Rolling Diaphragm Air Cylinders The friction free alternative

THE “ROLLING DIAPHRAGM” AIR CYLINDER The advent of the long stroke rolling diaphragm as a means of low-friction dynamic sealing has led to the development of our Diaphragm Air Cylinder. These cylinders provide virtually frictionless conversion of pneumatic pressure to linear force, and offer such operating features as: • • • • • MODIFICATIONS Our standard Diaphragm Air Cylinders are easily modified to meet individual customer requirements. Modifications can include, but are not limited to, diaphragm, bearing, or rod materials, rod configurations, and spring design. Our engineering staff is...
