How much grease is in a new bearing?
Most new bearings seem to have a minimum of grease and a very light duty grease as well. Keep in mind that the bearing manufacture has no idea where that bearing will end up, so it is my feeling that a middle of the road, low viscosity grease is used. These “stock” greases are “gone” in some instances on our heli’s, in a matter of minutes of running. In other areas they are diluted easily with fuel residues and also cleaning fluids we use on our heli’s. The U76 grease has worked well in all of these instances.
