This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X1200S, 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 SU40X1200S
The AirTAC SU32~50 Standard Cylinder SU40X1200S is a double-acting profile-type standard cylinder with a Ø40mm bore and 1200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X1200S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X1200S
The AirTAC SU40X1200S is a discontinued double-acting profile cylinder with a 40mm bore and 1200mm stroke. Delivering 628N push force at 0.5MPa, its direct replacement is the SAU40X1200S, preserving the original 1/4" port, M12x1.25 rod thread, and SC-series mounting compatibility.
This compact extruded-aluminum body is shorter than equivalent ISO cylinders. Note the -S magnet used legacy CS1-B/DS1-B switches; the SAU successor requires CMSG/DMSG/EMSG sensors, and adds an optional SAUF built-in valve.

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 SAU40X1200S 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 SU40X1200S Is Used
Long-Reach Diversion
Pushes packages across a wide sorting belt over the full 1200mm extension, utilizing the 628N force to deflect heavy cartons reliably at speed.
High-Bay Extraction
Extracts totes from deep shelving racks where the compact profile body saves space while the long stroke reaches deep into storage lanes.
Material Transfer
Shifts workpieces between distant machine stations, requiring external guide rails to support the rod over the 1200mm travel distance.
Replacing the Airtac SU32~50 Standard Cylinder SU40X1200S with the SAU40X1200S
To replace this SU40X1200S, order the SAU40X1200S, verifying your 1/4" port, M12x1.25 thread, and SC-series mounting. Because the -S magnet utilized legacy CS1-B/DS1-B switches, you must upgrade to CMSG/DMSG/EMSG sensors on the SAU. If downsizing, a 32mm bore yields 402N push; if upsizing, a 50mm bore provides 982N at 0.5MPa. For load holding, standard cylinders drift without live air—use an external rod lock or pilot-operated check valve, as cushions only decelerate. The 1200mm stroke demands external guides to prevent rod bending under side loads. Consider the SAUF variant if you need a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU40X1200S
- ✓ 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 SU40X1200S FAQ
Yes, the SU40X1200S is discontinued. The direct replacement is the AirTAC SAU40X1200S. It matches the 40mm bore, 1200mm stroke, 628N force, 1/4" port, and SC-series mounting, but the SAU uses current CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
The 40mm bore features a 1/4" air port. At 0.5MPa it provides 628N push and 528N pull force. At 0.7MPa push is 879N, at 0.9MPa it is 1130N, and the theoretical maximum is 128kgf at 1.0MPa. Operating speed is 30-800mm/s.
