Elastohydrodynamic lubrication

Lubrication modified to take into consideration the elastic properties of the bearing material and the viscosity increase of the lubricant under concentrated load. In rolling element bearings, the bearing undergoes elastic deformation (flattening) as it rolls under load in the bearing race. This momentary flattening improves the hydrodynamic lubrication properties by converting point or line contact to surface-to-surface contact.
