CONCERNING NACHI SEALED BEARINGS:

One of the most common misconceptions that causes 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. 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 When using open bearings, pack the bearing as follows: When the shaft speed is 50% or less of the bearings cataloged limiting speed: pack 1/2 to 2/3 full When the shaft speed is 50% or more of the bearings cataloged limiting speed: pack 1/3 to 1/2 full
