Sized at 5\/8 inch wide by 42 inches in length, this is a classical B-section V-belt built for reliable torque transfer in belt-driven equipment. The black rubber construction provides resistance to wear and heat under continuous operation. HVAC technicians, mechanical contractors, and industrial maintenance professionals use B-section belts like this one on fan drives, blower assemblies, compressors, and general-purpose machinery where consistent belt tension and grip are required.\u003c\/p\u003e\u003cp\u003eThe B39 fits standard B-section sheaves and pulleys found across a wide range of residential and commercial HVAC equipment, agricultural machinery, industrial conveyors, and pump drives. It is a direct classical-section replacement in any application calling for a B39 belt. Installations range from rooftop unit blower assemblies to industrial fan decks and belt-driven pump systems. Sold individually, with a package quantity of 30 units available for stocking orders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClassical B-section profile for compatibility with standard B-section sheaves and pulleys\u003c\/li\u003e\n\u003cli\u003e5\/8 inch top width by 42 inch outside circumference sizing\u003c\/li\u003e\n\u003cli\u003eBlack rubber construction for heat and wear resistance in continuous-duty applications\u003c\/li\u003e\n\u003cli\u003eSuitable for HVAC blower drives, compressor drives, pump drives, and general industrial machinery\u003c\/li\u003e\n\u003cli\u003eSold as individual belt; package quantity of 30 available for bulk stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard B-section classical V-belt replacement for any drive system specifying a B39 belt cross-section and length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eB-section V-belts are installed and replaced by HVAC technicians, millwrights, and mechanical maintenance technicians. Always de-energize and lock out the equipment before removing or installing a belt. Proper belt tension is critical — an under-tensioned belt will slip and generate heat, while an over-tensioned belt accelerates bearing wear. Inspect sheave grooves for wear or damage before installing a new belt.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Section\u003c\/strong\u003e: B (Classical)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop Width\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 42 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 30 per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JASON INDUSTRIAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B39\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JASON INDUSTRIAL","offers":[{"title":"Default Title","offer_id":51524656660786,"sku":"B39","price":203.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75a1189514bf011b0b83a91c9cb25e21_49d97967-cd22-4c3f-bf06-e194625b7b7d.jpg?v=1785454297","url":"https:\/\/voomisupply.com\/products\/jason-industrial-b39-rubber-v-belt-5-8x42-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
