Proper lubrication is essential for adequate bearing life! A bearing cannot survive without it.
AMI Standard Lubricants:
AMI Bearings have an initial fill of lubricant when we manufacture them, therefore it is not necessary to lubricate prior to their initial operation. Below is a list of our standard lubricants and their basic physical properties.

Compatibility:
Beware of Mixing Greases!
When two incompatible greases are mixed, either one of two things can happen. Either the mixture hardens and will not release any of the oil or the opposite effect; the mixture softens and releases all of the oil.
In either case, the end result is basically the same; there is no means to effectively lubricate the bearing. Two good greases, when mixed together can make one very bad grease!
It is recommended to use the same type of grease that was originally supplied with the bearing. When changes in grease type are necessary, please consult your lubricant supplier or AMI engineering staff to determine the compatibility of the mixture
