View Full Version : Appropriate bearing Lube?

And the saga continues: The "clean and discover" of my wide belt 14 x 40" Am. Tool Works lathe has provided clues. A date 1-17-23 stamped on the flat tool surace of the headstock, removed upwards of 3/16" of yecch all over (parts cleaner solvent best, spray engine degreaser good at times) revealing gleaming steel and bronze where all was matte black before. 20 plus small brass twist-cap oilers. Several brass oil cups (one missing, replaced with bolt!?!) and a bunch of srews with 'OIL' stamped into the parent stock on pulleys, shafts, cross slide, etc. Can anyone point me at the correct weight oil/oils? how often? How much?Can a gent find the old type oil cups to replace with? Would regular Way Oil do the job? Any input would be appreciated.
Da Nut!

I'd got with lightweight spindle oil for the headstock bearings, as per South Bend. For the pulley shafts, etc., probably about #30 machine oil woul do. Medium-weight way lube for the ways.

Oil all the oil points, a couple of drops, every time you use the lathe.

MSC sells oil cups...dunno if they're the "old type" you're looking for. If need be, make 'em! You got a lathe.... ;-)

Make sure you do not use any hypoid gear oil in the yellow metal bearings or you will be replacing them. Use a R&O Gear & Bearing oil - an ISO 68 is a 20W, ISO 30 about a 10W, iso 100 about 40W. (ISO is the stanadard industry viscosity specification method used). If you cannot find R&O lube then you can sub Anti-wear Hydraulic Fluid, but try for the R&O for the best performance.

The way oil should be an ISO 68 unless you have ball screws then you may require a higher or lower viscosity - normally lower for the ball screws and the linear bearing packs.
