Like oil analysis, grease sampling and analysis can provide some great information. For high risk equipment it may be appropriate to consider adding a grease analysis strategy to your program. Some of the key ways the analysis could be used:
1.) Root-cause or failure analysis - as noted in previous posts, most bearing failures are not due to bearings wearing out, but rather a failure of the lubrication and most bearings are grease lubricated and this would be a great tool to look for water content, external contaminates, or break down materials.
2.) Lubrication Consolidation - not all greases are compatible and sampling grease on a new machine, or unknown machines could be very valuable as you develop a consolidation plan.
3.) Wear analysis - use sampling as an early warning on bearing failure
In the January-February 2013 issue of Machinery Lubrication, Steffen Bots provided a very good overview of grease sampling and analysis that is a recommended read if you want more details on grease analysis.
