This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X290S, 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 SU50X290S
The AirTAC SU32~50 Standard Cylinder SU50X290S is a double-acting profile-type standard cylinder with a Ø50mm bore and 290mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X290S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X290S
The AirTAC SU50X290S is a discontinued double-acting profile cylinder with a 50mm bore and 290mm stroke. Delivering 982 N push force at 0.5 MPa, it features a 1/4" port and adjustable cushions. AirTAC replaced this unit with the SAU50X290S, a direct replacement matching the exact body, stroke, force, port size, and SC-series mounting footprint.
The SAU upgrade reuses your existing SC-series accessories but switches the sensor family: the SU's legacy CS1-B/DS1-B switches are replaced by modern CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X290S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X290S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU50X290S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×290 | 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 SU50X290S Is Used
Package Diversion
Pushes 50 kg cartons at 90 degrees on a sorting line using a safe 589 N working load.
Pallet Stop Gate
Acts as a 290mm stroke pneumatic stop for pallets, requiring external locking for safety.
Component Ejection
Ejects machined parts from a fixture, utilizing the 982 N push force at 0.5 MPa.
Replacing the Airtac SU32~50 Standard Cylinder SU50X290S with the SAU50X290S
To replace the SU50X290S, order the SAU50X290S. Verify your 1/4" port thread (PT, G, or NPT) and M16x1.5 rod-end connection. Because this unit has the -S magnet, note that your old CS1-B/DS1-B switches must be upgraded to CMSG/DMSG/EMSG sensors. If you need integrated air control, consider the SAUF valve-integrated variant. For loads needing 1374 N at 0.7 MPa, step up to the 63mm bore; if 628 N suffices, the 40mm bore works. At 290mm stroke, mount it rigidly to prevent rod bending and side-load stress. Remember, a standard cylinder drifts without live air; use an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU50X290S
- ✓ 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 SU50X290S FAQ
Yes, the SU50X290S is discontinued. The direct replacement is the SAU50X290S. It matches the 50mm bore, 290mm stroke, 982 N force, 1/4" port, and SC-series mounting. You can swap it directly without changing your mechanical setup.
The 50mm bore provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a 200 kgf max at 1.0 MPa. Because this has the -S magnet, the old CS1-B/DS1-B switches are obsolete; the SAU replacement requires CMSG/DMSG/EMSG sensors.
