Please explain on what basis can sliding contact bearings be classified?
Answer:
Sliding contact bearings can be classified on the basis of the thickness of the lubricating agent layer between the bearing and the journal. They can be classified as follows:
☛ > Thick film bearings: These type of bearings have their working surface separated by a layer of the lubricant. They are also known as hydrodynamic lubricated bearings.
☛ > Thin film bearings: In this type of bearings the surfaces are partially in direct contact with each other even after the presence of a lubricant. The other name for such type of bearings is boundary lubricated bearings.
☛ > Zero Film Bearings: These type of bearings as their name suggests have no lubricant present between the contact layers.
☛ > Externally or hydrostatically pressurized lubricated bearings: These bearings are able to without any relative motion support steady loads.
