Shaft Adapter Bushing

Bushings come in two sizes,  5/8" to 1/2" - 3/4" long, and 3/4" to 5/8" - 7/8" long. This allows our 8" wheels to be used on grinders with 1/2" and 3/4" shafts. They are all but impossible to find on the internet, and these stainless steel bushings were made especially for us.
