@Richie C. posted:Not sure where you get your information from, but mine is based upon 20 years experience racing R/C cars across the country and dealing with different kinds of motor, wheel and other ball bearings and their lubrication needs on an almost daily basis.
I never said ball bearings don't require lubrication. If you think you can squeeze some oil into a sealed bearing, then more power to you. In addition, ceramic bearings typically require a different lube than steel ball bearings.
If you knew anything about lubrication, which you clearly do not, you would understand that oils are generally rated by viscosity, which, in layman's terms describes the thickness or stickiness of a fluid (in this case oil). Scientifically, it relates to the resistance of a fluid to flow or the internal friction of a moving fluid. The higher the viscosity number, the thicker the fluid and the more resistance it has.
Ball bearings, especially where moving wheels are concerned such as in train trucks, are meant to move freely without a lot of drag or resistance. I never said you couldn't use gear lube to lubricate a ball bearing. However, gear oil (by definition) is designed to be applied to gears where a more viscous lube is needed as opposed to ball bearings where it is generally more desirable to use a thinner, less viscous oil so the wheels spin more freely and the steel balls don't have as much resistance from a thicker lube, like gear oil.
That's why I recommended a thinner oil, specifically designed for ball bearings rather than a gear lube.
Now exactly where did you get your information from ?

Me,…. I’m sure glad you’ve become an expert playing with RC cars., My experience is 35 years in the automotive industry. Y’all folks sometimes make mountains out of mole hills, ….RC cars don’t make you an expert, I’ve forgotten more about viscosity then you’ll ever know playing with RC cars buddy,…..
