If you need precision control during an inspection process then look to New Way® Air Bearings. Our Precision Zone line of air bars combines our Porous Media Technology™ with a tighter array of vacuum pressure holes. This permits 25-micron fly heights with a control range of 5 microns. The increased stiffness of our Precision Zone line is stable to 1 nanometer. With consistent flatness across the entire surface, these air bars are ideal for inspecting small areas during conveyance.
Our air bars are constructed from a soft carbon substrate that is naturally porous and won’t scratch delicate materials. Air flow through the bars is regulated by the millions of submicron holes to create a stable and stiff air cushion between the air bar and your materials. Production will never be interrupted by crashes since pressure gradients are essentially eliminated. The non-contact nature of our air bars means you never have to worry about your materials being damaged by the conveyor.
Our air bars are most commonly used in the flat panel display and solar panel manufacturing processes. The Precision Zone air bars are also useful for inspecting specific areas of semiconductor wafers or other materials that require high-level analysis for inconsistencies.
The Precision Zone air bars can be easily combined with our other air bars to provide superior flatness and stability in a desired region of the material. The vacuum pressure also reduces floating when the material moves on and off the air bars.
The Precision Zone bar measures up to its name as our highest level of precision for fly height and control range, ideal for inspecting and analyzing specific areas of interest. The design ensures the vacuum pressure and air gaps are the same across the entire bar. This superior stability enables analysis and inspection of a greater percentage of the entire glass sheet.
