How much drag is added to a greased bearing?
Any grease added to a bearing will increase the drag slightly. The U 76 did not create what I felt was excessive drag on the bearing either. Note that the bearings will feel a little draggy compared to a new bearing, but “The Greaser” greased bearing will expel excess grease to its own “operating equilibrium” for the condition it is used under. In other words a bearing in a clutch support block turning at 10,000 rpm, will expel more grease than a main shaft bearing turning at 1700 rpm. A bearing with no grease will have very low resistance….for a while 🙂 same for an oiled bearing. A greased bearing that has grease that stays in it, at an adequate amount, will out perform an improperly lubed bearing, both in longevity an smoothness.
