Analog_sa, sorry to hear about you're bearing problem. I have had no problem with my bearing, but your report is making me wonder about this table. I am surprised Gunther will even answer your email. Keep us informed of the progress, or lack of progress, of you're bearing. Maybe, it will run in, but sounds fishy, at least to me. Maybe someone here, with more knowledge, can help with the problem.
My spindle is OK. so maybe yours is defective.
Which table do you own, and how old is it?
