This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X1400S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SU32~50 Standard Cylinder SU40X1400S
The AirTAC SU32~50 Standard Cylinder SU40X1400S is a double-acting profile-type standard cylinder with a Ø40mm bore and 1400mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X1400S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X1400S
The AirTAC SU40X1400S is a discontinued double-acting profile-type cylinder with a 40mm bore and a 1400mm stroke. Because 1400mm exceeds the 1200mm standard maximum for this bore, it is a non-standard, made-to-order length. It delivers 628N push and 528N pull at 0.5MPa, operating at 30-800mm/s through a 1/4" port. The direct replacement is the SAU40X1400S, matching the body, force, port size, and SC-series mounting.
When upgrading, note that the SAU uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S model, and the SAUF variant adds a built-in valve the SU lacked. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X1400S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SU32~50 Standard Cylinder SU40X1400S Is Used
Long-Reach Diversion
Pushes packages across a wide sorting belt using the 1400mm stroke, applying up to 377N of safe working force to redirect items without stalling.
High-Bay Extraction
Extracts totes from deep shelving racks where the compact profile saves space and the 32kg vertical lift margin handles fully loaded bins.
Extended Stroke Ejection
Ejects molded parts from a deep press bed, requiring external guide rails to prevent rod bending over the 1400mm extension.
Replacing the Airtac SU32~50 Standard Cylinder SU40X1400S with the SAU40X1400S
To replace this discontinued SU40X1400S, order the SAU40X1400S direct equivalent, keeping the 40mm bore, 1400mm non-standard stroke, M12x1.25 rod thread, 1/4" port, and SC-series mounts. If the 1400mm length is flexible, dropping to the 1200mm standard max avoids the made-to-order delay. For higher force, the 50mm bore provides 982N push at 0.5MPa; for lighter duties, the 32mm bore offers 402N. Because the 1400mm stroke risks rod bending under side-load, fit an external guide. The -S magnet means switching to CMSG/DMSG/EMSG sensors on the SAU. A plain cylinder drifts on air loss—the cushion only decelerates—so use a pilot-operated check valve or rod lock to hold loads. The SAUF valve-integrated option can simplify plumbing if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU40X1400S
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU32~50 Standard Cylinder SU40X1400S FAQ
Yes, the SU40X1400S is discontinued. The direct replacement is the SAU40X1400S. It matches the 40mm bore, 1400mm stroke, 628N push force at 0.5MPa, 1/4" port, and SC-series mounting. You must upgrade your sensors: the SAU uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
This double-acting cylinder delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, 1130N at 0.9MPa, and a theoretical max of 128kgf at 1.0MPa. The 1400mm stroke exceeds the 1200mm standard maximum for a 40mm bore, making it a non-standard, made-to-order length. It runs at 30-800mm/s with a 21mm adjustable cushion at both ends.
