Grease or oil on a scroll chuck rebuild?

Microlubrol M-77 moly grease is a 64% moly grease used for high pressure sliding contact. When the base oil dries up the moly takes over and acts as a dry lube made up of microscopic ball bearings of molybdenum. I get it from Amazon. It is expensive but a little bit goes a long way. The down side is cost and the fact that it is black and can get messy if too much is used. I've read that they recommend it not be used on ball bearings as they tend to slide on the moly and don't rotate, possibly causing flat spots. I have not seen that problem so I can't vouch for it. I first started using on rifle bolt lugs. Super lube says that their product is not for high pressure low speed contact.
