This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X50S, 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 SU50X50S
The AirTAC SU32~50 Standard Cylinder SU50X50S is a double-acting profile-type standard cylinder with a Ø50mm bore and 50mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X50S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X50S
The AirTAC SU50X50S is a discontinued double-acting profile-type cylinder with a 50mm bore and 50mm stroke, delivering 982 N of push force at 0.5 MPa. Its extruded aluminum barrel makes it more compact than an ISO 15552 cylinder of the same bore, while retaining SC-series mounting compatibility. AirTAC replaced this unit with the SAU50X50S, a direct upgrade matching the exact bore, stroke, output force, 1/4" port, and M16x1.5 rod thread.
When migrating to the SAU50X50S, your SC-series accessories transfer directly, but the sensor family changes: this legacy SU50X50S used CS1-B/DS1-B switches, whereas the SAU requires current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered.

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 SAU50X50S 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 SU50X50S Is Used
Package Diverting
Actuates a routing gate on a packaging line, where the 50 kg vertical lift capacity and 50mm stroke provide rapid, precise redirection of boxes.
Pallet Stopper Arm
Deploys a stopping lug in a pallet flow system, leveraging the extruded profile body to save space while handling 982 N of push force at 0.5 MPa.
Replacing the Airtac SU32~50 Standard Cylinder SU50X50S with the SAU50X50S
To replace the SU50X50S, order the SAU50X50S and verify your 1/4" port thread (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, or TC). Because this SKU includes a magnet, you must account for the sensor transition: the legacy CS1-B/DS1-B switches will not fit the SAU, so budget for CMSG/DMSG/EMSG sensors. If your application needs self-switching, consider the SAUF50X50S with its integrated valve. For sizing alternatives, dropping to a 40mm bore reduces push force to 628 N at 0.5 MPa, while stepping up to a 63mm bore increases it to 1559 N. Remember that a standard cylinder does not hold load without live air; the 21mm adjustable cushions only decelerate near stroke end, so add an external rod lock or pilot-operated check valve for secure vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAU50X50S
- ✓ 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 SU50X50S FAQ
Yes, the SU50X50S is discontinued. The direct replacement is the AirTAC SAU50X50S. It matches the 50mm bore, 50mm stroke, 982 N force at 0.5 MPa, 1/4" port, and SC-series mounting. The only change is that your legacy CS1-B/DS1-B sensors must be upgraded to CMSG/DMSG/EMSG sensors.
The 50mm bore features a 1/4" air port and a 20mm piston rod. At 0.5 MPa it provides 982 N push and 825 N pull force. At 0.7 MPa push is 1374 N, and at 0.9 MPa it is 1767 N. The theoretical maximum force is 200 kgf at 1.0 MPa, with adjustable cushions of 21mm at both ends.
