Overgreasing causes bearings to run hot, which reduces grease life, according to Chris Decker, a grease formulator. However, undergreasing also creates problems, including bearing failure.

To accurately determine regreasing schedules, wu suggest the user check the operator manuals or work with their grease supplier to evaluate five factors:
1. Equipment type
2. Grease type
3. External contaminants
4. Environmental and operating temperatures
5. Operating speeds and loads
