This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X330, 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 SU32X330
The AirTAC Airtac SU32~50 Standard Cylinder SU32X330 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 SAU32X330, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X330
The AirTAC SU32X330 is a discontinued double-acting profile-type cylinder with a 32 mm bore and 330 mm stroke. It delivers 402 N push force at 0.5 MPa. AirTAC replaced this unit with the SAU32X330 direct replacement, matching the original bore, stroke, output force, 1/8" port, and SC-series mounting accessories exactly.
Because this 330 mm stroke is relatively long for a 12 mm rod, use external guides to prevent side-load bending. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore. Note that this SKU lacks a magnet and cannot accept a sensor; the SAU upgrade uses CMSG/DMSG/EMSG switches and adds a SAUF valve-integrated option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X330 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 SAU32X330 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 SU32X330 Is Used
Package Diverting
Sort light cartons on a packaging line where the 402 N push force at 0.5 MPa easily deflects items onto auxiliary tracks.
Small Part Ejection
Push molded or machined components out of a fixture, utilizing the 330 mm stroke to clear the work area completely.
Replacing the Airtac SU32~50 Standard Cylinder SU32X330 with the SAU32X330
To replace the SU32X330, order the SAU32X330 direct equivalent. Verify your 1/8" port thread (PT, G, or NPT) and SC-series mounting (LB, FA, FB, CA, CB, TC). Since this is a non-magnetized SKU, it cannot accept position sensors; if you need sensing on the SAU, specify the -S option and migrate from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. With the 330 mm stroke, external guides are essential to prevent rod bending. The cylinder will not hold a load on air loss—use an external rod lock or pilot-operated check valve. For faster actuation, the SAUF variant integrates a 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU32X330
- ✓ 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 SU32X330 FAQ
Yes, the SU32X330 is discontinued. The direct replacement is the AirTAC SAU32X330. It shares the same 32 mm bore, 330 mm stroke, 1/8" port, and SC-series mounting, so it fits the same application without mechanical modifications.
At 0.5 MPa it pushes 402 N and pulls 345 N; at 0.7 MPa it pushes 563 N, with a theoretical max of 82 kgf at 1.0 MPa. This specific SKU has no magnet and cannot take a sensor. If sensing is needed on the SAU replacement, add the -S option and use CMSG/DMSG/EMSG switches.
