This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X400S, 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 SU32X400S
The AirTAC SU32~50 Standard Cylinder SU32X400S 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 SAU32X400S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X400S
The AirTAC SU32X400S is a discontinued double-acting profile-type cylinder with a 32mm bore and 400mm stroke. It delivers 402N push and 345N pull at 0.5MPa via a 1/8 port. The direct replacement is the SAU32X400S, matching the bore, stroke, force, port and SC-series mounting exactly.
The SAU upgrade adopts CMSG/DMSG/EMSG sensors instead of this legacy CS1-B/DS1-B hardware, and introduces the SAUF built-in-valve variant. The extruded aluminum body is more compact than an ISO 15552 unit of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X400S 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 SAU32X400S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU32X400S Is Used
Small Part Ejection
Ejects machined small parts from a press area, relying on the 345N pull force to retract the 12mm rod quickly.
Component Sorting
Actuates a sorting gate for small electronic components, benefiting from the compact 32mm profile body and adjustable cushions.
Replacing the Airtac SU32~50 Standard Cylinder SU32X400S with the SAU32X400S
To replace this SU32X400S, order the SAU32X400S. Verify your 1/8 port thread (PT/G/NPT), M10x1.25 rod end, and SC-series mounts (LB/FA/FB/CA/CB/TC). Because this SKU has the -S magnet, you must switch to CMSG/DMSG/EMSG switches; a no-S cylinder cannot take a sensor. For the 400mm stroke, use an external guide to prevent rod bending under side loads. If stepping up to a 40mm bore, push force rises to 628N at 0.5MPa. Note that the air cushion only decelerates; use a pilot-operated check valve or rod lock to hold loads, and consider the SAUF variant for integrated valve control.
Replacement checklist
- ✓ Same bore / stroke → SAU32X400S
- ✓ 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 SU32X400S FAQ
Yes, the SU32X400S is discontinued. The direct replacement is the SAU32X400S. It matches the 32mm bore, 400mm stroke, 1/8 port, output force, and SC-series mounting accessories. You simply order the SAU equivalent.
At 0.5MPa it pushes 402N and pulls 345N; at 0.7MPa push is 563N, with a theoretical max of 82kgf at 1.0MPa. Because this is an -S model with a magnet, it used legacy CS1-B/DS1-B switches. The SAU32X400S replacement requires the current CMSG/DMSG/EMSG sensor family.
