Air is the only lubrication used; therefore air bearing technology is ideal where there must be no contamination of the work piece or working environment.
With the elimination of grease, oil and oil mist from the working environment, conditions remain cleaner when using air bearing spindles. Air bearings have no adverse effect on the environment, and are therefore ideal for use in cleanroom applications, such as in magnetic disk drive manufacture. Indeed, it is possible to operate specifically designed Westwind air bearing spindles in high vacuum conditions, as experienced in semiconductor silicon wafer manufacturing.
Typical clean room standard in which spindles can be operated in: Class 100. |
