This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X600STC, 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 SU40X600STC
The AirTAC SU32~50 Standard Cylinder SU40X600STC is a double-acting profile-type standard cylinder with a Ø40mm bore and 600mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X600STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X600STC
The AirTAC SU40X600STC is a discontinued double-acting profile-type cylinder with a 40mm bore and 600mm stroke. It delivers 628N push and 528N pull at 0.5MPa through a 1/4" port. AirTAC replaced this unit with the SAU40X600STC, a direct upgrade retaining the exact body dimensions, force, and SC-series TC mounting interface.
When upgrading, note the SAU replacement uses current CMSG/DMSG/EMSG sensors instead of this model's legacy CS1-B/DS1-B switches, and the SAUF variant adds a built-in valve the SU lacked. Because the 600mm stroke invites rod bending, use external guides to prevent side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X600STC 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 SAU40X600STC 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 SU40X600STC Is Used
Long-Stroke Diversion
Pushes packages across a 600mm conveyor lane using the 628N push force at 0.5MPa, requiring external guides to handle the extended rod length safely.
Pneumatic Ejector
Ejects machined parts from a fixture over a 600mm distance, relying on the adjustable 21mm air cushions to decelerate the payload at stroke end.
Replacing the Airtac SU32~50 Standard Cylinder SU40X600STC with the SAU40X600STC
To replace the SU40X600STC, order the SAU40X600STC direct equivalent, verifying the 40mm bore, 600mm stroke, 1/4" port, and TC mounting accessory are retained. If your application used the -S magnet for position sensing, you must switch to CMSG/DMSG/EMSG switches as the legacy CS1-B/DS1-B sensors are obsolete. For force verification, this bore provides 628N push at 0.5MPa; if more force is needed, step up to a 50mm bore (982N push). At 600mm stroke, external guides are critical to prevent rod bending and premature seal wear. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock for suspended loads. The SAUF valve-integrated option is available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU40X600STC
- ✓ 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 SU40X600STC FAQ
Yes, the AirTAC SU40X600STC is discontinued. The direct replacement is the SAU40X600STC, which shares the same 40mm bore, 600mm stroke, 1/4" port, force output, and TC mounting interface.
This 40mm bore cylinder delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a 128kgf theoretical max at 1.0MPa. Because this SU model has a magnet (-S), it used CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
