With a 1 inch bore diameter and a 3.35 inch outer diameter, this sheave accommodates standard B-section or A-section V-belts. The cast iron construction provides durability under continuous load and resistance to wear in belt-driven blower and fan applications. A finished bore means no additional machining is required before installation, making it a direct drop-in component for qualified technicians replacing worn or failed sheaves.\u003c\/p\u003e\u003cp\u003eThis sheave is suited for residential and light commercial HVAC blower assemblies, exhaust fans, and general-purpose V-belt drive systems. It accepts 4L or A-type belts with a pitch diameter of 2.6 inches and a B-section belt pitch diameter of 3.0 inches. The bore length through the hub measures 1-31\/32 inches. HVAC technicians and mechanical contractors typically install this component when servicing belt-driven air handlers, furnace blowers, and ventilation equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFinished bore construction eliminates field machining before installation\u003c\/li\u003e\n\u003cli\u003eTwo groove design supports dual V-belt drive configurations for balanced load transfer\u003c\/li\u003e\n\u003cli\u003eCast iron material provides strength and wear resistance in continuous-duty applications\u003c\/li\u003e\n\u003cli\u003eCompatible with standard 4L or A-type and B-section V-belts\u003c\/li\u003e\n\u003cli\u003e1 inch bore diameter with 3.35 inch outer diameter fits common blower shaft sizes\u003c\/li\u003e\n\u003cli\u003eBore length of 1-31\/32 inches provides adequate hub engagement for secure mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement sheave for two-groove V-belt drive systems using 4L, A-type, or B-section belts with a 1 inch shaft bore requirement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all electrical power to the unit before removing or installing any belt-drive components. Ensure the sheave is properly aligned with the mating sheave using a straightedge or laser alignment tool before tensioning belts. Verify set screw torque and belt tension per the equipment manufacturer's service documentation before returning the system to operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSheave Type\u003c\/strong\u003e: Two Groove\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter (OD)\u003c\/strong\u003e: 3.35 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (4L or A-type)\u003c\/strong\u003e: 2.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B-section)\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Length Through Hub\u003c\/strong\u003e: 1-31\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.35 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: 1033265\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542811705650,"sku":"1033265","price":337.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a640d7ae536d038242e22f08e4516fc5.jpg?v=1785908092","url":"https:\/\/voomisupply.com\/products\/browning-1033265-two-groove-cast-iron-sheave-1in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
