Cast from iron, it accepts a 7\/8-inch (0.875 inches) bore shaft and measures 4.95 inches in outer diameter with a groove width of 0.75 inches. The belt pitch diameter is 5.1 inches, with compatibility for Type A or 4L belts at a 4.7-inch pitch diameter and Type 3L belts at a 4.36-inch pitch diameter. The overall length through bore is approximately 1-5\/32 inches. This sheave is installed by HVAC technicians, industrial mechanics, and maintenance professionals working on fan, blower, and motor drive assemblies.\u003c\/p\u003e\n\u003cp\u003eThis single groove sheave is suited for residential and light commercial HVAC blower assemblies, exhaust fans, and general-purpose motor-to-shaft belt drive applications. The finished bore means the shaft opening is already machined to final dimension, eliminating the need for additional boring. It is a direct-mount component that pairs with a standard V-belt to transfer rotational power between a motor shaft and a driven component such as a blower wheel or fan.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 0.875 inches — ready to install without additional machining\u003c\/li\u003e\n  \u003cli\u003e4.95-inch outer diameter with a 5.1-inch belt pitch diameter\u003c\/li\u003e\n  \u003cli\u003eCompatible with Type A, 4L, and 3L V-belts\u003c\/li\u003e\n  \u003cli\u003eSingle groove design for straightforward single-belt drive configurations\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability in continuous-duty drive applications\u003c\/li\u003e\n  \u003cli\u003eCompact 0.75-inch groove width suits space-constrained drive assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement single groove sheave for belt-drive systems requiring a 0.875-inch finished bore and a 4.95-inch OD pulley accepting Type A, 4L, or 3L V-belts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a qualified HVAC technician or industrial mechanic. De-energize and lock out the motor at the disconnect before removing or installing any sheave or belt. Verify shaft diameter matches the 0.875-inch finished bore before mounting, and confirm belt type and pitch diameter match the drive system specifications. A properly tensioned belt reduces bearing wear and prolongs sheave life — refer to belt manufacturer tension guidelines for the belt type in use.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.875 inches (7\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter (OD)\u003c\/strong\u003e: 4.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter\u003c\/strong\u003e: 5.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (Type A or 4L Belt)\u003c\/strong\u003e: 4.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (Type 3L Belt)\u003c\/strong\u003e: 4.36 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: 1-5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Finished Bore\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.95 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: 1026673\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51543394976050,"sku":"1026673","price":140.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0b1b89ebdd6434b0947c9cd1614d0e5.jpg?v=1785917835","url":"https:\/\/voomisupply.com\/products\/browning-1026673-single-groove-sheave-0-875-bore-4-95-od","provider":"Voomi Supply","version":"1.0","type":"link"}
