This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X155S, 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 SU32X155S
The AirTAC Airtac SU32~50 Standard Cylinder SU32X155S is a double-acting profile-type standard cylinder with a Ø32mm bore and 155mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X155S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X155S
The AirTAC SU32X155S is a discontinued double-acting profile-type cylinder with a 32mm bore and 155mm stroke. Because 155mm is not a standard stroke, it was supplied as a non-standard length. It delivers 402N push and 345N pull at 0.5MPa through a 1/8" port. AirTAC replaced this EOL unit with the SAU32X155S, a direct replacement retaining the exact bore, stroke, force, port size, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace this model's legacy CS1-B/DS1-B switches, and adds an optional SAUF built-in 4M valve. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore. Note that a plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X155S 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 SAU32X155S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×155 | Stroke length in mm. |
| -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 SU32X155S Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to eject small machined components from a fixture without damaging the surface.
Package Diverting
Actuates a lightweight routing gate on a packaging line, where the 20kg vertical lift capacity easily moves the mechanism.
Bin Push-Off
Pushes small totes from a gravity conveyor using the compact 32mm profile body to fit within tight machine clearances.
Replacing the Airtac SU32~50 Standard Cylinder SU32X155S with the SAU32X155S
To replace this discontinued SU32X155S, order the SAU32X155S direct equivalent. Verify your 1/8" port thread (PT/G/NPT), M10x1.25 rod-end, and SC-series mounting (LB/FA/FB/CA/CB/TC). Because this has an -S magnet, you must upgrade your legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. For sizing both ways: a 40mm bore offers 628N push at 0.5MPa if you need more force, while dropping to 0.3MPa yields about 241N. The 155mm stroke is non-standard; at lengths over 100mm, ensure guide rails prevent rod bending under side loads. This cylinder does not hold load without live air; add a pilot-operated check valve if needed. The SAUF variant integrates a valve for self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU32X155S
- ✓ 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 SU32X155S FAQ
Yes, the SU32X155S is discontinued. The direct replacement is the AirTAC SAU32X155S. It shares the same 32mm bore, 155mm stroke, 402N force, 1/8" port, and SC-series mounting, but requires upgrading your CS1-B/DS1-B sensors to the CMSG/DMSG/EMSG family.
The 32mm bore uses a 1/8" port. It generates 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa.
