This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X25S, 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 SU32X25S
The AirTAC Airtac SU32~50 Standard Cylinder SU32X25S is a double-acting profile-type standard cylinder with a Ø32mm bore and 25mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X25S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X25S
The AirTAC SU32X25S is a discontinued double-acting profile-type cylinder with a 32mm bore and 25mm stroke. Delivering 402N push force at 0.5MPa, it features an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this legacy unit with the SAU32X25S, a direct replacement retaining the exact bore, stroke, output force, 1/8" port, and SC-series mounting.
Because this SKU includes the -S magnet, it originally used legacy CS1-B/DS1-B switches; upgrading to the SAU requires switching to current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF built-in-valve option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X25S 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 SAU32X25S 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 SU32X25S Is Used
Small Part Clamping
Ideal for holding lightweight electronic components during assembly, utilizing the 402N push force at 0.5MPa for secure, non-marring grip.
Package Diverting
Short 25mm stroke provides rapid actuation for routing small cartons on a packaging line without taking up excessive machine footprint.
Ejector Mechanisms
Compact profile body fits easily into dense machinery to push finished molded parts out of a die within a 20kg safe vertical lift range.
Replacing the Airtac SU32~50 Standard Cylinder SU32X25S with the SAU32X25S
To replace the SU32X25S, order the SAU32X25S. Confirm the 1/8" port, M10x1.25 rod thread, and PT/G/NPT thread choice. Since this is an -S model, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If sizing down from a 40mm bore, the 32mm bore yields 402N push at 0.5MPa. A plain cylinder drifts without live air, so use an external rod lock or pilot-operated check valve for held loads. The SAUF valve-integrated variant is an option if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU32X25S
- ✓ 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 SU32X25S FAQ
Yes, the AirTAC SU32X25S is discontinued. The direct replacement is the SAU32X25S, which matches the 32mm bore, 25mm stroke, 402N force, 1/8" port, and SC-series mounting accessories.
The 32mm bore delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. This -S model uses legacy CS1-B/DS1-B sensors, while the SAU replacement uses CMSG/DMSG/EMSG switches.
