This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X200, 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 SU40X200
The AirTAC Airtac SU32~50 Standard Cylinder SU40X200 is a double-acting profile-type standard cylinder with a Ø40mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X200, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X200
The AirTAC SU40X200 is a discontinued double-acting profile-type cylinder with a 40mm bore and 200mm stroke, delivering 628N push and 528N pull at 0.5MPa. AirTAC replaced this end-of-line unit with the SAU40X200 direct replacement. It shares the exact bore, stroke, output force, 1/4" port, and SC-series mounting hardware, ensuring a seamless physical swap.
Because this is a non-magnet SKU, it cannot accept a sensor. If you need position detection on the SAU40X200, order an -S variant and note that the SU's legacy CS1-B/DS1-B switches are replaced by current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X200 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAU40X200 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 SU40X200 Is Used
Package Diversion
Actuates a routing gate on a 40mm belt conveyor to sort parcels up to 32kg, utilising the 200mm stroke to clear the lane.
Clamp Actuation
Provides 377N of safe working clamping force to hold light aluminium extrusions in place during automated drilling.
Stopper Cylinder
Functions as a pneumatic stop for totes arriving at a packing station, absorbing impact via the adjustable 21mm cushions.
Replacing the Airtac SU32~50 Standard Cylinder SU40X200 with the SAU40X200
To replace this discontinued SU40X200 with the SAU40X200, verify your 40mm bore, 200mm stroke, 1/4" port, and M12x1.25 rod thread. Reusing existing AirTAC SC-series mounts is fully supported. This non-magnet version cannot host a sensor; if detection is needed, specify an SAU40X200-S and migrate to CMSG/DMSG/EMSG switches. Sizing both ways: a 32mm bore offers 402N push at 0.5MPa, while a 50mm bore yields 982N. The 200mm stroke is well under the 1200mm maximum, keeping rod-bending risk low. Remember, a standard cylinder drifts on air loss—the cushion only decelerates near stroke end—so add an external rod lock or pilot-operated check valve for held loads. The SAU family also adds a SAUF valve-integrated option the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU40X200
- ✓ 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 SU40X200 FAQ
Yes, the AirTAC SU40X200 is discontinued. The direct replacement is the SAU40X200, matching the 40mm bore, 200mm stroke, 628N force, 1/4" port, and SC-series mounting.
It delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. It cannot hold a load without live air; the cushions only decelerate, so use a rod lock for holding.
