It features a 3\/4 inch bore diameter and a 2.95 inch outer diameter, with a cast iron construction that provides durability under continuous load. The groove is machined to accommodate 4L or A-type V-belts, with a pitch diameter of 2.2 inches. The overall length through the bore measures 1-1\/16 inches. This sheave is installed by HVAC technicians, millwrights, and mechanical contractors as part of belt-driven blower or fan assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial belt drive systems where a compact, single groove pulley is required. It is commonly installed on blower motor shafts in air handling units, furnaces, and ventilation equipment. The finished bore is machined to final tolerance, accepting a 3\/4 inch shaft without additional boring. The 13\/16 inch face width accommodates standard A or 4L V-belts used in typical HVAC blower drive configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 3\/4 inch — ready to install on standard motor or blower shafts without additional machining\u003c\/li\u003e\n  \u003cli\u003eSingle groove design accepts A-type or 4L V-belts\u003c\/li\u003e\n  \u003cli\u003e2.2 inch pitch diameter for accurate belt speed ratio calculations\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for wear resistance and dimensional stability under load\u003c\/li\u003e\n  \u003cli\u003e13\/16 inch face width suits standard V-belt widths\u003c\/li\u003e\n  \u003cli\u003eCompact 2.95 inch OD fits tight drive configurations in air handler and blower 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-driven blower and fan applications using A-type or 4L V-belts with a 3\/4 inch shaft bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or millwright.
