I am familiar with Thomson TWN 16 which fit around 1" shaft and they do not have any slop. I also have undersize shaft with slop in it but I am afraid to use it for same reasons that you have. The shaft is hardened. It brought another question in my mind, how do I know when the bearings are worn? and the only answer that I can come up with is if there is too much slop. But your bearings are linear and maybe I am mixing apples and oranges, it would'nt be the first time. |
