The Illinois Pneumatics' Diaphragm Air Cylinder combines the field proven rolling diaphragm design with today's higher strength, lighter weight materials to provide a cylinder that lasts longer, yet weighs less than conventional diaphragm air cylinders. Illinois Pneumatics prides itself in modifying standard cylinders for special use.

CYLINDER TUBE-Manufactured from 6063-T6 aluminum, which is completely anodized to assure maximum corrosion protection. Custom anodizing colors are available as well as other exterior finishes.*

END CAPS-High grade aluminum alloy end caps offer standard mounting hole configurations or custom patterns.*

*size 36 cylinders use chrome plated and ground steel tubes with
cast iron end caps.

PISTON RODS-Piston rods are made of hard chrome plated ground and polished steel with a minimum yield of 100,000 psi. Ground and chrome plated stainless steel piston rods are also available.

PISTON-Pistons are aluminum alloy for light weight and low inertia.

ROD BEARINGS-Standard single (SA series) and double acting (DA series) cylinders utilize impregnated sintered bronze bearings with a urethane rod wiper for smooth operation and long life. LB series cylinders utilize linear bearings for applications requiring minimum friction and maximum sensitivity. These cylinders combine the advantages of the rolling diaphragm seal with the extremely low friction linear bearing and a case hardened steel piston rod. Linear bearing cylinders are available in long stroke only. CB series cylinders utilize composite bearings and case hardened steel rods for applications requiring the highest load capacity. With load capacities ten to twenty times greater than other bearings and a co-efficient of friction as low as .125 average, composite bearings are the ultimate in performance. Unlike other bearing designs, composite bearings will not fail catastrophically.

DIAPHRAGMS-Illinois Pneumatics' fabric reinforced diaphragms are manufactured from neoprene rubber with a woven polyester fabric. Rated to operate from -25 degrees to 250 degrees F. Optional diaphragm materials such as viton or silicone can be selected to operate from -75 degrees to 400 degrees F. Consult factory for application requirements.

FASTENERS-Manufactured from heat treated, high carbon alloys for strength and resistance to corrosion. Other materials such as stainless steel are also available.
