The X suffix denotes EXTRA PRECISION. The B-108X is now GB108. I have not had any experience with the BH-812X, but I suspect that a GBH812 is not available. The origials were made by Torrington, and the company is now owned by KOYO. You may not use a B108 to replace a GB108. The B108 has a slightly larger diameter, and when pressed into the bore, it will shrink too small to accomodate the shaft it supports. The GB-108 is for a 5/8" shaft and is 1/2 inch long. The BH812 is for a 1/2" shaft and is 3/4" long. If I can locate my old Torrington catalog, I’ll try to find the specs for your bearings and post them here. R.T.
