These bearings are ideal for 1 3/8" diameter. The 5/8" ID is slightly small on 3 of the 4 shafts. The cheap ones they replaced will fit them, but with a bit of filing they will fit. I'd rather get those good bearings to fit than use the cheap ones and not work with them. The good news is that next time they will fit perfectly.
