0.5625 KEYED H-BUSHING item number: 1-2913-56 Is it correct to assume this has a 3/16" keyway?
A: No. This 9/16" bushing is keyed for 1/8" keystock.

New to this stuff. I am trying to get a 3.5" OD pulley on a .617" x .3/4"L x .649 taped shaft with 18/"w x 1/16"H key. How do you know what size the busing should be? Split the difference between the ends of the shaft or use the largest end of the shaft?
A: Tapered shaft sizes are called out by the large end, with the taper angle being specified. If you have a tapered shaft, these hubs will not work well. These are bored for smooth straight keyed shafts, with 'taper' referring to how they mate with the pulleys.
