... metal particles near the craters, and energy-dispersive x-ray analysis showed that slivers recovered from the grease had the same composition as the bearing raceway and balls. Based on these observations, it was concluded that the bearing failed due to electrostatic discharge, which would have led...

... is particularly important to reduce galling. Two basic types of lubricants used for extruding titanium are greases and glasses. Metallic copper coatings are also used with grease lubricants, particularly in extruding the commercially pure grades. Grease mixtures offer little or no thermal protection for the die...

..., and oils and greases add lubricant viscosity effects. Unlubricated, and in continuous use, the bearing elements would be rubbing all the time and they would fail from wear or rolling contact fatigue (pits and spalling in the balls and raceways). The life of the bearing would be only a fraction of the life...
