Shaft Size (Bore ID)
SHAFT SIZE
“Shaft size” is the measurement of shaft for your application. It can also be similar to the measurement of the “Bore” or “Inside Diameter” of your bearing. A slightly loose shaft fit is desirable for most applications.
For linkages and rod ends, shafts are not typically used but it refers to the measurement of the bore ID whether you are using a bolt or screw through the inside diameter of your rod end. See image below.
