I finally received my ballscrews and ballnuts. Now, I'm at the point of planning on a good thrust bearing arrangement. I'm working with a micro mill (Harbor Freight), and I'm trying to replace all of the cheap assemblies with something that I can count on.
Now to the question: What kind of thrust bearing arrangement is suited to such a small mill? I know I need radial and axial support from the bearings. Can anyone recommend a cheap (read: inexpensive but functional) bearing arrangement? Pictures are good, too
Would opposing timken (sp?) bearings work, or do I need to go with the $20/each bearings that dually support axial and radial loads?
Thanks,
Billy Byler
