NFPA InterchangeableMax Operating Pressure: 250 PSI (17 bar)
Bore Size: 1.5 to 6 in (38 to 152 mm)
The A Series is an aluminum NFPA Interchangeable cylinder line that is designed and built to excel in the most demanding applications. The A Series encompasses many value-added features such as an extra long graphite filled cast iron rod bushing and a standard oversized wear band that is located on the rear of the piston. Additionally, the A Series includes the well-proven “T” piston seal configuration made from carboxilated nitrile with self-lubricating PTFE compound. These are just a sample of the features that make the A Series the superior NFPA Interchangeable air cylinder line.

The tube is hard coat anodized. The hard coating is an electrochemical process, which produces a very dense surface of aluminum oxide. This surface has extreme hardness (60 Rc), excellent wear and corrosion resistance, and a low coefficient of friction.
The end caps are accurately machined from (6061-T6) solid aluminum bar stock. They are anodized for corrosion resistance. Additionally, a recess on the piston-mating surface (at both ends) enables the air to work on a larger piston area for effortless breakaway.
The A Series includes a graphite filled, cast iron rod bushing that is extra long in length. Graphite filled offers the best bearing surface when using a hard chrome plated steel piston rod. Cast iron provides maximum resistance against wear. The added length adds superior alignment and support of the piston rod as well as provides maximum load bearing support.
The carboxilated nitrile with PTFE compound rod seal is selflubricating and durable. The rounded lip design ensures proper sealing and long life.
The standard rod wiper construction is a highly durable polyurethane.
High strength steel (100,000 psi minimum yield) piston rod has a ground, polished, and chrome plated surface. This surface provides maximum life for both the rod bushing and the seals.
The bushing retainer allows cartridge removal (cylinder repair) without complete disassembly.
The tie rods are 100,000 psi minimum yield steel for maximum holding power. The threads are roll formed for superior strength and engagement.
The piston seal is a carboxilated nitrile with PTFE compound making it self-lubricating. The “T” with back-up ring construction prevents rolling and seals at all pressures.
The wear band is a stable, lubricating strip located on the piston. We separated the load bearing points by locating the wear band at the rear of the piston. This maximizes column strength at full extension.
The solid aluminum alloy piston is strong and durable.
The floating cushion seal design enables rapid stroke reversal by providing instantaneous full flow to the piston. Each cushion has a flush, retained adjustment needle.
Tube End Seal
The tube end seals are compression type and reusable.
Our enhanced port design enables the cylinder to work more efficiently. Through the use of precise machining depths and tool shape, we are able to smooth the flow path into and out of the cylinder.
