The Question is what type of crank and whatcha going to do with it. If it's a cast rank in a stock or mildly hopped up street ride it will be just fine. If its a nitrided steel crank they may have ground through the nitriding. Steel cranks without the nitriding will not wear as well as an iron crank. I should add that if it is already 30 under and need turn again you probably not find bearings for another regrind time to get a new one.
