Air bearing cylinder ‘’AC’’ series■Features-Air bearing is adopted for rod guide part.
-Since the rod and the guide are not in contact with eachother, there is no frictional resistance and super precise
control is possible. Also, there is no wear and dust
generation.

■Applications-Precision pressure control not possible with conventional cylinders.
-Precision tension control of printing machines and plastic production equipment etc.
