Diaphragm Air Cylinders

Product catalog summary

Overview of Rolling Diaphragm Air Cylinders
The Rolling Diaphragm Air Cylinder is designed for friction-free operation, featuring super sensitivity, no lubrication requirement, low hysteresis, no blow-by leakage, and adaptability to wide temperature variations. These cylinders are suitable for applications such as web tensioners, valve actuators, and impact absorbers.

Diaphragm Design
The rolling diaphragm is a durable, flexible membrane made from fabric-reinforced elastomer, ensuring a frictionless seal and operating in temperatures from -75°F to 400°F.

Ultra Cylinders
Ultra Cylinders are designed for minimal friction applications, combining rolling diaphragm seals with linear ball bearings and hardened steel rods for near-zero friction operation.

Modifications and Custom Devices
Standard cylinders can be customized to meet specific needs, including changes in diaphragm, bearing, or rod materials. ControlAir offers custom diaphragm devices with quick prototype delivery.

Operating Information
Cylinders operate on plant air up to 145 psi and temperatures from -40°F to 225°F, with custom materials extending this range to -75°F to 400°F. Modifications are available for hydraulic or liquid pressurized applications.

Materials
Cylinders are constructed from anodized aluminum or steel, with components like chrome-plated steel rods and sintered bronze bearings.

Operating Parameters
Specifications for single and double-acting cylinders include effective area, stroke, initial spring force, and spring rate.

Ordering Information
Instructions for ordering diaphragm air cylinders include types, sizes, stroke options, rod threads, mount types, and standard options.

Small Bore and Low-Cost Cylinders
MiniMights offer compact, friction-free performance, while low-cost cylinders provide economical options with similar features.

Repair Kits
Repair kits are available for maintenance, including components like diaphragms, bearings, and rod wiper rings.
