Re: metal/plastic lead screw lube

Brian,

Krytox. Dupont product. Expensive. But worth it, IMO. Pure Teflon.
Well actually, it's PerFlouroPolyEther (PFPE, an "oil"), thicked into
grease with PFTE (teflon).

Sold in bike shops as Dupont Teflon Bearing Grease. 9 bucks for 18
grams...

This product (Krytox) was originally developed for the space shuttle
turbine pumps. High pressure, high temp, inert requirement.

Hope this helps,

Ballendo

P.S. BSA (Ballscrews.com) sells a grease developed specifically for
their leadscrews/ballscrews. As a second choice, it's a good one.

And white lithium grease is traditional.
