I have the 8 inch lortone 4 wheel wet sanding lapidary machine, I need the bearings for the shaft.... I also need the rubber inserts that connect to the machine and go around the shaft... Is this the correct bearing, and do you know where I could get the ...rubber shaft seals

It would be best to take the machine apart to make sure this is the correct bearing. It could be this one or the other bearing that we sell. Lortone has used both. So it is difficult to know which you have. Are you talking about the insulating bushings part number 217-020? If so we can order these for you. We don't stock them.
