What's stopping me from running bearings with just a dusting of PTFE powder instead of grease? Just been thinking about it after experimenting with chain waxing, and having a big bag of PTFE kicking around. If lubrication is about stopping metal on metal contact, and I'm not running the bearing in a situation that needs water keeping out (bearing has a shield anyway) then wouldn't a low friction powder work quite well? Someone with more engineering experience than myself, enlighten me.
