The document discusses air bearings, including their types, working, applications, advantages, and disadvantages. It introduces air bearings as a type of non-contact bearing that uses a gas film like air to separate surfaces in relative motion. The advantages listed are low friction, no lubrication required, low heat generation, and long life. The disadvantages are the need for high manufacturing accuracy, a clean and dry supply of pressurized air, and high pricing.

3. INTRODUCTION
 A bearing is a machine element that constrains
relative motion to only the desired motion, and
reduces friction between moving parts.

4. ANOTHER DEFINITION:-
An air bearing is a non-contacting system where a
gas film (typically air) acts as the lubricant that
separates the two surface in relative motion.

12. ADVANTAGES:-
o LOW FRICTION
o NO LUBRICATION REQURIED
o LOW HEAT GENERATION
o LONG LIFE AND LONG LASTING
o MAINTAINANCE FREE

13. DISADVANTAGES:-
o HIGH GEOMETRY ACCURACY DURING
MANUFACTURING.
o CLEAN AND DRY SUPPLY OF PRESSURISED
AIR.
o HIGH PRICING.
