The sheave measures 11.28 inches in outside diameter with a belt pitch diameter of 11.1 inches for 5V belts. It accepts bore diameters from 5\/8 inch to 2-1\/4 inches using a B-style QD bushing, which is sold separately. Cast iron construction provides the mass and rigidity required for reliable power transmission in HVAC, industrial fan, and blower drive applications. Licensed HVAC technicians and mechanical contractors typically install this component as part of a belt-drive blower or fan assembly.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial HVAC air-handling units, cooling tower fans, industrial blowers, and other rotating equipment that uses multi-groove V-belt drives. The three-groove configuration allows for higher torque transmission compared to single-groove designs, making it appropriate for larger fan systems where load must be distributed across multiple belts. Compatible belt trade sizes include 5V, A, and B section belts. No specific model or unit compatibility beyond belt cross-section was provided in the product data.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree grooves accommodate 5V, A, and B cross-section V-belts\u003c\/li\u003e\n  \u003cli\u003e11.28 inch outside diameter with 11.1 inch belt pitch diameter for 5V belts\u003c\/li\u003e\n  \u003cli\u003eBore range from 5\/8 inch to 2-1\/4 inch via B-style QD bushing\u003c\/li\u003e\n  \u003cli\u003eQuick Detachable bushing mount allows straightforward removal and reinstallation without specialty pullers\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability and balanced mass in continuous-duty drive applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5V, A, and B cross-section V-belts.

Disconnect and lock out all electrical power to the drive system before removing or installing any sheave. The QD bushing must be properly torqued to the manufacturer bushing specification using a calibrated torque wrench before returning the drive to service. After installation, verify belt tension and sheave alignment with a straightedge or laser alignment tool before start-up to prevent premature belt and bearing wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Grooves\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Belt Trade Sizes\u003c\/strong\u003e: 5V, A, B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 11.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (5V)\u003c\/strong\u003e: 11.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (A)\u003c\/strong\u003e: 10.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B)\u003c\/strong\u003e: 11.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Style\u003c\/strong\u003e: B (QD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 19.15 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: BROWNING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3694346\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51541956133170,"sku":"3694346","price":506.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64b3aeb579630264d9dbad8f0bfd1e89.jpg?v=1785888425","url":"https:\/\/voomisupply.com\/products\/browning-3694346-3-groove-qd-bushed-v-belt-sheave-11-28-in","provider":"Voomi Supply","version":"1.0","type":"link"}
