NUMATICS NFPA Series A Cylinders

Numatics, nfpa cyclinders, ontario, GTA, macromotion, canada

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" Seal 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.


Standard Specifications:


  • Meets NFPA specifications

  • Bore sizes from 1-1/2" through 6" ( 8" through 14" are Large Bore A Series)

  • Piston rod diameters from 5/8" to 1-3/4" (1-3/8" through 2-1/2" for Large Bore A Series)

  • Nominal pressure rating is 250 psi air

  • Standard temperature -10°F to 165° F(-23° C to 74° C)

  • NPTF ports

  • Flexible port and cushion location

  • Multitude of mounting options




  • The file hard (60 RC) high strength aluminum alloy tube provides a smooth corrosion free sealing surface and excellent abrasion resistance

  • Head and cap are machined from (6061-T6) solid aluminum bar and anodized for corrosion resistance. A recess at the piston mating surface allows the air to work on a larger effective piston area for faster breakaway

  • The longer cast iron rod bushing provides maximum load bearing support. The graphite-filled material offers the best bearing surface with hard chrome plated piston rod.

  • The carboxilated nitrile with PTFE compound is used in the rod seal. The rounded lip design insures proper sealing and long life for no lube added service.

  • Rod wiper construction is a highly durable polyurethane.

  • High strength steel (100,000 psi minimum yield) piston rod has a ground, polished and hard chrome plated surface providing maximum life of bushing and seals.

  • The bushing retainer allows cartridge removal without disassembly.

  • Tie rods are 100,000 psi minimum yield steel for maximum holding power. Tie rod threads are rolled for strength and engagement.

  • The extra wide wear band is located at the furthest point from the rod bushing to support maximum loading.

  • The solid aluminum alloy piston is strong and lightweight.

  • The floating cushion design gives the fastest stroke reversal possible by providing instantaneous full flow to piston. Each cushion has a flush, retained adjustment needle.

  • The tube seals are compression type and reusable.

  • Improved port design allows increased flow rate.
