It features a 1 inch finished bore diameter and a 3.15 inch outside diameter, with a belt pitch diameter of 2.8 inches for B-type belts and 2.4 inches for 4L or A-type belts. The through-bore length measures 1-31\/32 inches. Cast iron construction provides durability under continuous load and resists wear in demanding drive system environments. This sheave is installed by HVAC technicians, millwrights, and mechanical contractors on motor and driven-shaft applications.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial HVAC systems, fans, blowers, and general industrial belt-drive assemblies where a two-groove configuration is required. The finished bore is ready for installation without additional machining, making it a direct-fit solution for retrofit and new construction drive setups. Typical applications include belt-driven air handlers, exhaust fans, and centrifugal blowers where matched dual V-belt arrangements are used to transmit motor power to a driven component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-groove design accepts matched B-section or A-section V-belts\u003c\/li\u003e\n  \u003cli\u003eFinished 1 inch bore is ready for installation without machining\u003c\/li\u003e\n  \u003cli\u003e3.15 inch outside diameter with 2.8 inch pitch diameter for B-type belts\u003c\/li\u003e\n  \u003cli\u003e2.4 inch pitch diameter for 4L or A-type belt applications\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for strength and wear resistance under continuous load\u003c\/li\u003e\n  \u003cli\u003eThrough-bore length of 1-31\/32 inches accommodates standard shaft configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation sheave for belt-drive systems requiring a two-groove, 1 inch bore pulley compatible with B-section or A-section V-belts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician, millwright, or mechanical contractor. De-energize and lock out the motor before removing or installing any sheave. Verify shaft diameter and keyway dimensions before mounting, and ensure set screws or taper-lock hardware are properly torqued per the shaft and hub manufacturer specifications. Check belt tension and sheave alignment 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\u003eSheave Type\u003c\/strong\u003e: Two Groove\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1 inch finished bore\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B-Type)\u003c\/strong\u003e: 2.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (4L or A-Type)\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Through Bore\u003c\/strong\u003e: 1-31\/32 inches\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: 2.05 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: 1033208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51544642486578,"sku":"1033208","price":304.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29caa5f6ddb744b346157b8b43fb2b80_c3102832-1361-4166-9556-b4ed450af4fa.jpg?v=1785932388","url":"https:\/\/voomisupply.com\/products\/browning-1033208-two-groove-cast-iron-sheave-1-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
