I'm having a South Bend 16" plain bearing spindle reworked with hard chrome to repair a damaged front journal surface. Two questions to consider:
For reference, the South Bend factory spec on the journal in question is 2.8735" to 2.8740", ground and superfinished to 2-4 microinches.
Thanks,
Tom
- What is the max concentricity deviation between the new journal and the original factory journal that plain bearings should be able to tolerate?
- How far undersized could the new journal be finished and the bearing expanders still take up the slack?
