Lubricating a large bearing - GIF

[Frank S]

Not sure that is lubricating as much as applying preservative prior to wrapping in protective plastic....

I imagine you are probably right, Think of how that fine machined bearing race and rollers would look if packaged with nothing on it but manufactured where the humidity is always so high you almost need gills to breathe. the moisture trapped inside the plastic wrapping would tune it brown before it could be delivered.
