Manufactured from cast iron, this sheave features a 1-1\/8 inch finished bore and a 4-3\/4 inch outside diameter, with a belt pitch B diameter of 4.4 inches and a pitch diameter of 4.0 inches for 4L or A type belts. The through-bore length measures 1-15\/32 inches. Weighing 4.25 pounds, it is built for the load demands of HVAC blower assemblies, industrial fan drives, and similar belt-driven equipment. Licensed HVAC technicians and mechanical contractors handle this type of sheave replacement as part of air handler and rooftop unit drivetrain service.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial belt drive applications where two-groove V-belt configurations are required. Typical installations include air handler blower sections, ventilation fan drives, and commercial HVAC units using B-section or A-section V-belts. The finished bore accepts a 1-1\/8 inch shaft directly, eliminating the need for additional boring before installation. The two-groove design allows dual-belt drive setups that distribute load across both belts for improved power transmission and belt life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFinished bore at 1-1\/8 inches fits shaft directly without additional machining\u003c\/li\u003e\n  \u003cli\u003eTwo groove configuration supports dual V-belt drive setups\u003c\/li\u003e\n  \u003cli\u003e4-3\/4 inch outside diameter with 4.0 inch pitch diameter for 4L or A type belts\u003c\/li\u003e\n  \u003cli\u003eCast iron construction provides durability in continuous-duty blower and fan applications\u003c\/li\u003e\n  \u003cli\u003eThrough-bore length of 1-15\/32 inches for secure shaft engagement\u003c\/li\u003e\n  \u003cli\u003eWeighs 4.25 pounds for straightforward handling during installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement sheave for belt drive systems using B-section or 4L\/A-section V-belts with a 1-1\/8 inch shaft bore requirement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or mechanical contractor.
