Inside Diameter: The distance across the center hole, or bore, of the product. This dimension should match the diameter of your shaft or bolt.

Keyway: The width of the key used to anchor the pulley to a shaft. A negative keyway means this has an integral keyway, so no separate key will be needed to anchor the pulley.

Most shafts have the following standard keyway sizes:

Shaft Size/ Inside Diameter Standard Keyway Size
1/2” (0.50) 1/8” (0.125)
5/8” (0.625) 3/16” (0.187)
3/4” (0.75)
7/8” (0.875)
1” ¼” (0.25)

Material: Describes what the product is made from. Plastic, aluminum, and diecast are softer, lighter, and do not rust. Steel and cast iron are meant for heavy-duty applications, but can rust in certain circumstances.
