Can you over grease wheel bearings?
Too much grease volume (overgreasing) in a bearing cavity will cause the rotating bearing elements to begin churning the grease, pushing it out of the way, resulting in energy loss and rising temperatures.

Using the chart and the formula, the bearing only needs
8 grams of grease every 10,000 hours
