This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X320S, 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 SU32X320S
The AirTAC Airtac SU32~50 Standard Cylinder SU32X320S 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 SAU32X320S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X320S
The AirTAC SU32X320S is a discontinued double-acting profile-type cylinder with a 32mm bore and 320mm stroke. It delivers 402N push and 345N pull at 0.5MPa through a 1/8" port. AirTAC replaced this legacy unit with the SAU32X320S direct replacement, matching the exact bore, stroke, output force, port size and SC-series mounting footprint.
The SAU upgrade retains the compact extruded aluminum body but modernizes the sensor groove. Your original -S magnet worked with legacy CS1-B/DS1-B switches, while the SAU uses current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve the SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X320S 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 SAU32X320S 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 SU32X320S Is Used
Package Diverting
Actuates a routing gate for small parcels, relying on the 320mm stroke to clear the main conveyor belt path completely.
Pneumatic Gripper Feed
Advances a material strip 320mm into a stamping press, taking advantage of the compact 32mm profile body to fit tight tooling.
Replacing the Airtac SU32~50 Standard Cylinder SU32X320S with the SAU32X320S
To replace this SU32X320S, order the SAU32X320S. Verify your 1/8" port thread (PT, G, or NPT), M10x1.25 rod end, and SC-series mounting (LB/FA/FB/CA/CB/TC). Because this -S SKU has a magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. For sizing alternatives, a 40mm bore yields 628N push at 0.5MPa, while dropping to 0.7MPa on a 32mm still gives 563N. With a 320mm stroke, prevent rod bending by guiding the load externally to avoid side-load forces. A plain cylinder drifts without live air; the 21mm cushions only decelerate, so use an external rod lock or pilot-operated check valve for load holding. If you need integrated flow control, explore the SAUF valve-cylinder variant.
Replacement checklist
- ✓ Same bore / stroke → SAU32X320S
- ✓ 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 SU32X320S FAQ
Yes, the SU32X320S is discontinued. The direct replacement is the AirTAC SAU32X320S. It shares the identical 32mm bore, 320mm stroke, 1/8" port, output force, and SC-series mounting accessories, so it bolts right in. You simply order the SAU32X320S.
At 0.5MPa it pushes 402N and pulls 345N; at 0.7MPa push is 563N, and the theoretical maximum is 82kgf at 1.0MPa. Because this is an -S model, it has a piston magnet for legacy CS1-B/DS1-B switches. When upgrading to the SAU32X320S, you must switch to the current CMSG/DMSG/EMSG sensor family.
