\u003eThis belt is suited for residential and light commercial HVAC systems, agricultural equipment, compressors, fans, blowers, and general industrial drive setups that use BX-section sheaves. The Torque-Flex style construction handles dynamic loads and high-speed applications where standard belts may slip or wear prematurely. Its oil-resistant compound resists degradation in environments where incidental fluid contact is common, such as compressor rooms or mechanical equipment areas. The belt operates across a wide temperature range, from -40 degrees F to approximately 140 degrees F, supporting use in both cold-start and high-ambient conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBX-section cogged profile reduces bending resistance and heat buildup compared to standard wrapped belts\u003c\/li\u003e\n  \u003cli\u003eFiber-Reinforced Vytracord construction provides high tensile strength and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eOil-resistant compound protects against premature degradation in fluid-exposed environments\u003c\/li\u003e\n  \u003cli\u003eTorque-Flex style design handles dynamic and high-torque drive loads\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range: -40 degrees F minimum to approximately 140 degrees F maximum\u003c\/li\u003e\n  \u003cli\u003eOutside length of 69 inches with 67.80-inch internal length matches BX66 belt specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for BX66-designation cogged V-belts used in BX-section sheave and pulley drive systems across HVAC, agricultural, and general industrial power transmission applications.\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. Disconnect and lock out all power to the drive system before removing the old belt or installing the new one. Never force a belt onto a sheave using a pry bar, as this can damage the cord structure and reduce belt life. Adjust drive center distance to achieve proper tension according to the equipment manufacturer's specifications, and re-check tension after the first few hours of operation.\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: BX66\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: 69 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Length\u003c\/strong\u003e: 67.80 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: 0.8 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: 20039579\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CONTINENTAL","offers":[{"title":"Default Title","offer_id":51559873904946,"sku":"20039579","price":48.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3205e2cb266f21d1f493045fffff152.jpg?v=1786443168","url":"https:\/\/voomisupply.com\/products\/continental-contitech-20039579-bx-cogged-v-belt-69-in","provider":"Voomi Supply","version":"1.0","type":"link"}
