This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X380S, 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 SU32X380S
The AirTAC SU32~50 Standard Cylinder SU32X380S is a double-acting profile-type standard cylinder with a Ø32mm bore and 380mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X380S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X380S
The AirTAC SU32X380S is a discontinued double-acting profile-type cylinder with a 32mm bore and 380mm stroke. It delivers 402N push and 345N pull at 0.5MPa, featuring a 1/8" port and an M10x1.25 rod thread. AirTAC replaced this legacy unit with the SAU32X380S, a direct replacement retaining the exact bore, stroke, output force, port size and SC-series mounting.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors, replacing the older CS1-B/DS1-B switches used on this -S model, and adds an optional SAUF valve-integrated variant. The extruded aluminium profile is more compact than a same-bore ISO 15552 unit.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X380S 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 SAU32X380S 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 SU32X380S Is Used
Small Parts Ejection
Uses the 402N push force at 0.5MPa to eject light machined components from a fixture, with the 380mm stroke clearing the work area completely.
Package Diverting
Extends across a belt to deflect small cartons, relying on the compact 32mm profile to fit within tight transfer station side frames.
Light Tray Sorting
Handles the 20kg vertical lift margin to index loaded trays downward, requiring external guide rails to support the long 380mm rod extension.
Replacing the Airtac SU32~50 Standard Cylinder SU32X380S with the SAU32X380S
To replace the SU32X380S, order the SAU32X380S. Confirm the 1/8" port, M10x1.25 rod thread, PT/G/NPT thread standard, and SC-series mounting (LB/FA/FB/CA/CB) are retained. Because this has a 380mm stroke, use external guides to prevent rod bending and side-load wear. The -S magnet means you must switch from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. If stepping up to a 40mm bore, push force at 0.5MPa rises to 628N; dropping to a 25mm stroke reduces footprint. The cylinder does not hold load without live air; add an external rod lock or pilot-operated check valve for safety, and consider the SAUF variant if you need a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU32X380S
- ✓ 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 SU32X380S FAQ
Yes, the SU32X380S is discontinued. The direct replacement is the AirTAC SAU32X380S. It matches the 32mm bore, 380mm stroke, 1/8" port, output force and SC-series mounting, so it fits the same application without mechanical changes.
The SAU32X380S provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. Because your SU model has a magnet (-S), you must upgrade from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family on the SAU.
