Bearing Lubrication II

Most bearings operate with a fluid film -- oil, another liquid, or a gas. By far the largest number of bearings are oil lubricated. The oil film can be maintained through pumping by a pressurization system -- in which case the lubrication is termed hydrostatic. Or it can be maintained by a squeezing or wedging of lubricant produced by the rolling action of the bearing itself -- termed hydrodynamic lubrication. If loads are too high

Hydrostatic and Hydrodynamic Bearings
Hydrostatic bearings and hydrodynamic bearings are fluid film bearings that rely on a film of oil or air to create a clearance between the moving and stationary elements.
Plain Bearings and Sleeve Bearings
Plain bearings and sleeve bearings (also referred to as bushings or journal bearings) are used to constrain, guide or reduce friction in rotary or linear applications. They function via a sliding action.
Pillow Block Bearings
Pillow block bearings are mounted bearings that are used to provide load support for a rotating shaft’s axis. 
Flange Mounted Bearings
Flange mounted bearings are used when a shaft axis is perpendicular to the bearing mounting surface. They are available in 2, 3, or 4-hole configurations.
Lubricators and Lubrication Systems
Lubricators and lubrication systems are used to apply controlled or metered amounts of lubricant.
