Cylinders & Actuators - NFPA - Numatics Series A
Double Acting - Aluminum NFPA - Cushioning - 1-1/2 to 6
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:
1）Meets NFPA specifications
2）Bore sizes from 1-1/2" through 6" ( 8" through 14" are Large Bore A Series)
3）Piston rod diameters from 5/8" to 1-3/4" (1-3/8" through 2-1/2" for Large Bore A Series)
4）Nominal pressure rating is 250 psi air
5）Standard temperature -10°F to 165° F(-23° C to 74° C)
6）NPTF ports
7）Flexible port and cushion location
8）Multitude of mounting options
Features:
1）The file hard (60 RC) high strength aluminum alloy tube provides a smooth corrosion free sealing surface and excellent abrasion resistance
2）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
3）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.
4）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.
5）Rod wiper construction is a highly durable polyurethane.
6）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.
7）The bushing retainer allows cartridge removal without disassembly.
8）Tie rods are 100,000 psi minimum yield steel for maximum holding power. Tie rod threads are rolled for strength and engagement.
9）The extra wide wear band is located at the furthest point from the rod bushing to support maximum loading.
10）The solid aluminum alloy piston is strong and lightweight.
11）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.
12）The tube seals are compression type and reusable.
13）Improved port design allows increased flow rate.
