Concerning Nachi Sealed Bearings:

One of the most common misconceptions that cause a high number of bearing failures is that a bearing needs to be completely packed full. Many people have been taught; the more grease, the better. We have even heard of cases where people do not feel bearing manufacturers use enough grease in sealed and shielded ball bearings, so they remove one seal or shield and pack the bearing with more grease. These misconceptions are completely false. Over lubri-cating the bearings forces the motor to work harder.

Nachi standard grease fill for sealed and shielded ball bearings is 20% to 30% full

Too much grease can cause excess friction, thereby overheating the bearing and causing remature failure.

Only a small of grease is required to lubricate a bearing in motion.

When a bearing is in motion, most of the grease is pushed to the side (channeling) leaving a thin film of oil between the raceways and rolling elements.

When using open bearings, pack the bearing as follows:
