This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X605S, 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 SU40X605S
The AirTAC SU32~50 Standard Cylinder SU40X605S is a double-acting profile-type standard cylinder with a Ø40mm bore and 605mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X605S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X605S
The AirTAC SU40X605S is a discontinued double-acting profile-type cylinder with a 40mm bore and 605mm stroke. AirTAC ended this line, replacing it with the SAU40X605S direct equivalent featuring the same 1/4 inch port, M12x1.25 rod thread, and SC-series mounting.
Upgrading to the SAU keeps the exact profile body, bore, stroke, and force, but changes the sensor family: this SU's -S magnet used legacy CS1-B/DS1-B switches, whereas the SAU requires current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line never offered. Because the 605mm stroke is long, prevent rod bending by guiding the load externally.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X605S 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 SAU40X605S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 40 | Bore size in mm. |
| ×605 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU40X605S Is Used
Package Diverting
Pushes cartons on a 40mm bore line using 628N push force at 0.5MPa, diverting lightweight goods across a 605mm transfer gap.
Component Ejection
Ejects machined parts from a fixture using 528N pull force, cycling at 30-800mm/s with adjustable 21mm cushions.
Replacing the Airtac SU32~50 Standard Cylinder SU40X605S with the SAU40X605S
To replace this discontinued SU40X605S, order the SAU40X605S direct equivalent, verifying your 1/4 inch port thread (PT/G/NPT) and SC-series mounting accessories like LB or FA. If your application relied on the -S magnet, note that the SAU uses CMSG/DMSG/EMSG switches instead of the older CS1-B/DS1-B. For sizing alternatives, a 32mm bore yields 402N push at 0.5MPa, while a 50mm bore provides 982N; this 40mm bore gives 628N. A plain cylinder drifts without live air since the cushions only decelerate, so use an external rod lock or pilot-operated check valve for held loads. With the 605mm stroke, add external guides to prevent side-load rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU40X605S
- ✓ 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 SU40X605S FAQ
Yes, the AirTAC SU40X605S is discontinued. The direct replacement is the SAU40X605S. It shares the same 40mm bore, 605mm stroke, 628N force, 1/4 inch port, and SC-series mounting, so it fits the same application.
At 0.5MPa it provides 628N push and 528N pull, 879N push at 0.7MPa, and a 128kgf max at 1.0MPa. The -S magnet on this SU worked with legacy CS1-B/DS1-B switches; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
