With the higher rotational speeds and loads in bearings, the gaseous cavitation becomes more and cannot be ignorable in the bearing designs. However, there is no enough research in non-equilibrium ...
Wafer metrology systems require extremely high geometric precision of all involved motion systems. Air bearing slides, rotary tables and low-profile air bearing Z-axis and tip/tilt stages provide the ...
The accuracy of motion systems used in precision automation applications is significantly dependent on top-tier positioning stages and motion controllers. When designing a next-generation machine or ...
(Nanowerk News) PI’s air bearing motion product line is expanding. The new A-523 Z-Tip-Tilt low profile nano-positioning and alignment stage is based on a frictionless motion concept with air bearings ...
(Nanowerk News) PI, a global leader in motion control and nanopositioning systems, offers an ultra-low-profile Z-Tip-Tilt stage designed for demanding alignment applications in optics, semiconductors, ...
This video shows the principle and advantages of air bearing stages. Air bearing stages replace mechanical contact by a thin air film, avoiding wear, friction, vibration, and hysteresis effects. PI's ...
Seeing a heavy load slide around on nearly frictionless air bearings is pretty cool; it’s a little like how the puck levitates on an air hockey table. Commercial air bearings are available, of course, ...
Journal bearing design is complex. It involves optimizing clearances, bearing length, minimum film lubricant, viscosity, flow rate, and inlet slots. Design equations are available, but their solution ...
