Trying to rebuild a spindle for an old toolpost grinder and I don’t know how to set up the preload on the bearings. They are SKF 6202 2ZJEM shielded ball bearings for a 15mm shaft and a 35 mm bore. The bearings fit in each end of a tube about 8 inches long. I will turn shoulders on the new shaft for the inner races to stop against. For simplicity I’d like to use Belleville disk springs to take out the end play. McMaster’s sells them specifically for this bearing. Any information would be appreciated.
