Carrying the manufacturer designation 2TB48, this cast iron sheave features a 5.15-inch outside diameter and accepts bore sizes from 1\/2 inch to 1-3\/4 inch through a P1-style QD bushing. It is compatible with A, B, and 5V belt trade sizes, making it a versatile choice for blower and fan drive assemblies. Licensed HVAC and mechanical contractors install this type of sheave when setting up or adjusting belt-drive systems on air handlers, fans, and similar rotating equipment.\u003c\/p\u003e\u003cp\u003eThis sheave is suited for residential and light commercial HVAC systems as well as general industrial machinery where adjustable or fixed-speed belt drives are used.
