Diaphragm Air Cylinders: The advent of the long stroke rolling diaphragm as a means of low-friction dynamic sealing has led to the development of the ControlAir Diaphragm Air Cylinder. The rolling diaphragm creates the perfect seal for friction free cylinders. It is a durable, flexible membrane shaped like a top hat with the peak of the hat fastened to the end of the piston and the “brim” clamped to the cylinder cap. Inside of the cylinder this forms a long lasting frictionless seal between the piston head and cylinder wall. The fabric reinforced elastomer rolling diaphragms are produced utilizing a microprocessor controlled process that is recognized as the leading edge mode of production. Custom diaphragm material design allows for operation of the cylinders at temperatures from -75°F to 400°F.
Ultra Cylinders-Linear Ball Bearings: For applications where the absolute minimum in friction free performance is required, ControlAir has developed the Ultra Cylinder. These cylinders combine the advantages of the rolling diaphragm seal with Grade “A” linear ball bearings and a hardened steel rod to produce virtually zero friction operation. For the ultimate in precise response to small pressure variations, choose “The Ultra.”
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.
Applications: The performance advantages of our Diaphragm Air Cylinders make them ideal for applications such as Web Tensioners, Dancer Roll Tensioners, Roll Loaders, Valve Actuators, Accumulators, Positioners, and Impact Absorbers to name a few.
