Pneumatic Cylinders, Heavy Duty Steel -
Miller AV and AVN Series

AV and AVN Series heavy duty steel pneumatic cylinders offer advanced features like the bolted bushing assembly, adjustable floating cushions, case hardened piston rods and high strength tie rods with rolled threads - compare and choose the Miller advantage.

Miller AV and AVN Series steel pneumatic cylinders provide value through proven reliability, efficient performance and the quality that you expect from every Miller cylinder. Each AV and AVN Series cylinder incorporates design features that are superior in a 250 psi rated cylinder. These features include the bolted bushing, adjustable floating cushions, hard chrome plated piston rods and high strength tie rods with rolled threads rather than cut threads.

The AV Series Serrated Lip Rod Seal in combination with the Double-Service Wiperseal™ comprises a sealing system that delivers leak free performance. The one-piece piston design is piloted to the piston rod, assuring concentricity and the wide piston surface contacting cylinder bore reduces bearing loads. Pressure actuated O-ring Body End Seals provide leak free service.

AVN Series non-lube air cylinders feature rounded lip rod and piston seals that glide over PTFE based lubricant to provide long seal and bearing life without the use of air line lubricators. As the cylinder strokes, no oil is expelled into the atmosphere with exhaust air.

Every AV Series and AVN Series cylinder is individually tested before leaving our plant to assure proper performance and leak free operation and comes with an eighteen month warranty.
