Lubricated rolling contact devices, a method for lubricating rolling contact devices, and a composition for lubricating rolling contact devices

摘要

Lubricated rolling contact devices, especially full ceramic or hybrid ceramic rolling bearings, are designed so that the ceramic contact surface or surfaces are coated with a thin film formed from titanium dioxide in anatase form. The titanium dioxide film can be applied from a composition including particles of the titanium dioxide in grease or oil.
