Porous media air bearingssimPLe ConCePT; soPHisTiCaTed TeCHnoLogY!Frictionless motion can provide signifi cant advantages for many applications beyond those listed in this brochure. In fact, our standard air bearings are often found at the center of a unique solution implemented by ingenious engineers. Where the need for creativity is even greater, IBS Precision Engineering and New Way Air bearings often work with a customer to design and manufacture a custom porous media air bearing solution.

The porous material ensures equal air distribution under the bearing. Furthermore porous media air bearings are considerably better than conventional orifi ce bearings as far as bearing capacity, rigidity and air consumption go. In addition, the damping and crash resistance are better. The porous material makes the bearings less sensitive to damage.

Porous media air bearings provide new options for designers to push the envelope on precision, high speed, and high acceleration applications, while avoiding the traditional bearing-related problems of friction, wear and lubricants.

We can provide both standard and tailor-made air bearing solutions. In the brochure you can fi nd our standard air bearing product line, including :

FLaT round and reCTanguLar air bearingsOur fl at air bearings were the original standard, off-the-shelf, porous media air bearing product line, developed by New Way in the 1980’s. These versatile bearings are now available in round or rectangular confi gurations, ideal for a wide array of applications.

New Way fl at round porous media air bearings allow anyone to design and build their own custom air bearing assemblies. The round confi guration makes the most effi cient use of standard raw materials and ultra-precision manufacturing techniques, ensuring low-cost standard product availability.

They are also easy to apply. The gimbled mount allowsfor great fl exibility in tolerance and the threaded ballstuds make alignment simple. In addition to the standard product line (shown), custom fl at round bearings are also available, including replacement bearings for many CMM’s.

New Way air bushings are, essentially, a tube of porous media. Applying an air pressure of 4.1 bar creates an 8 µm layer of air between the air bushing and a shaft. The bushing is designed so that a self-centering force is created by the air fl ow, allowing for true 360° non-contact motion on round shafting. The paralleling force over the length of the bushing centers the shaft naturally, creating precise, non-contact motion in one axis.

The resulting frictionless motion eliminates the heat and vibration commonly associated with roller contact or re-circulating-ball linear way arrangements. The self-centering force also allows for higher than standard rotational speeds in spindle-type applications with all the benefi ts mentioned previously.

air sLidesdoVeTaiL air sLidesNew Way dovetail air slides combine an accurate guide with an air slide ready-fi t for installation. The dovetail guidebar can be end-supported, or continuously supported. A continuously supported dovetail will prevent the guidebar sag that can occur with a long span end-supported confi guration. The dovetail air slide features New Way’s lowest profi le linear track, and a slightly longer stage length than other assemblies. The dovetail also contains a space between the guidebar and stage where a linear motor or other driver can be mounted.

end suPPorTed air sLidesThe simplest of the linear motion assemblies, end-supported air slides provide a precise, integrated linear motion solution ready-fi t for installation. Designed specifi cally for situations where continuous support is impossible or impractical, the end supported air slide is engineered to minimize guidebar sag and provide straightness of motion and dynamic response often an order-of-magnitude better than conventional rolling-element bearings.

New Way air slides provide a local straightness (in X and Z) of 250 nanometers (0.25 microns) per 25mm travel and a maximum error (global) of 2 microns per 1000mm travel.

boXWaY air sLidesBoxway air slides are original integrated slide-andguide assembly. The guidebar for the boxway can be end-supported, or continuously-supported (preventing the sag inherent in long span endsupported confi gurations). Featuring a low profi le linear track, and a slightly wider stage than the New Way dovetail, the boxway also provides the largest load carrying capacity and the longest travel length.

airWaYsThe airway linear motion guide system is pre-engineered for simple swap-out with conventional rolling element bearing systems. With this new linear slide assembly, customers can simply remove the existing rolling element truck and rail, replace them with airway system, connect an air supply, and immediately experience the benefi ts of frictionless motion.

non-ConTaCT gLass-HandLingAIR BARS FOR FPD AND SOLAR APPLICATIONS

PreCision Zone air barsPrecision zone air bars are engineered for use under or near precision FPD or solar glass manufacturing processes or Automated Optical Inspection (AOI) stations. They provide a much higher level of precision, stiffness, and damping than traditional air bars. The vacuum holes are designed so that, with air pressure on, the fl ow through a vacuum hole is the same whether there is glass over it or not. Simple and smart. This also means that as the glass comes on and off the chuck, the vacuum pressures and air gaps remain the same.

