Cast from iron for durability, this sheave features a 0.5 inch bore diameter and a 3.45 inch outside diameter. The single groove accepts standard B, 4L, or A section belts with a pitch diameter of 3.2 inches, or 3L section belts with a pitch diameter of 2.86 inches. The overall length through the bore is 15\/16 inch and the groove width is 21\/32 inch.
