This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X470S, 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 SU50X470S
The AirTAC SU32~50 Standard Cylinder SU50X470S is a double-acting profile-type standard cylinder with a Ø50mm bore and 470mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X470S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X470S
The AirTAC SU50X470S is a discontinued double-acting profile-type cylinder with a 50mm bore and 470mm stroke. Delivering 982N push force at 0.5MPa, it features an extruded aluminum barrel and adjustable cushions. AirTAC replaced this unit with the SAU50X470S, a direct upgrade retaining the exact bore, stroke, output force, 1/4" port, and SC-series mounting.
The SAU replacement modernizes the sensor groove: your legacy CS1-B/DS1-B switches are superseded by CMSG/DMSG/EMSG sensors. Furthermore, the SAU line introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X470S 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 SAU50X470S 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 SU50X470S Is Used
Long-Stroke Diversion
Pushes packages across transfer lines with a 470mm reach, utilizing the 982N push force at 0.5MPa for reliable routing.
Multi-Stage Ejection
Ejects machined parts from an enclosed workstation, requiring the full 470mm extension to clear the guard doors.
Replacing the Airtac SU32~50 Standard Cylinder SU50X470S with the SAU50X470S
To replace this cylinder, order the SAU50X470S. Verify your 1/4" port thread (PT, G, or NPT) and M16x1.5 rod-end connection. Because this is a 470mm stroke, the Ø20mm rod is susceptible to bending under lateral stress—always use external guides to prevent side-loading. If sizing from scratch, a neighboring 40mm bore yields 628N push at 0.5MPa, while a 63mm bore provides 1559N. Note that a standard cylinder drifts without live air; the cushions only decelerate the stroke. For load holding on air loss, install an external rod lock or pilot-operated check valve. Finally, your -S magnet requires migrating from CS1-B/DS1-B switches to the SAU's CMSG/DMSG/EMSG sensors.
Replacement checklist
- ✓ Same bore / stroke → SAU50X470S
- ✓ 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 SU50X470S FAQ
Yes, the SU50X470S is discontinued. The direct replacement is the AirTAC SAU50X470S. It shares the identical 50mm bore, 470mm stroke, output force, 1/4" port, and SC-series mounting, but requires CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
The 1/4" port (fixed by the 50mm bore) feeds a piston generating 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, 1767N at 0.9MPa, and a 200kgf maximum at 1.0MPa. The 470mm stroke operates at 30-800mm/s with 21mm adjustable cushions at both ends.
