TYPES OF AIR BEARING
 There are basically two types of air
bearing:
1)Aerostatic : 2)Aerodynamic:
1. AEROSTATIC BEARING(A-TYPE)
 A-type air bearings are a high-lift bearing which,
cause the load to lift vertically away ...
2. AERODYNAMIC BEARING (B-TYPE)
 B-type air bearings cause their loads to lift away
from the floor surface just enough to...

and floated the load. Compressed...
APPLICATION
 Lifting weights
 NOTE: We can lift more than 5 tons of weights
without any efforts.
APPLICATION
 Hover craft:
Used for transporting passengers on land as well
as water.
FUTURE SCOPE
 Future Vehicles can be designed using this
technology.
ADVANTAGES
 LOW FRICTION
 NO LUBRICATION REQUIRED
 LOW HEAT GENERATION
 LONG LIFE AND LONG LASTING
 MAINTAINANCE FREE
DISADVANTAGE
 HIGH GEOMETRY ACCURACY DURING
MANUFACTURING.
 CLEAN AND DRY SUPPLY OF PRESSURIZED
AIR.
 HIGH PRICING.
CONCLUSION
By stating the above points we can say that air
bearing is the perfect alternative for carrying and
transportin...

  3. 3. WHAT IS AIR BEARING?? An air bearing is a non-contacting system where a gas film (typically air) acts as the lubricant that separates the two surfaces in relative motion.
  4. 4. WHY AIR BEARING ?? • FRICTION Less Friction as compared to rolling and plain bearing • WEARIBILITY Materials used in other bearing eventually gets used up with time, which requires replacement. • LUBRICATION Unlike other bearing ,no lubrication is required.
  5. 5. TYPES OF AIR BEARING  There are basically two types of air bearing: 1)Aerostatic : 2)Aerodynamic:
  6. 6. 1. AEROSTATIC BEARING(A-TYPE)  A-type air bearings are a high-lift bearing which, cause the load to lift vertically away from the floor surface as much as 3 inches.  These bearings are used when vertical lift is required before floating the load away.
  7. 7. 2. AERODYNAMIC BEARING (B-TYPE)  B-type air bearings cause their loads to lift away from the floor surface just enough to allow them to be floated off to the destination.  B-type air bearings when use in series of four or more are capable of lifting and moving loads of up to 100 tons and beyond.
  8. 8. WORKING  Deflated : In the deflated stage, the air bearing , it is resting on the floor with most of the weight being supported by the center load pad.  Inflated : The second image shows the air bearing in an inflated form after it has formed a seal with the floor surface. At this stage, the load has not been engaged to float away from the floor.
  9. 9. WORKING  Load Lifted On Air : The above image shows the air bearing after it has engaged and floated the load. Compressed air will then start to escape from the bearing diaphragm into the area that is being contained by the floor seal.  The weight of the load causes the compressed air escaping out of the air bearing to force downward onto the floor surface thus causing the load to float away from the floor.
  10. 10. APPLICATION  Lifting weights  NOTE: We can lift more than 5 tons of weights without any efforts.
  11. 11. APPLICATION  Hover craft: Used for transporting passengers on land as well as water.
  12. 12. FUTURE SCOPE  Future Vehicles can be designed using this technology.
  13. 13. ADVANTAGES  LOW FRICTION  NO LUBRICATION REQUIRED  LOW HEAT GENERATION  LONG LIFE AND LONG LASTING  MAINTAINANCE FREE
  14. 14. DISADVANTAGE  HIGH GEOMETRY ACCURACY DURING MANUFACTURING.  CLEAN AND DRY SUPPLY OF PRESSURIZED AIR.  HIGH PRICING.
  15. 15. CONCLUSION By stating the above points we can say that air bearing is the perfect alternative for carrying and transporting heavy loads.
