It accepts 5V, A, and B section belts and features an 8.88-inch outside diameter with belt pitch diameters of 8.7 inches for 5V belts, 8.2 inches for A-section belts, and 8.6 inches for B-section belts. The sheave accepts bore diameters ranging from 0.625 inches up to 2.25 inches through the use of a Type B QD bushing. Cast iron construction provides durability under continuous-duty load. This component is installed by HVAC technicians, millwrights, and mechanical contractors on fan and blower drive assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for commercial and industrial belt-drive applications where multi-groove power transmission is required. Typical installations include rooftop unit supply fans, air handling unit blowers, industrial exhaust fans, and similar rotating equipment. The four-groove configuration allows for higher torque capacity compared to single or dual-groove sheaves. The QD bushing system simplifies installation and removal on the drive shaft without requiring a press or special pullers in most configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFour grooves accommodate 5V, A, and B section V-belts\u003c\/li\u003e\n  \u003cli\u003eQD Type B bushing interface for tool-friendly shaft mounting and removal\u003c\/li\u003e\n  \u003cli\u003eBore range of 0.625 inches to 2.25 inches for broad shaft compatibility\u003c\/li\u003e\n  \u003cli\u003e8.88-inch outside diameter with a 5V pitch diameter of 8.7 inches\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for strength and wear resistance under continuous operation\u003c\/li\u003e\n  \u003cli\u003eIndustry-standard UNSPSC classification 31171804 for procurement compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5V, A, and B section V-belts in four-groove belt-drive configurations.

Disconnect and lock out all electrical power and ensure the drive shaft is at rest before mounting or removing the sheave. The QD bushing should be tightened in accordance with the bushing manufacturer's torque sequence to ensure concentricity and secure shaft engagement. Verify belt tension and sheave alignment with a straightedge or laser alignment tool after installation 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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Belt Sections\u003c\/strong\u003e: 5V, A, B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 8.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (5V)\u003c\/strong\u003e: 8.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (A)\u003c\/strong\u003e: 8.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B)\u003c\/strong\u003e: 8.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Style\u003c\/strong\u003e: Type B QD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 17.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171804\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: 3694593\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51543062217010,"sku":"3694593","price":506.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ceb16639dfd43b4e7540c453ee3177b5.jpg?v=1785914787","url":"https:\/\/voomisupply.com\/products\/browning-3694593-qd-bushed-v-belt-sheave-4-groove-8-88-in","provider":"Voomi Supply","version":"1.0","type":"link"}
