Lubrication Advise

[Dan, U.S. Air Force, retired]

I'm playing with a mechanism that involves a piece of nylon rod rotating
inside an aluminum tube. Is lubrication required and if so what kind?

At what RPM. and what kind of loads will be on it?

Actually it will be cycling over an arc of 15º - 20º lateral loads won't
exceed 20 pounds total over a 4 inch length. Longitudinal load is
essentially zero. Cyclic rate won't exceed 5 cycles per second.

Make sure the Aluminum is very smooth. I wouldn't lubricate it at all. I
think you'll find the nylon lives longer than the aluminum that it rides on.

Nylon is self lubricating. It might actually perform worse with grease.
