    2021-3-10 · One of the lathe spindle bearings is bad (on the drive side of the spindle). I'm looking to replace it, hopefully with something better than was in there originally; but I don't know where to start, and have some questions: 1. It originally was a ball bearing, 35 mm ID, 72 mm OD. Am I better off replacing it with a roller bearing?
