This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X625, 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 SU50X625
The AirTAC Airtac SU32~50 Standard Cylinder SU50X625 is a double-acting profile-type standard cylinder with a Ø50mm bore and 625mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X625, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X625
The AirTAC SU50X625 is a discontinued double-acting profile-type cylinder with a 50mm bore and 625mm stroke. It delivers 982 N of push force at 0.5 MPa through a 1/4" port. AirTAC replaced this legacy unit with the SAU50X625, a direct alternative retaining the exact bore, stroke, force, port size, and SC-series mounting footprint.
When upgrading to the SAU50X625, your body dimensions and 1/4" pneumatic connections remain unchanged. The SAU platform introduces current CMSG/DMSG/EMSG sensors, replacing the older CS1-B/DS1-B switches used on the SU line, and adds a new SAUF variant with a built-in 4M solenoid valve. Note that this specific SKU lacks a magnet and cannot support sensing.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X625 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 SAU50X625 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 SU50X625 Is Used
Long-Stroke Diversion
Pushes packages across a 625mm transfer lane with a safe 589N working load, utilizing the compact profile body to save space along the conveyor frame.
Vertical Material Lift
Raises lightweight totes up to 50kg through a 625mm vertical stroke, requiring external linear guides to prevent rod deflection during elevation.
Component Ejection
Ejects machined parts from an enclosed workstation, taking advantage of the 982N thrust at 0.5MPa and adjustable end cushions to stop smoothly.
Replacing the Airtac SU32~50 Standard Cylinder SU50X625 with the SAU50X625
To replace the SU50X625, order the SAU50X625 direct equivalent, verifying your 1/4" port threads (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, or TC). Because this 625mm stroke exceeds 300mm, you must support the load with external guides to prevent rod bending and premature seal wear from side loads. Sizing alternatives: the neighboring 40mm bore provides 628 N push at 0.5 MPa, while the 63mm bore offers 1559 N. This non-magnetic SKU cannot accept a sensor; if position detection is needed, specify an SAU50X625S and migrate to CMSG/DMSG/EMSG switches. A standard cylinder drifts on air loss—the cushion only decelerates—so install an external rod lock or pilot-operated check valve for load holding. The SAUF valve-integrated option can simplify cycle control.
Replacement checklist
- ✓ Same bore / stroke → SAU50X625
- ✓ 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 SU50X625 FAQ
Yes, the SU50X625 is discontinued. The direct replacement is the AirTAC SAU50X625. It shares the identical 50mm bore, 625mm stroke, 982N force at 0.5MPa, 1/4" port, and SC-series mounting, so it drops directly into your existing machine.
At 0.5 MPa it provides 982 N push and 825 N pull; at 0.7 MPa it pushes 1374 N, with a theoretical max of 200 kgf at 1.0 MPa. This specific SKU has no magnet and cannot accept a sensor. If you need sensing, order the SAU50X625S and use current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
