This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X320, 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 SU32X320
The AirTAC SU32~50 Standard Cylinder SU32X320 is a double-acting profile-type standard cylinder with a Ø32mm bore and 320mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X320, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X320
The AirTAC SU32X320 is a discontinued double-acting profile-type cylinder with a 32mm bore and 320mm stroke. Delivering 402N push force at 0.5MPa via a 1/8" port, its extruded aluminum body is more compact than an ISO 15552 unit. The direct replacement is the SAU32X320, matching bore, stroke, force, port and SC-series mounts.
Because this SKU lacks a magnet (-S), it cannot accept sensors; the SAU upgrade adds modern CMSG/DMSG/EMSG switch compatibility and a new SAUF built-in valve option. Note that air cushions only decelerate, so use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X320 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 SAU32X320 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 SU32X320 Is Used
Small Part Ejection
Pushes lightweight plastic or stamped metal components out of press beds and machining centers into collection bins using a compact 32mm profile body.
Pneumatic Gate Actuation
Operates small access doors and safety guards on automated machinery, benefiting from the shorter body profile compared to standard ISO cylinders.
Replacing the Airtac SU32~50 Standard Cylinder SU32X320 with the SAU32X320
To replace this SU32X320, order the SAU32X320, confirming the 32mm bore, 320mm stroke, 1/8" port, M10x1.25 rod thread and SC-series mounting. Since this is a non-magnet SKU, it cannot take a sensor, but if you need position detection on the SAU, specify the -S option to use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For higher loads, neighbouring bores like the 40mm offer 628N push at 0.5MPa. At 320mm stroke, prevent rod bending by guiding the load externally. Finally, a plain cylinder drifts on air loss, so fit a pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU32X320
- ✓ 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 SU32X320 FAQ
Yes, the AirTAC SU32X320 is discontinued and end-of-life. The direct replacement is the SAU32X320. It provides identical 32mm bore, 320mm stroke, 402N push force at 0.5MPa, 1/8" port size, and uses the same SC-series mounting accessories, fitting the same application envelope.
At 0.5MPa it provides 402N push and 345N pull, 563N push at 0.7MPa, 724N at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa. This specific SKU has no magnet, so it cannot accept magnetic sensors; upgrading to a SAU32X320-S allows the use of current CMSG/DMSG/EMSG switches.
