Cast from iron, this sheave measures 3.15 inches in outer diameter with a 7\/8 inch finished bore and a 1.75 inch face width. The B-pitch belt diameter is 2.8 inches, and the pitch diameter for 4L or A-type belts is 2.4 inches. The through-bore length is 1-31\/32 inches. Weighing 2.15 pounds, it is a direct drop-in replacement sheave suited for blower and fan drive assemblies in residential and light commercial systems.\u003c\/p\u003e\n\u003cp\u003eThis sheave is commonly installed on belt-drive blower assemblies, fan shafts, and auxiliary drive systems where a two groove configuration is required to run dual V-belts. A finished bore means the bore is machined to a specific diameter and is ready to mount to a shaft without additional boring. Typical applications include air handling units, furnace blowers, and general mechanical drive systems that accept standard A or 4L cross-section V-belts. Installation is performed by HVAC technicians or mechanical tradespeople as part of a blower motor or drive assembly service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo groove configuration supports dual V-belt drive setups\u003c\/li\u003e\n  \u003cli\u003eFinished bore at 7\/8 inch for direct shaft mounting without rework\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability in belt-drive service\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard A and 4L cross-section V-belts\u003c\/li\u003e\n  \u003cli\u003eCompact 3.15 inch OD suitable for space-constrained drive assemblies\u003c\/li\u003e\n  \u003cli\u003eThrough-bore length of 1-31\/32 inches for adequate shaft engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement sheave for belt-drive blower and fan assemblies using standard A or 4L type V-belts with a 7\/8 inch shaft bore requirement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSheave installation is typically performed by a licensed HVAC technician or qualified mechanical tradesperson. Disconnect and lock out all power to the drive system before removing or installing any sheave. Ensure the shaft is clean and free of burrs before seating the bore, and verify set screw torque against the drive assembly manufacturer specifications. Align sheave grooves within the drive system before tensioning belts to manufacturer-recommended deflection values.\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: 3.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 7\/8 inch (finished bore)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eB-Pitch Belt Diameter\u003c\/strong\u003e: 2.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (4L or A Belt)\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough-Bore Length\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: 2.15 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: 1033190\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51539036078386,"sku":"1033190","price":310.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a476933d4e24d1761186aac9391d3c6.jpg?v=1785833397","url":"https:\/\/voomisupply.com\/products\/browning-1033190-two-groove-sheave-3-15in-od-7-8in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
