The "Fujikura Composite Air Bearing Cylinder" is an air cylinder that employs air bearings in the rod guide section. Since there is no contact between the rod and the guide, it features no sliding resistance, wear, or dust generation. 【Features】 - There is no contact between the rod and the guide, resulting in no sliding resistance, wear, or dust generation. - Compared to other types of air bearings, it excels in resistance to lateral loads. - Due to the lack of resistance, precise driving at low pressure and low speed is possible. - Since there is no resistance between the rod and the guide, stick-slip does not occur during operation. *Please refer to the PDF data available for download for the catalog of the "Fujikura Composite Air Bearing Cylinder."
