2. Mixed film (or elastohydrodynamic) lubrication is where most ball and roller bearings and high speed gears are found. Within this area keys to the wear rate are the viscosity, the cleanliness of the lubricant, and the deformation of the mating surfaces. With the extremely small film thickness, the additives that should be used in these lubricants are limited.

3. Hydrodynamic lubrication, also called full film lubrication is where the combination of lubricant and operating properties results in true separation of the pieces and very low wear rates result. It is in this range that minimum wear and maximum efficiency take place. Plain bearings are commonly found in large motors, internal combustion engines, and power generation equipment.
