This sheave is an AK79 style component, a standard designation in the HVAC and mechanical power transmission industry. Sheaves are critical components in belt-driven HVAC equipment, including air handling units, furnace blowers, rooftop units, and commercial ventilation systems. They work alongside V-belts to transfer rotational power from a motor to a blower or fan assembly, controlling airflow and system performance.\u003c\/p\u003e\u003cp\u003eThe fixed bore design means the sheave has a set 1 inch bore diameter, making it straightforward to mount directly onto a motor or blower shaft of the matching size. Unlike adjustable sheaves, a fixed groove sheave provides consistent, reliable belt alignment and speed ratios. This makes it a preferred choice for replacement applications where the original equipment specification calls for a fixed sheave. HVAC technicians and mechanical contractors rely on fixed sheaves when restoring a system to its factory-designed operating point.\u003c\/p\u003e\u003cp\u003eThe AK79 designation identifies the pitch diameter and groove profile of this sheave, which is compatible with standard A-section V-belts. Proper sheave and belt pairing ensures efficient power transfer, reduces belt wear, and extends the overall service life of the drive system. Using the correct replacement sheave also helps maintain the designed airflow and static pressure for the system, keeping it within equipment specifications and energy efficiency targets.\u003c\/p\u003e\u003cp\u003eThis Source1 2812496000 sheave is a direct replacement part suited for service technicians, HVAC contractors, and facilities maintenance professionals working on belt drive blower systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFixed single groove design for consistent belt alignment and reliable power transfer\u003c\/li\u003e\n\u003cli\u003e1 inch bore diameter for direct shaft mounting on compatible motor or blower shafts\u003c\/li\u003e\n\u003cli\u003eAK79 style, compatible with standard A-section V-belts used in HVAC belt drive applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Source1 2812496000 fixed single groove AK79 sheave with a 1 inch bore is a dependable replacement component for HVAC belt drive systems, delivering consistent performance and straightforward installation for service professionals.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOURCE1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2812496000\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSheave Type\u003c\/strong\u003e: Fixed Single Groove\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle Designation\u003c\/strong\u003e: AK79\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Section Compatibility\u003c\/strong\u003e: A-Section V-Belt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Grooves\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YORK","offers":[{"title":"Default Title","offer_id":51121098850610,"sku":"2812496000","price":182.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304884773.png?v=1778043919","url":"https:\/\/voomisupply.com\/products\/source1-2812496000-fixed-single-groove-sheave-1-inch-bore-ak79","provider":"Voomi Supply","version":"1.0","type":"link"}
