Low temperature lube (-50C)
Low temperature lube (-50C)
(OP)
I'm looking for a low temperature lube for my planetary gearheads that should operate from -50C to 140C. The gearheads are small, from 6mm in diameter to 20mm. Low temperature has been a the main problem.

You could try tungsten disulphide (WS2) coatings. It provides a very low coefficient of friction and works at low temperatures (it was originally developed by NASA for satellite use) - http://www.ws2.co.uk/home.htm for a UK supplier; http://www.brycoat.com/dry-film-ws2.html for s US supplier.
Cheers,

I'd also look at DuPont Krytox greases.

These are Dow Corning Molykote 33 greases. We use them in needle bearings and miniature gears. We have 30 years experince with them. However, our gears doesn't work continuously but may reat for many years and then used again.
Recall that thesea are silicone greases therefore you should avoid any silicone rubber seals.

Thanks for the feedback. Our gearheads are typically mounted to brush commutated PM DC motors. Silicone has an adverse reaction to the commutation system (see attached).
