Got it. Ceramic balls. Smoother and rounder then steel. A piece of grit will fvck them up. On the PAP units. Depending on rpm. Used either babbit plain bearings for high rpm, or steel ball bearings for low rpms. High rpms was over 50,000. A lot of it was over 100,000 rpms. all of it was pressure fed oil. The seals were ceramic. Could use your bare fingers touch them. The acid in you skin oil would damage the seals. Had to wear white cloth gloves and wipe the seals down with lens wipes.
