Hi everyone...

I have a 3 axis CNC Brigeport clone (Ultima 3VK) that I recently purchased used.

I noticed that there is a fair amount of play in the right sealed bearing assembly (on the x axis) that supports the end of the ball screw. When I push and pull on the crank handle I get about 1/16" play back and forth.

I have a couple of questions...


1-Should I consider replacing it? I assume if I keep running it, something worst may fail.

2-Is it a straight forward job? It looks very easy to get to, assuming I don't have to dismantle the table. I assume its press fit, but I have access to a good machine shop and I'm sure they could help.

3-Any ideas on where to look for a replacement?


Thanks for your help,


Carlo
