This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X437S, 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 SU32X437S
The AirTAC SU32~50 Standard Cylinder SU32X437S is a double-acting profile-type standard cylinder with a Ø32mm bore and 437mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X437S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X437S
The AirTAC SU32X437S is a discontinued double-acting profile-type cylinder with a 32mm bore and 437mm stroke. It delivered 402N push and 345N pull at 0.5MPa through a 1/8" port. AirTAC replaced this end-of-line unit with the SAU32X437S, a direct alternative retaining the exact bore, stroke, force, port, and SC-series mounting footprint.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace this model's legacy CS1-B/DS1-B switches, and it offers the new SAUF built-in 4M valve option the SU line lacked. Note that 437mm is a nonstandard stroke exceeding the 32mm bore's 1000mm max standard limit.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X437S 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 SAU32X437S 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 SU32X437S Is Used
Small Parts Ejection
Uses the 402N push force at 0.5MPa to eject light molded components from a press bed over the 437mm travel distance.
Package Diverting
Actuates a routing gate on a packaging line, where the compact profile body saves space compared to standard ISO cylinders.
Light Tray Handling
Moves goods trays up to the 20kg vertical lift limit, requiring external guides to manage the 437mm stroke safely.
Replacing the Airtac SU32~50 Standard Cylinder SU32X437S with the SAU32X437S
To replace this discontinued SU32X437S, order the SAU32X437S, confirming the 32mm bore, 437mm stroke, 1/8" port, M10x1.25 rod thread, and SC-series mounts. Because the -S magnet is present, you must migrate from legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG family. For loads needing 563N at 0.7MPa, step up to a 40mm bore; for lighter tasks, a 25mm class may suffice. A plain cylinder drifts without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for held loads. With this 437mm stroke, use external guides to prevent rod bending under side loads. The SAUF variant adds a self-switching valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU32X437S
- ✓ 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 SU32X437S FAQ
Yes, the SU32X437S is discontinued. The direct replacement is the SAU32X437S. It matches the 32mm bore, 437mm stroke, 402N force, 1/8" port, and SC-series mounting accessories, but requires upgrading from CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches.
At 0.5MPa it provides 402N push and 345N pull, increasing to 563N at 0.7MPa, with a theoretical max of 82kgf at 1.0MPa. It operates at 30-800mm/s, uses a 1/8" port with an M10x1.25 rod thread, and has 21mm adjustable cushions at both ends.
