This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X25FA, 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 SU32X25FA
The AirTAC Airtac SU32~50 Standard Cylinder SU32X25FA 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 SAU32X25FA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X25FA
The AirTAC SU32X25FA is a discontinued double-acting profile cylinder featuring a 32mm bore and 25mm stroke with an FA front mounting interface. It delivers 402N push force at 0.5MPa. AirTAC replaced this unit with the SAU32X25FA, a direct alternative retaining the exact body, force, 1/8" port, and SC-series mounting.
Because this is a compact extruded-aluminium profile body, it is shorter than an ISO 15552 cylinder of the same bore. Note that this no-magnet SKU cannot accept a sensor; the SAU upgrade uses CMSG/DMSG/EMSG switches for -S versions and adds a SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X25FA 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 SAU32X25FA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×25 | 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 SU32X25FA Is Used
Small Part Clamping
Ideal for holding light 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 diverting small cartons on a packaging line without occupying excessive machine footprint.
Replacing the Airtac SU32~50 Standard Cylinder SU32X25FA with the SAU32X25FA
To replace the SU32X25FA, order the SAU32X25FA, confirming the 32mm bore, 25mm stroke, 1/8" port, M10x1.25 rod thread, and FA mounting. This no-magnet SKU cannot accept a sensor; if sensing is needed, specify an -S SAU and migrate to CMSG/DMSG/EMSG switches (the SU used CS1-B/DS1-B). For higher loads, the 40mm bore yields 628N push at 0.5MPa. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock for holding. The SAUF valve-integrated variant is available if desired.
Replacement checklist
- ✓ Same bore / stroke → SAU32X25FA
- ✓ 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 SU32X25FA FAQ
Yes, the AirTAC SU32X25FA is discontinued. The direct replacement is the SAU32X25FA, which shares the same 32mm bore, 25mm stroke, 1/8" port, FA mount, and output force.
It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. This specific SKU lacks a magnet, so it cannot accept a sensor; the SAU -S variant uses CMSG/DMSG/EMSG switches.
