This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X330S, 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 SU32X330S
The AirTAC Airtac SU32~50 Standard Cylinder SU32X330S is a double-acting profile-type standard cylinder with a Ø32mm bore and 330mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X330S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X330S
The AirTAC SU32X330S is a discontinued double-acting profile-type cylinder with a 32mm bore and 330mm stroke. Delivering 402N push force at 0.5MPa, its extruded aluminium body is more compact than an ISO 15552 unit of the same bore. AirTAC replaced it with the SAU32X330S, a direct equivalent sharing the exact bore, stroke, 1/8" port, and SC-series mounting.
Two upgrade facts: the SAU replacement switches to current CMSG/DMSG/EMSG sensors from the SU's legacy CS1-B/DS1-B switches, and the SAU line adds a SAUF built-in 4M solenoid valve option the SU never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X330S 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 SAU32X330S 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 SU32X330S Is Used
Small Parts Ejection
Uses the 402N push force at 0.5MPa to eject light machined components from a fixture, with the 330mm stroke clearing the workspace safely.
Package Diverting
Actuates a routing gate on a packaging line, where the compact profile body saves space and the 1/8" port delivers rapid 30-800mm/s cycling.
Replacing the Airtac SU32~50 Standard Cylinder SU32X330S with the SAU32X330S
To replace this SU32X330S with the SAU32X330S, confirm the 32mm bore, 330mm stroke, 1/8" port, and M10x1.25 rod thread. Specify your port thread (PT/G/NPT) and SC-series mounting (LB/FA/FB/CA/CB/TC). Because this SKU has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG on the SAU. If sizing alternatives, the neighbouring 40mm bore yields 628N push at 0.5MPa. At 330mm, prevent rod bending by using an external guide to absorb side loads. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the 21mm cushions only decelerate. The SAUF valve-integrated variant is available if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU32X330S
- ✓ 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 SU32X330S FAQ
Yes, the AirTAC SU32X330S is discontinued. The direct replacement is the SAU32X330S. It shares the identical 32mm bore, 330mm stroke, output force, 1/8" port, and SC-series mounting accessories, so it fits the same application directly.
The SAU32X330S matches the SU forces: 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and an 82kgf max at 1.0MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are replaced by current CMSG/DMSG/EMSG sensors on the SAU.
