Air Bearing Table

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 bearing table.

Make air bearings that are robust simple to use inexpensive and available off the shelf. Built for the most demanding applications every table provides ultra smooth motion sub micron accuracy and absolute repeatability. Air supply must be clean dry to 0 f dew point and filtered to 0 25 µm or better. Air bearing rotary tables.

Planar forcer contains two or four linear motoring modules oriented 90 degrees to each other. With the improved precision and crash resistant design the customer can be confident their precision rotary table is producing accurate results every time. Recommend nitrogen at 99 9 purity. 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.

Planar xy table consists of moving element called forcer which glides on the frictionless air bearings over the special waffle like surface called platen. High precision needle roller bearing maintains radial accuracy. Abtech s precision air bearing rotary tables address the metrology needs for different weights and part size. An air bearing is a non contacting system where a gas film usually air acts as the lubricant that separates the two surfaces in relative motion typically this being a rotating shaft and a stationary radial journal or axial thrust bearing.

The porous media design takes this all a step further. To protect air bearing against under pressure an in line pressure switch tied to the motion controller is recommended. 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. 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.

The air bearing with vacuum preload and a constant bearing gap height floats contact less on top of the rotary table. Planar xy table can operate in any orientation side wall upside down.
