Constructed from cast iron, this sheave features a 2-inch outer diameter and a 5\/8-inch finished bore, ready to mount without additional machining. The groove width measures 21\/32 inches, and the overall bore length is 15\/16 inches. The sheave weighs 0.4 pounds, making it suited for compact drive assemblies where space and weight constraints matter. Licensed HVAC technicians, millwrights, and mechanical contractors install this type of sheave in blower and fan drive systems across residential and light commercial equipment.\u003c\/p\u003e\n\u003cp\u003eThis sheave is commonly used in belt-driven blower assemblies, fan drives, and small power transmission applications. It accepts 3L, 4L, and A-series V-belts, with a pitch diameter of 1.8 inches for 4L and A-type belts and a pitch diameter of 1.46 inches for 3L-type belts. Its compact 2-inch OD makes it appropriate for tight drive configurations found in air handlers, unit ventilators, and similar equipment where a small-diameter, single-groove pulley is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 5\/8 inches — no additional machining required for standard shaft fitment\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for durability in continuous belt-drive service\u003c\/li\u003e\n  \u003cli\u003eCompatible with 3L, 4L, and A-series V-belts\u003c\/li\u003e\n  \u003cli\u003ePitch diameter of 1.8 inches for 4L and A-type belts; 1.46 inches for 3L belts\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.4 pounds, suitable for compact drive assemblies\u003c\/li\u003e\n  \u003cli\u003eSingle groove design simplifies drive configuration and belt replacement\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 V-belt drive systems using 3L, 4L, or A-series belts with a 5\/8-inch shaft bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or qualified mechanical contractor. Disconnect and lock out all power to the equipment before removing or installing sheaves.
