Air Bearing Table

Air bearing rotary tables.

Air bearing table.

Planar xy table consists of moving element called forcer which glides on the frictionless air bearings over the special waffle like surface called platen. Make air bearings that are robust simple to use inexpensive and available off the shelf. Planar forcer contains two or four linear motoring modules oriented 90 degrees to each other. The porous media design takes this all a step further.

All hovair automotive air bearing tables have a patented starbase design utilizing six heavy duty air bearings that are used to float the table top. Air bearings in general present an improved reliability over traditional bearings because there are no moving parts to fail. The air bearing with vacuum preload and a constant bearing gap height floats contact less on top of the rotary table. Air bearing tables allow your production facility flow to become better especially when it comes to cycle time and the time it takes to do product change over.

Planar xy table can operate in any orientation side wall upside down. High precision needle roller bearing maintains radial accuracy. Air supply must be clean dry to 0 f dew point and filtered to 0 25 µm or better. Abtech s precision air bearing rotary tables address the metrology needs for different weights and part size.

To protect air bearing against under pressure an in line pressure switch tied to the motion controller is recommended. Recommend nitrogen at 99 9 purity. Air bearing rotary tables when rotating the table top and work load are supported on air bearings whose freedom from friction contributes to the extremely high positional accuracy. Adjustment slider for optics production the linear slider which is air guided and statically determined guarantees a high precision positioning of the optical component before grinding.

Built for the most demanding applications every table provides ultra smooth motion sub micron accuracy and absolute repeatability. The purpose of this guide is to answer the common questions that designers have when first considering air bearings as well as to provide detailed information that will help ensure the success of your advanced application.
