Cast from iron for durability under continuous operation, this sheave features a 5\/8 inch finished bore and a 4.95 inch outer diameter. The belt pitch diameter for Type B or A belts measures 4.2 inches, and the overall length through the bore is 1-5\/32 inches. It is installed by HVAC technicians and millwrights in belt-driven fan and blower assemblies where precise pulley sizing affects airflow and equipment efficiency.\u003c\/p\u003e\n\u003cp\u003eThis sheave is suited for residential and light commercial belt-drive applications, including HVAC air handlers, blower assemblies, and general power transmission setups using Type 4L or Type A V-belts.
