yea it says it all ;D
Some lube info. Any type of lube on a completely clean spinning bearing will just slightly slow down the bearing. And too much thin lube can really slow it down - so you only want 1-2 small drops when you do use any of it. Bearings will eventually spin completely smooth again once the lube is broken with play. Adding thin lube is actually a good thing as it will increase the overall life span of the bearing - it just needs to be broken in again after being applied. So keep that in mind.
Yes, you can lube most stainless steel/steel bearings.
