Lubrication of lathe chucks

[DaedalusParticipant @daedalus]

Hi all, there was a thread about lubrication of lathe chucks with quite a bit of discussion as how to do it and what "grease" to use. I can no longer find the thread or I would have posted on that one.

I was looking for some new jaws for my Pratt Burnerd chuck and came across this Pratt grease specially for chucks.

I couldn't find any jaws but thought the link might be of use to others.

Cheers,

I've got a tube of this which I claimed as part of my redundancy package! we used it on the chucks used in very heavy continuous production. It is very expensive and always looked just like the ordinary Moly grease we used for years before someone decided to buy this. Can't say that I noticed any great difference in wear levels on the scroll or jaws after we made the change, and it does still get washed away by coolant. Always impressed how long the chucks lasted and retained reasonable accuracy given the hard life and occasional abuse they sustained. I do use it as it's there but don't think I need to re grease every few months in the home workshop!

Should point out that not all were used on lathes, the ones that really suffered from coolant washout were on indexing tables on the mills and therefore were mounted horizontally.
