This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X30, 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 SU32X30
The AirTAC Airtac SU32~50 Standard Cylinder SU32X30 is a double-acting profile-type standard cylinder with a Ø32mm bore and 30mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X30, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X30
The AirTAC SU32X30 is a discontinued double-acting profile-type cylinder with a 32mm bore and 30mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore, delivering 402 N of push force at 0.5 MPa through a 1/8" port. AirTAC replaced this unit with the SAU32X30, a direct upgrade sharing the exact same body dimensions, force, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU32X30 upgrade also adds the SAUF built-in-valve option the SU line never had, and uses modern CMSG/DMSG/EMSG switches if you ever need sensing.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X30 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X30 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 SU32X30 Is Used
Clamp Actuation
Provides reliable clamping force for small assembly jigs where a compact 32mm profile body is required to fit tight spaces.
Replacing the Airtac SU32~50 Standard Cylinder SU32X30 with the SAU32X30
To replace this discontinued SU32X30, order the SAU32X30 direct equivalent, confirming the 32mm bore, 30mm stroke, 1/8" port, and M10x1.25 rod thread. Specify your seal (default TPU, or Viton H for 0-150 C high-temp) and mounting (SC-series LB/FA/FB/CA/CB). Since this specific SKU has no magnet (-S), it cannot accept a sensor; if you require position detection on the SAU replacement, add the -S option and note that switches change from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG family. For higher force needs, step up to the 40mm bore (628 N push @0.5 MPa), or drop to a smaller bore if 402 N is excessive. Remember, a plain cylinder drifts on air loss—the 21mm adjustable cushion only decelerates near stroke end, so use an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU32X30
- ✓ 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 SU32X30 FAQ
Yes, the AirTAC SU32X30 is discontinued and end-of-life. The direct replacement is the SAU32X30. It shares the identical 32mm bore, 30mm stroke, 402 N output force, 1/8" port, and SC-series mounting accessories, so it fits the same application without modification.
At 0.5 MPa it pushes 402 N and pulls 345 N; at 0.7 MPa it pushes 563 N, and the theoretical maximum is 82 kgf at 1.0 MPa. Because this particular SKU lacks a magnet, it cannot take a sensor. If you need sensing on the SAU replacement, the modern CMSG/DMSG/EMSG switches are required instead of the legacy CS1-B/DS1-B.
