I hate to show my ignorance, but I honestly didn’t know that there was anything but ball bearings. I got it on eBay – here’s the description.
“The chrome is very nice and looks to be unworn and well cared for. The headstock has bronze or brass bearings that show no wear of scratches. I oiled and adjusted them and installed a new belt. The tail stock is, as you can see a collet holding and the fit of the sliding collet holder is still snug showing little or no use. The tool holder has turned darker with age but is made by Levin and I beleive is original to the lathe. This has been together all its life and not made up of assorted parts. Great head and tailstock alignment. Bed shows little or no wear…”
Perhaps you can deduce that from the above. Is there a problem with one type over the other?