These precision zone air bars provide ±5µm control, well within the focal range of most optical inspection systems. This is a signifi cant advantage over conventional methodologies or orifi ce-based air bars, especially for coating or AOI applications in Gen-10 or higher manufacturing lines. Superior stiffness provides for faster settling time and higher yield, without the scratching or breakage typical of competitive systems. And the larger the glass size, the bigger your advantage.

FLoTaTion Zone air bars The fl otation zone air bar provides FPD or solar manufacturers with improved non-contact glass-handling capability for conveying applications outside precision zones where the control provided by vacuum capability is unnecessary. Engineered to integrate perfectly with transition zone and precision zone air bars, these modular components allow for design continuity across your glass-handling, processing and /or inspection system.

Available in a rugged 80mm dovetail profi le, fl otation zone air bars are available from stock, and are easy to install, level, plumb, maintain, and replace, as separate components...or as part of a larger system, through Generation 10 and beyond.

Independentally or as part of a scalable system, fl otation zone air bars enable lower initial set-up costs and reduced operating expenditures. They are designed for use with compressed air systems or with simple, inexpensive blowers.

12

Flotation zone air bars

Transition zone air bars

Precision zone air bars

TransiTion Zone air barsThe transition zone air bar combines the best performance characteristics of the company’s H-Series (high speed) and L-Series (low airfl ow) air bars into a single hybrid design. This new profi le is also engineered to signifi cantly reduce both the system and the operating cost.

The single vacuum groove provides necessary control of the leading edge of the glass, while also enabling a greater fl y height range of 20 to 120 microns. These fl y heights have a stability of ±5 microns, well within the focal range of most inspection cameras. This makes the transition zone air bar ideal for FPD manufacturers looking for non-contact control of Flat Panel Display glass at 30 microns, and also for solar module manufacturers requiring 80 microns of fl y height.

The combination of air pressure evenly distributed through the entire surface of the conveyor, and vacuum pulling the glass down, and fl attening it, provides a high margin of safety against glass touch-down.Further, the transition zone air bar design enables components to be placed further apart in the array, and can even enable the glass to ‘jump’ 100mm spaces (over inspection or production zones), further reducing costs and offering fabs or machine builders additional design fl exibility.Finally, because these air bars are manufactured using porous media technology, which restricts the fl ow of air through the bearing surface, the compressed air required is signifi cantly less than that for competitive products; even the compressor size can be reduced for many applications.

VaCuum PreLoaded air bearings

mounTing ComPonenTsNew Way standard mounting components are well-thought-out and precision-engineered to make the integration of our standard product line easy.

The combination of air pressure and vacuum necessitates a different mounting methodology from New Way fl at air bearings. The typical socket would not provide for bi-directional stiffness because the ball would pull out. New Way has engineered a fl exure mount to provide equal stiffness in both directions, while providing a low pivot point. Because there is no stick-slip type friction in the fl exture mount, even the smallest amount of angular adjustment is possible.

FLeXure mounTsDesigned specifi cally for the mounting of New Way vacuum preloaded air bearings, these two-piece, aluminum fl exure mounts provide bi-directional stiffness, a low pivot point, and infi nitesimal angular adjustment.

Using a combination of air pressure and vacuum, New Way VPL air bearings hold themselves down while simultaneously lifting themselves from a guide surface. By adjusting the vacuum and the pressure separately, the fl y height and stiffness of these vacuum preloaded air bearings can be optimized.

This arrangement is ideal for applications where preloading is diffi cult or impossible. Obviously, there is a cost advantage because only one fl at guide surface is necessary. Opposed bearing preloading requires two fl at guide surfaces that are parallel.

There is also a signifi cant technical advantage. Both «x» and «y» axes can be supported by a single bearing plane. Further, the adjustability of fi lm thickness can be used for focusing, squaring and sub-micrometer vertical positioning over a range of several microns.
