CENTRAL ILLINIOS | That is something I have been wondering about for a while so I looked it up on the Drives website. It looks like 60 and 60H are the same except the thickness of the side "link plate" they call it. 60 plate is 0.094 inches and 60H is 0.125. Other than that they are the same size pins and rollers and have the same tensile strength.

So that brings up the question of why pay extra for the 60H if it is not stronger. | |
