Built with Fiber-Reinforced Vytracord construction, this Torque-Flex belt delivers flexibility and tensile strength under continuous load. The cogged underside reduces bending resistance and heat buildup, improving efficiency over standard wrapped belts. With a 161-inch outside length and a belt number of BX158, it is sized for large-frame drives common in blower assemblies, compressors, and heavy-duty fan systems. The oil-resistant compound extends service life in environments where lubricant contamination is a concern.\u003c\/p\u003e\n\u003cp\u003eThis belt is suited for residential and commercial HVAC systems, industrial fan and blower drives, pump drives, and agricultural equipment requiring a BX-section cogged belt. The BX158 designation makes it a direct replacement in drive systems originally spec'd for that belt number. Technicians working on large rooftop units, industrial air handlers, or commercial refrigeration condenser fans will find this belt an appropriate fit where BX-section drives are specified by the OEM.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBX-section cogged design reduces bending resistance and heat generation 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 resists degradation from incidental lubricant exposure\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range: -40 degrees F to approximately 140 degrees F (-40 degrees C to 60 degrees C)\u003c\/li\u003e\n  \u003cli\u003eTorque-Flex style allows use on smaller sheave diameters without sacrificing load capacity\u003c\/li\u003e\n  \u003cli\u003e161-inch outside length with BX158 belt number for straightforward cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis belt carries the BX158 belt number designation and is designed as a direct OEM-style replacement for drive systems specifying a BX-section cogged V-belt with a 161-inch outside length and 159.80-inch internal length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBelt replacement on drive systems should be performed by a qualified technician with the unit fully de-energized and locked out per NFPA 70E and applicable OSHA standards. Inspect sheaves for wear, misalignment, and debris before installing the new belt. Set belt tension according to the driven equipment manufacturer specifications using a belt tension gauge — do not over-tension, as this accelerates bearing wear. Never pry a V-belt over sheave flanges; always adjust center distance to allow proper seating.\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: BX158\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Style\u003c\/strong\u003e: Torque-Flex Cogged V-Belt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Length\u003c\/strong\u003e: 161 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Length\u003c\/strong\u003e: 159.80 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: 1.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 26111800\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: 20039635\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CONTINENTAL","offers":[{"title":"Default Title","offer_id":51558229967154,"sku":"20039635","price":103.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d8fa8f9a1f42cb89812c0c097feaf56_142aca99-b546-43dd-90e4-7772dabb87eb.jpg?v=1786406708","url":"https:\/\/voomisupply.com\/products\/continental-contitech-20039635-bx-cogged-v-belt-bx158","provider":"Voomi Supply","version":"1.0","type":"link"}
