Numatics S Series, Stainless Steel, NFPA, 1 1/2"-8" Bore

Numatics S Series, Stainless Steel, NFPA, 1 1/2"-8" Bore
The S Series is a stainless steel NFPA Interchangeable pneumatic cylinder line. It is designed and built to perform in the toughest "wash down" applications. The stainless steel construction provides outstanding corrosion resistance while including a multitude of favorable design features.
The S Series encompasses many of the same proven design features as our original NFPA Interchangeable cylinder, the A Series.
This includes an extra long rod bushing and a standard oversized wear band (located on the rear of the piston). Additionally, we have also included the proven "T" Seal piston seal configuration with carboxilated nitrile with self-lubricating PTFE® compound.
These are just a few of the features that make the S Series the Superior Stainless Steel NFPA Interchangeable air cylinder line.
Standard Specifications:
  • Meets NFPA specifications
  • Bore sizes from 1-1/2" through 8"
  • Piston rod diameters from 5/8" to 1-3/4"
  • Nominal pressure rating is 150 psi air
  • Standard temperature -10°F to 165° F(-23° C to 74° C)
  • All stainless steel construction, except piston (aluminum)
  • NPTF ports
  • Flexible port and cushion location
  • Head and cap are machined from 304 stainless steel for corrosion resistance.
  • Superior port design allows increased flow rate.
  • Piston is solid aluminum alloy that is strong and lightweight.
  • Extra wide wear band is located at the furthest point from the rod bushing to support maximum loading.
  • Piston seal is a carboxilated nitrile with PTFE compound for no lube added service. The seal design prevents rolling and seals at all pressures.
  • Tubing is 316 stainless steel with hard chrome plated inside diameter for long service.
  • Floating cushion design gives the fastest stroke reversal possible by providing instantaneous full flow to piston. Each cushion has flush, retained adjustment needle.
  • Rod seal is carboxilated nitrile with PTFE compound. The rounded lip design insures proper sealing and long life for no lube added service.
