The advent of the long stroke rolling diaphragm as a means of low-friction dynamic sealing has led to the development of ControlAir's line of Diaphragm Air Cylinders. These cylinders provide virtually frictionless conversion of pneumatic pressure to linear force. The fact that there is no stiction or blow-by of any kind ensures accuracy, repeatability and sensitivity unheard of from conventional sliding seal air cylinders.
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 the ControlAir Diaphragm Air Cylinder. These cylinders provide virtually frictionless conversion of pneumatic pressure to linear force,and offer such operating features as:
Absolutely No Lubrication Required
No Blow-By Leakage
Wide Temperature Variations.
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 longlasting 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.”
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.
Our Cylinders are rated to operate on plant air up to 145 psi (10 Bar) at a temperature range of -40° F to 225° F. Custom diaphragm materials can be used to permit our cylinders to operate at temperatures from -75° F to 400° F. Although ControlAir's standard line of cylinders are for air service only, modifications are available to accommodate hydraulic or liquid pressurized applications.
