This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X400, 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 SU32X400
The AirTAC Airtac SU32~50 Standard Cylinder SU32X400 is a double-acting profile-type standard cylinder with a Ø32mm bore and 400mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X400, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X400
The AirTAC SU32X400 is a discontinued double-acting profile-type cylinder with a 32 mm bore and 400 mm stroke. It delivers 402 N push force at 0.5 MPa and features a 1/8" port. AirTAC replaced this end-of-line unit with the SAU32X400, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting accessories.
The SAU upgrade uses current CMSG/DMSG/EMSG sensors, whereas this legacy SU had no magnet and cannot accept a switch. The SAU family also adds a SAUF built-in 4M valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X400 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 SAU32X400 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 SU32X400 Is Used
Bin Push-Off
Ejects small totes from storage racks, leveraging the compact 32 mm profile body to fit tight vertical shelving clearances.
Parts Ejection
Clears small machined components from a fixture, using adjustable 21 mm cushions to decelerate the rod at stroke end.
Replacing the Airtac SU32~50 Standard Cylinder SU32X400 with the SAU32X400
To replace the SU32X400, order the SAU32X400. Verify your 1/8" port, M10x1.25 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU lacks a magnet (-S), it cannot take a sensor; if you need position detection on the SAU, order the -S version and use CMSG/DMSG/EMSG switches. For loads needing 563 N push at 0.7 MPa, step up to a 40 mm bore; if 241 N suffices, a 32 mm works. A plain cylinder drifts on air loss—the 21 mm cushions only decelerate, so use an external rod lock for holding. The 400 mm stroke requires external guides to prevent rod bending under side loads. The SAUF valve-integrated variant is available if you want self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU32X400
- ✓ 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 SU32X400 FAQ
Yes, the SU32X400 is discontinued. The direct replacement is the SAU32X400, which shares the same 32 mm bore, 400 mm stroke, force, 1/8" port, and SC-series mounting.
It delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot accept a sensor; the SAU -S variant uses CMSG/DMSG/EMSG switches.
