Cast from iron for durability under continuous load, this sheave features a 3.95 inch outer diameter and a 5\/8 inch finished bore ready for direct shaft installation. The groove width is 3\/4 inch. With a belt pitch diameter of 4.1 inches for Type B or A belts, and 3.36 inches for Type 3L belts, the 1026418 is suited for applications where precise drive ratios and belt alignment are critical to system performance.\u003c\/p\u003e\u003cp\u003eThis sheave is typically installed on motor or driven-shaft assemblies in residential and light commercial HVAC systems, including air handlers, furnace blowers, and ventilation fans. It is also used in general industrial V-belt drive configurations where a compact single groove iron sheave is required. The finished bore eliminates additional machining, allowing direct mounting onto a standard 5\/8 inch shaft.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFinished 5\/8 inch bore — no additional machining required for standard shaft fitment\u003c\/li\u003e\n\u003cli\u003e3.95 inch outer diameter with 4.1 inch belt pitch diameter for Type B and A belts\u003c\/li\u003e\n\u003cli\u003eCompatible with Type 3L belts at 3.36 inch pitch diameter\u003c\/li\u003e\n\u003cli\u003e3\/4 inch groove width for proper belt seating and alignment\u003c\/li\u003e\n\u003cli\u003eCast iron construction for durability and resistance to wear under continuous belt load\u003c\/li\u003e\n\u003cli\u003eOverall length through bore of 1-5\/32 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement single groove sheave for V-belt drive assemblies using Type B, A, or 3L belts on 5\/8 inch shafts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC technician or mechanical tradesperson. Shut down and lock out the equipment per LOTO procedures before removing the existing sheave or belt. Ensure the shaft diameter matches the 5\/8 inch finished bore before installation, and verify belt alignment with a straightedge across both sheave faces after mounting. Proper belt tension should be set per the belt manufacturer specifications before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (Type B or A)\u003c\/strong\u003e: 4.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (Type 3L)\u003c\/strong\u003e: 3.36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 3\/4 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\u003eWeight\u003c\/strong\u003e: 1.6 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: 1026418\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542252618034,"sku":"1026418","price":96.45,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f62980db8dfdabcfc53131a4636b6c9.jpg?v=1785896438","url":"https:\/\/voomisupply.com\/products\/browning-1026418-single-groove-sheave-3-95in-od-5-8in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
