Machined from cast iron, this sheave features a 1 inch finished bore and an 11.25 inch outer diameter, making it a direct-mount component for blower and fan shaft assemblies. The belt pitch diameter measures 11.4 inches, with a 3\/4 inch groove width suited to standard B-section and A-section V-belts. The overall length through the bore is 1-15\/32 inches. Licensed HVAC technicians, millwrights, and mechanical contractors typically install this type of sheave during blower motor upgrades, belt drive replacements, or system retrofits.\u003c\/p\u003e\n\u003cp\u003eThis sheave is appropriate for use on belt-driven blower assemblies found in residential and light commercial air handling units, rooftop units, and fan coil systems. It accommodates Type B or A V-belts with an 11.0 inch pitch diameter, as well as 3L-section belts at a 10.66 inch pitch diameter. The finished bore eliminates on-site boring, simplifying installation on standard 1 inch motor or blower shafts. Cast iron construction provides the mass and rigidity needed for consistent belt tension and reduced vibration in continuous-duty applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished 1 inch bore — ready to mount on standard motor or blower shafts without additional machining\u003c\/li\u003e\n  \u003cli\u003e11.25 inch outer diameter with 11.4 inch belt pitch diameter for accurate drive ratio calculations\u003c\/li\u003e\n  \u003cli\u003eCompatible with Type B\/A V-belts (11.0 inch pitch diameter) and 3L-section belts (10.66 inch pitch diameter)\u003c\/li\u003e\n  \u003cli\u003eSingle groove design for straightforward single-belt drive configurations\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability and vibration damping in continuous-duty service\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch groove width suits standard B and A section V-belt profiles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade sheave for single V-belt drive systems using B-section, A-section, or 3L-section belts on 1 inch bore shafts.

Disconnect and lock out all electrical power to the equipment before removing the existing sheave or belt. Secure the sheave to the shaft using a properly sized key and set screw, and verify shaft and sheave alignment with a straightedge or laser alignment tool before reinstalling the belt. Confirm belt tension according to the belt manufacturer specifications to prevent premature wear or slippage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSheave Type\u003c\/strong\u003e: Single Groove Sheave\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1 inch (finished)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 11.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter\u003c\/strong\u003e: 11.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter — Type B\/A Belt\u003c\/strong\u003e: 11.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter — Type 3L Belt\u003c\/strong\u003e: 10.66 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Through Bore\u003c\/strong\u003e: 1-15\/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: 5.35 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: 1027523\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51541352644914,"sku":"1027523","price":186.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d90ff21676c2463e67a9dd53a4d1e8ff.jpg?v=1785873279","url":"https:\/\/voomisupply.com\/products\/browning-1027523-single-groove-sheave-1in-bore-11-25in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
