This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X925S, 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 SU32X925S
The AirTAC SU32~50 Standard Cylinder SU32X925S is a double-acting profile-type standard cylinder with a Ø32mm bore and 925mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X925S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X925S
The AirTAC SU32X925S is a discontinued double-acting profile cylinder with a 32mm bore and 925mm stroke. Delivering 402 N push at 0.5 MPa, it uses a 1/8" port and M10x1.25 rod thread. AirTAC replaced this legacy unit with the SAU32X925S, a direct upgrade sharing the exact bore, stroke, output force, port size, and SC-series mounting accessories.
Because this SKU includes a magnet (-S), it originally used CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors. The SAU family also adds a SAUF built-in 4M valve option the SU line lacked. Note that standard cushions only decelerate; they do not hold load without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X925S 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 SAU32X925S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×925 | 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 SU32X925S Is Used
Long-Reach Diverting
Pushes light packages across a transfer lane using the 925mm stroke, relying on external guides to prevent rod bending during the extended travel.
Compact Assembly Ejector
Ejects finished parts from a tight machine cell where the shorter profile body saves space compared to standard ISO 15552 cylinders of the same bore.
Replacing the Airtac SU32~50 Standard Cylinder SU32X925S with the SAU32X925S
To replace this discontinued SU32X925S, order the SAU32X925S direct equivalent, verifying your 1/8" port, M10x1.25 rod, and SC-series mounting (LB/FA/FB/CA/CB). If your machine relied on the -S magnet, you must upgrade sensors from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. For load holding without live air, add an external rod lock or pilot-operated check valve, as cushions only decelerate. With a 925mm stroke, prevent rod bending by guiding the load externally to avoid side-load damage. If you need more force, the 40mm bore offers 628 N push at 0.5 MPa; if less is acceptable, dropping to a smaller bore reduces footprint. The SAUF variant integrates a valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU32X925S
- ✓ 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 SU32X925S FAQ
Yes, the SU32X925S is discontinued. The direct replacement is the SAU32X925S, which shares the identical 32mm bore, 925mm stroke, 1/8" port, output force, and SC-series mounting. You can swap it directly without modifying your machine.
At 0.5 MPa it provides 402 N push and 345 N pull; 563 N push at 0.7 MPa; 724 N at 0.9 MPa; and a theoretical max of 82 kgf at 1.0 MPa. Because this is the -S magnet version, it used legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
