It features a 4.25-inch outside diameter and accepts an H-style QD bushing, allowing bore sizes from 0.375 inches up to 1.5 inches to be accommodated without changing the sheave itself. The sheave is compatible with A-section V-belts at a 3.5-inch pitch diameter and B-section V-belts at a 3.9-inch pitch diameter. At 3.2 pounds, it is a compact, field-serviceable component suited for fan, blower, and pump drive assemblies. Installation and removal are handled by HVAC mechanics, millwrights, and mechanical contractors.\u003c\/p\u003e\u003cp\u003eThis sheave is commonly installed on belt-driven blower assemblies, supply and return fans, cooling tower fan drives, and pump systems found in commercial and light industrial facilities. The QD bushing design allows fast, repeatable shaft mounting and removal without special tooling, making it practical for planned maintenance and emergency replacement work on belt-drive systems where minimal downtime is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-groove design accommodates dual V-belt drive configurations for increased power transfer capacity\u003c\/li\u003e\n\u003cli\u003eH-style QD bushing interface accepts bore diameters from 0.375 inches to 1.5 inches\u003c\/li\u003e\n\u003cli\u003e4.25-inch outside diameter with 3.5-inch A-section belt pitch diameter and 3.9-inch B-section belt pitch diameter\u003c\/li\u003e\n\u003cli\u003eQD bushing mount allows tool-efficient installation and removal, reducing maintenance time on belt-drive assemblies\u003c\/li\u003e\n\u003cli\u003eLightweight at 3.2 pounds, suitable for space-constrained drive housings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with H-style QD bushings and A-section or B-section V-belts.

Disconnect and lock out all power to the drive system before removing or mounting the sheave. Align the sheave parallel to the mating sheave within manufacturer-recommended tolerances before fully tightening the QD bushing fasteners. Check belt tension and sheave alignment after installation and re-inspect after the first few hours of operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Grooves\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch A Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch B Diameter\u003c\/strong\u003e: 3.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Style\u003c\/strong\u003e: H (QD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171804\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1042993\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51538964644146,"sku":"1042993","price":149.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11f0f7a8bbbd49bcf5648f469f1f307d_677267aa-23de-4539-98d5-b6b3baa45732.jpg?v=1785831152","url":"https:\/\/voomisupply.com\/products\/browning-1042993-qd-bushed-v-belt-sheave-2-groove-4-25in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
