Default WD40 on bearings anybody

Bearings

what would WD40 do to a set of bearings? I was just wondering about that since motor spray and oils don't do any damage. The WD40 would be used on Losi Metal Shielded bearings with their shields off on each side and it would just be put in and then run


Keep on,
Brandon

WD 40 is more of a silvent than a lubricant. I would just use some motor spray to clean them out and then add a drop or two of some good air tool oil such as marvels.

When I used to Mountain bike we used a teflon based liquid as a chain lube, from Finish Line. Its very light viscosity and drys into a wax that doesnt attract dirt (at least not as much).

Anyways thats what I use.....Tri-Flo works good too (anouther teflon impregnated lube, but doesent have the same "dry" effect

wd40 will not harm your bearings. I know serveral people that clean bearings out with brake cleaner then let them soak in wd40 and install in the car.

I actaully soak my bearings in WD-40 overnight when I rebuild my cars. I put them in one of those metal Altoid's cans & fill it with WD-40, give it a shake & let it sit overnight. I do this with most of my metal parts. It seems to work very well.

Default wd40

WD40 is a penetrant not a lubricant. Your drivetrain will spin free but it will not due much for life of bearings.

I use bicycle chain lube as it is readily available and you can buy about 100x the same amount for 3$ than you can in the hobby shop...you can fill your micro oiler and 10 of your friends also!!

Try Pedros Extra dry chain lube or Triflow. Triflow is a little thicker and you lose a little free spin but it does not have to be applied as often.

If you can find it Progold chain lube works very well but not many cycling shops carry it.

I think that the Microlon product and the Finish Line product are one and the same....I think Finish Line may even just be repackaged Microlon....as I recall reading something like that on the package

I use FinishLine on my gears but air tool oil on bearings. The problem with a spherical ball in a metal race is that the closer you get to the axis of rotation of the ball, the slower it is traveling in the race. This means that part of the metal is sliding. You need something with some high anti-scuffing properties in there to prevent premature wear of the metal. Air tool oil has been formulated to have these anti-scuffing properties. My .02.

I'm not how thick the tooling oil is but you want to use a good thin oil.
