CONVEYOR AIR BEARINGS - H-SERIES

New Way developed the high speed conveyor air bearing (also called air bar) to provide FPD or Solar manufacturers with improved non-contact control of their substrates at high manufacturing process speeds, with lower initial set-up costs and reduced operating expenditures. A large vacuum area results in a smaller air gap, providing higher stiffness and improved damping. The large, attractive forces give excellent flattening ability for more reliable glass control. This, combined with the constant low pressure at the leading edge of the glass, prevents it from lifting off the air bar and ‘sailing’ at high speeds.

As designers have tried to reduce or eliminate damage caused by the substrate contacting conventional air bars, they have increased the fly height, but the problem remains. That’s because a large air gap acts like an undamped spring, allowing waves to propagate, and increasing the probability of contact with the air bar, resulting in scratches or glass fracture. Although it might seem counterintuitive, New Way has found that a lower air gap actually reduces the chance for contact, since the stiffness of an air film is inversely proportional to the air gap. Air gaps should be less than 50 microns for the best control of FPD or Solar glass. With New Way Porous Media Technology, that smaller air gap significantly reduces the probability of contact with the bearing surface, and the resulting scratches or glass fracture.

4 different types of conveyor air bearings are available: (Custom types are available on request.)

 

500 mm x 100 mm (product code S22100H500)
Smallest of the New Way H-Series (high speed) conveyor air bearing line, the 500mm size is designed to provide the shorter length necessary to finish out the construction of arrays for all different fpd glass generations. New Way Porous Media® Technology delivers controlled, non-contact glass handling capability for high-speed applications. These modular components are available from stock and easy to install, level, plumb, maintain, replace and change.

 

750 mm x 100 mm (product code S22100H750)
The original New Way H-Series (high speed) conveyor air bearing, now the second-smallest in the line, the 750mm size is proportioned for efficient use when building arrays required for the smallest to the largest glass generations. New Way Porous Media® Technology delivers controlled, non-contact glass handling capability for high-speed applications. These modular components are available from stock and easy to install, level, plumb, maintain, replace and change.

 

1000 mm x 100 mm (product code S22100H1000)
Second largest of the New Way H-Series (high speed) conveyor air bearing line, the 1000mm size provides another long configuration alternative for engineers arranging the component parts in arrays for the manufacture or inspection of the very largest glass generations. New Way Porous Media® Technology delivers controlled, non-contact glass handling capability for high-speed applications. These modular components are available from stock and easy to install, level, plumb, maintain, replace and change.

 

1250 mm x 100 mm (product code S22100H1250)
Largest of the New Way H-Series (high speed) conveyor air bearing line, the 1250mm size provides the length necessary for maximum efficiency when building the arrays required for the largest glass generations. New Way Porous Media® Technology delivers controlled, non-contact glass handling capability for high-speed applications. These modular components are available from stock and easy to install, level, plumb, maintain, replace and change.
