Just wanted to share this with you, Koyo facts about bearing maintenance(lubrication) from the Japanese bearing manufacturer Koyo.

NB. Koyo IAR bearings are used in fishing reels.

Found another table from a manufacturer of aluminum complex grease. I think Yamaha grease is also aluminum complex, so this table seems to confirm
the good properties Alan has been talking about.

interesting.  so when they talk about fluorine compounds or fluorinated oils, are they talking about teflon?

I am not sure, but I think so.  At least name and temperature span point in that direction.

i was curious about bentone.  looks like it's similar to bentonite, which is a clay.

BENTONE SD-2 rheological additive is an
organic derivative of a bentonite clay. It is
designed for use in moderate to high polarity
systems containing solvents such a ketones,
esters, glycol ethers and alcohols, including polar
systems with some aromatic solvents.

Found some synthetic greases containing Bentone, seems as they can resist higher temperatures than other types of grease.  Maybe they use Bentone  because it is cheaper than Teflon?

This one might be work for drags?

http://www.schaefferoil.com/greases.html

The whole product line

Ultra Red, probably a god all purpose grease for reels.
