SMC Standard Threads on NFPA Cylinders

Effective July 13th, 2020 - SMC Noblesville will expand the NCA1 series to include additional NFPA standard rod threads.  All NFPA standard rod ends were not initially released with NCA1 as a standard How to Order option and thus required a Simple Special/RFS for modification.  However, due to increased customer demand over the years and to benchmark the NFPA market offering, we have now standardized the rod thread modifications.

SMC NCA1 Air Cylinder Available from Scott Equipment CompanyThe NCA1 series is the NFPA interchangeable tie-rod actuator and is available in bore sizes 1.5" to 8".  Previously, the only standard rod thread option on NCA1 was a "Small Male" (Nil) thread.  The new NFPA rod thread options are being added are:

  • Short Female(SF)
  • Intermediate Male (IM)
  • Flanged (F)
  • Full Male (FM)
  • Plain (PL)

Previously requesting the above rod thread changes required an RFS (Request For Special).

The current NCA1 rod end standard is "Small Male" (Nil).  The additional thread options, listed above, are valid on the entire NCA1 series with the following exceptions:

  • Not valid with K (non-rotating), W (double rod), M (Male rod stud), KW (non-rotating, double rod)
  • Not valid above cylinder stroke of 60.00"
  • Not valid with J (Nylon Boot) or K (Neoprene Boot)
  • Not valid with X-Options: XB7 (low temp), XC8 (adjustable stroke extension), XC11 (dual operation/single rod), and X119US (non-rotating oversized rod)
