Since there is no contact between the moving parts there is no sliding friction allowing fluid bearings to have lower friction wear and vibration than many other types of bearings. They can be broadly classified into two types.

Plain bearings also may be made of engineered plastics which provide excellent wear resistance and low friction in both dry and lubricated operating conditionsbeing injection molded they can be designed to almost any shape and produced from a variety of resins compounded with reinforcing fibers and solid lubricant.
Anti friction bearing wikipedia. A pillow block usually refers to a housing with an included anti friction bearing. As often as i use and recommend the use of anti seize as the reader might think i sell the stuff. A pillow block refers to any mounted bearing wherein the mounted shaft is in a parallel plane to the mounting surface and perpendicular to the center line of the mounting holes as contrasted with various types of flange blocks or flange units.
Fluid bearings are bearings in which the load is supported by a thin layer of rapidly moving pressurized liquid or gas between the bearing surfaces. It is friction for example that slows down a ball rolling on grass and causes the blade of a saw cutting wood to get hot. The resistance to movement that occurs when two objects are in contact.
