Cogged belts feature transverse notches on the inner surface that reduce bending resistance, improve flexibility around smaller sheaves, and run cooler than standard wrapped belts. The raw edge construction exposes the cord and rubber compound directly to the sheave groove, increasing grip and power transmission efficiency. HVAC technicians and mechanical contractors install this belt as a direct replacement in blower and fan drive assemblies.\u003c\/p\u003e\u003cp\u003eThe AX48 designation follows industry-standard belt sizing: the AX cross-section measures approximately 0.5 inches wide at the top and the 48 indicates an outside circumference in the nominal 48-inch range. This belt is suited for residential and light commercial air handler blowers, condenser fan drives, and exhaust fan assemblies where a standard A-section cogged replacement is required. It is also used in some refrigeration unit evaporator fan drives and general-purpose mechanical drive systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCogged inner surface reduces bending resistance and heat buildup during operation\u003c\/li\u003e\n\u003cli\u003eRaw edge construction increases sheave contact and power transmission efficiency\u003c\/li\u003e\n\u003cli\u003eAX-series cross-section compatible with standard A-section sheave grooves\u003c\/li\u003e\n\u003cli\u003eSuitable for HVAC blower, condenser fan, and exhaust fan drive applications\u003c\/li\u003e\n\u003cli\u003eIndustry-standard AX48 sizing for straightforward replacement sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for equipment requiring an AX48 cogged V-belt in standard A-section sheave configurations, including residential and light commercial HVAC blower and fan drive assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eBelt replacement should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all power to the unit before opening any drive compartment. Never pry a belt over sheave flanges using tools that could damage the cord pack; loosen the motor mounting to relieve tension before removal and reinstallation. After installing the new belt, adjust tension according to the equipment manufacturer's deflection specification and re-check tension after the first few hours of operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Type\u003c\/strong\u003e: Cogged Raw Edge V-Belt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Series\u003c\/strong\u003e: AX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: AX48\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MARS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: M94578\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MARS","offers":[{"title":"Default Title","offer_id":67664467788082,"sku":"M94578","price":15.6,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/mars-m94578-ax48-cogged-raw-edge-v-belt","provider":"Voomi Supply","version":"1.0","type":"link"}
