I am going to ask him about the correct means of greasing the bottom bearings but I thought I'd ask you guys for your thoughts as well.
When I pulled the spindle, there was grease packed everywhere. I've included a section from the drawing of the head below as a reference. As these linear contact bearings don't have seals, I'm guessing the space between the two (the brown space) would be packed with grease, but what about the space above these (blue space) - should grease be packed in here as well?
Do you have a lubrication guide for the machine, something often found in a manual? I've never serviced one at that level, but I think on Bridgeports one of the oil cups feeds those bearing with light spindle oil. I don't know if grease is a good idea.
