Detailed Information on Types of Bearing Lubriion

Lubriion provides a thin film between the contact areas in a bearing to reduce friction, dissipate heat and inhibit corrosion on balls and raceways. The lubricant will affect maximum running speed and temperature, torque level, noise level and, ultimately, bearing life.

How Fluid Film Bearings Work - Waukesha Bearings

Operating Principle In a fluid film bearing, the stationary and rotating surfaces are separated by a thin film of lubricant, such as oil, air, water or process fluid. In a hydrodynamic fluid film bearing, the film pressure that separates the surfaces is created by the relative motion (rotation) of the surfaces as the lubricant is pulled into a converging geometry between the surfaces.

Thin Film Lubriion | SpringerLink

Thin film lubriion (TFL) is a lubriion regime with a film thickness of a few nanometers to tens of nanometers, which can be thought of as the lubriion regime between elastohydrodynamic lubriion (EHL) and boundary lubriion, or extended boundary lubriion. Some also call it thin elastohydrodynamic lubriion.
