This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X350S, 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 SU32X350S
The AirTAC SU32~50 Standard Cylinder SU32X350S is a double-acting profile-type standard cylinder with a Ø32mm bore and 350mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X350S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X350S
The AirTAC SU32X350S is a discontinued double-acting profile-type cylinder with a 32 mm bore and 350 mm stroke. It delivers 402 N push force at 0.5 MPa and features a built-in magnet for legacy CS1-B/DS1-B switches. AirTAC replaced this EOL unit with the SAU32X350S, a direct replacement retaining the exact 1/8" port, M10x1.25 rod thread, 21 mm cushions and SC-series mounting.
The SAU upgrade keeps the compact extruded aluminium body—shorter than an equivalent ISO 15552 cylinder—while modernising the sensor groove to accept current CMSG/DMSG/EMSG switches. Note that the SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the original SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X350S 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 SAU32X350S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×350 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU32X350S Is Used
Compact Part Ejection
Uses the 402 N push force to eject small machined components from a fixture, fitting into tight machine cells where the shorter profile body saves space.
Package Routing Gate
Actuates a diverting gate along a packaging line; the 350 mm stroke provides full travel to reroute boxes without requiring a larger bore cylinder.
Light Tray Indexing
Indexes lightweight storage trays using the 20 kg vertical lift capacity, while the adjustable 21 mm cushions soften the stop at stroke end.
Replacing the Airtac SU32~50 Standard Cylinder SU32X350S with the SAU32X350S
To replace this SU32X350S, order the SAU32X350S. Confirm the 1/8" port, PT/G/NPT thread choice, and your SC-series mounting (LB/FA/FB/CA/CB/TC). Because this SKU has the -S magnet, you must change your sensors: the old CS1-B/DS1-B switches will not fit the SAU, so migrate to CMSG/DMSG/EMSG. For the 350 mm stroke, prevent rod bending by using an external guide to absorb side loads. If you need more force, the neighbouring 40 mm bore provides 628 N push at 0.5 MPa. A plain cylinder drifts without live air, so for load holding add an external rod lock or pilot-operated check valve. The SAUF valve-integrated option is available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU32X350S
- ✓ 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 SU32X350S FAQ
Yes, the SU32X350S is discontinued. The direct replacement is the AirTAC SAU32X350S. It matches the 32 mm bore, 350 mm stroke, 402 N output force, 1/8" port and SC-series mounting. You simply order the SAU equivalent.
The SAU32X350S provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are replaced by the modern CMSG/DMSG/EMSG sensor family on the SAU body.
