This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X340, 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 SU50X340
The AirTAC Airtac SU32~50 Standard Cylinder SU50X340 is a double-acting profile-type standard cylinder with a Ø50mm bore and 340mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X340, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X340
The AirTAC SU50X340 is a discontinued double-acting profile-type cylinder with a 50mm bore and 340mm stroke. It delivers 982 N push force at 0.5 MPa via a 1/4" port. AirTAC replaced this unit with the SAU50X340, a direct upgrade retaining the exact bore, stroke, output force, and SC-series mounting footprint.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors, replacing the SU's legacy CS1-B/DS1-B switches, and offers a new SAUF variant with a built-in 4M solenoid valve. Note this specific SKU lacks a magnet (-S) and cannot accept sensing switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X340 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 SAU50X340 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). |
|---|---|
| 50 | Bore size in mm. |
| ×340 | 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 SU50X340 Is Used
Pallet Stopper Gate
Acts as a pneumatic stop for incoming pallets, absorbing kinetic energy through adjustable 21mm cushions at both ends.
Component Ejection
Ejects machined parts from a fixture, using the compact extruded profile to save space in tight cell layouts.
Replacing the Airtac SU32~50 Standard Cylinder SU50X340 with the SAU50X340
To replace this discontinued SU50X340, order the SAU50X340. Confirm the 1/4" port, M16x1.5 rod thread, and PT/G/NPT thread preference. Because this is a non-magnet SKU, it cannot support sensors; if detection is needed, specify an SAU50X340-S and migrate to CMSG/DMSG/EMSG switches. The 340mm stroke exceeds 300mm, so use external guides to prevent rod bending under side loads. If comparing neighbours, the 40mm bore yields 628 N push while the 63mm bore yields 1559 N. For load holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. Alternatively, evaluate the SAUF50X340 for integrated valve control.
Replacement checklist
- ✓ Same bore / stroke → SAU50X340
- ✓ 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 SU50X340 FAQ
Yes, the SU50X340 is discontinued. The direct replacement is the AirTAC SAU50X340. It matches the 50mm bore, 340mm stroke, 1/4" port, output force, and SC-series mounting accessories, fitting the same application directly.
It delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a 200 kgf maximum at 1.0 MPa. This specific SKU lacks a magnet, so it cannot take sensors; the SAU-S replacement uses CMSG/DMSG/EMSG switches.
