Cast iron construction provides rigidity and resistance to wear under continuous belt loading. The sheave features a 1-1\/8 inch finished bore diameter and a 2.95 inch outer diameter, with a belt pitch diameter of 2.6 inches for B-section or A-section belts. The pitch diameter for 4L or A-type belts is 2.2 inches. Overall length through the bore measures 1-31\/32 inches. This part is installed by HVAC technicians and mechanical contractors during blower assembly, fan drive, or belt-drive equipment service.\u003c\/p\u003e\n\u003cp\u003eFinished bore two groove sheaves like the BROWNING 1033158 are commonly used in residential and light commercial HVAC blower assemblies, exhaust fans, and belt-driven equipment where dual V-belt configurations are required. The finished bore accepts standard 1-1\/8 inch shafting without additional machining, making field installation straightforward. Compatible with B-section and A-section V-belts as well as 4L belt profiles, this sheave fits a wide range of OEM and replacement belt-drive configurations found across heating, ventilation, and air conditioning equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore design accepts 1-1\/8 inch shaft diameter with no additional machining required\u003c\/li\u003e\n  \u003cli\u003eTwo groove configuration supports dual V-belt drive arrangements\u003c\/li\u003e\n  \u003cli\u003eCompatible with B-section, A-section, and 4L belt profiles\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability under continuous belt tension and load cycling\u003c\/li\u003e\n  \u003cli\u003eBelt pitch diameter of 2.6 inches suits standard blower and fan drive ratios\u003c\/li\u003e\n  \u003cli\u003eCompact overall bore length of 1-31\/32 inches fits 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 or direct-fit sheave for belt-drive systems using B-section, A-section, or 4L V-belts with a 1-1\/8 inch shaft bore requirement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or millwrights. Disconnect and lock out all electrical power to the equipment before removing or installing any belt-drive components. Ensure the shaft is clean and free of burrs before seating the sheave, and verify set screw engagement against the shaft keyway per standard mechanical practice. After installation, check belt tension and alignment before returning the unit to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 2.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Pitch Diameter (B\/A Section)\u003c\/strong\u003e: 2.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter (4L or A Belt)\u003c\/strong\u003e: 2.2 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\u003eNumber of Grooves\u003c\/strong\u003e: 2\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: 1.65 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: 1033158\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51539002655026,"sku":"1033158","price":148.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f65f02c8b2b4ab0b6cd5bc5733e915d6.jpg?v=1785832466","url":"https:\/\/voomisupply.com\/products\/browning-1033158-two-groove-sheave-1-1-8-in-bore-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
