With a 2.95-inch outer diameter and a 7\/8-inch finished bore, this sheave is ready for installation without additional machining. It accepts standard 4L or A-type V-belts, with a pitch diameter of 2.2 inches and a B-type belt pitch diameter of 2.6 inches. Weighing 1.9 pounds, it fits compact drive assemblies where space and weight are factors. HVAC technicians and mechanical contractors typically install this component on blower and fan assemblies as part of variable or fixed-speed belt-drive systems.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for light-duty to medium-duty belt-drive applications found in residential and commercial HVAC equipment, including air handlers, blower units, and ventilation fans. Its finished bore accepts a 7\/8-inch shaft directly, making it a straightforward drop-in for sheave replacement or new drive assembly builds. The two-groove design allows parallel belt configurations that distribute load across both grooves, which is common in HVAC fan drive setups requiring redundant belt engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-groove design accommodates parallel 4L or A-type V-belt configurations\u003c\/li\u003e\n  \u003cli\u003eFinished bore at 7\/8 inches — no machining required for installation\u003c\/li\u003e\n  \u003cli\u003eCast iron construction provides durability in continuous-duty belt-drive applications\u003c\/li\u003e\n  \u003cli\u003e2.95-inch outer diameter suited for compact drive assemblies\u003c\/li\u003e\n  \u003cli\u003e2.2-inch pitch diameter for 4L or A-type belts; 2.6-inch pitch diameter for B-type belts\u003c\/li\u003e\n  \u003cli\u003eOverall length through bore of 1-31\/32 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-build component for belt-drive systems using standard 4L, A-type, or B-type V-belts on 7\/8-inch shafts in HVAC blower and fan drive assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by HVAC technicians or mechanical contractors experienced in belt-drive systems. Disconnect and lock out all power to the unit before removing or installing any sheave. Ensure the shaft is clean and free of burrs before sliding the sheave into position, and verify belt alignment and tension after installation per the belt manufacturer's specifications. Consult applicable mechanical codes and equipment service manuals for torque and alignment guidance.\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 Sheave\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 2.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 7\/8 inches (finished bore)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (4L or A-Type Belt)\u003c\/strong\u003e: 2.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (B-Type Belt)\u003c\/strong\u003e: 2.6 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: 1.9 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: 1033133\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51540703248690,"sku":"1033133","price":148.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d59897e8985177cfa158192ec18d3421.jpg?v=1785862406","url":"https:\/\/voomisupply.com\/products\/browning-1033133-two-groove-cast-iron-sheave-2-95in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
