Lubrication life of cylindrical roller bearings for traction motors of railway vehicles (Effects of bearing temperature, vibration acceleration, and grease mass)

Nihon Kikai Gakkai ronbunshu
In general, the life of a rolling bearing is calculated as the total number of rotations until rolling fatigue occurs on the raceway. However, when rolling bearings are used under light loads and high rotational speeds, they are damaged not by rolling ...

Titanium carbide coatings for aerospace ball bearings [PDF]

In conventional ball bearings, steel to steel contacts between the balls and the raceways are at the origin of microwelds which lead to material transfer, surface roughening, lubricant breakdown, and finally to a loss in the bearing performances.

An evaluation of grease type ball bearing lubricants operating in various environments [PDF]

Because many future spacecraft or space stations will require mechanisms to operate for long periods of time in environments which are adverse to most bearing lubricants, a series of tests has been completed to evaluate 38 grease type lubricants in R-4 ...
