This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X750S, 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 SU32X750S
The AirTAC SU32~50 Standard Cylinder SU32X750S is a double-acting profile-type standard cylinder with a Ø32mm bore and 750mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X750S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X750S
The AirTAC SU32X750S is a discontinued double-acting profile-type cylinder with a 32mm bore and 750mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. AirTAC replaced this legacy unit with the SAU32X750S, a direct sharing the exact bore, stroke, force, port and SC-series mounting.
The SAU upgrade switches the -S magnet to current CMSG/DMSG/EMSG sensors (retiring the old CS1-B/DS1-B) and adds an optional SAUF built-in valve. Note that standard cushions only decelerate; use an external rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X750S 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 SAU32X750S 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. |
| ×750 | 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.

Compact Assembly Ejector
Ejects machined parts along a 750mm axis where the extruded profile body saves space over standard ISO cylinders.
Replacing the Airtac SU32~50 Standard Cylinder SU32X750S with the SAU32X750S
To replace this SU32X750S, order the SAU32X750S direct equivalent, verifying the 32mm bore, 750mm stroke, 1/8" port, M10x1.25 rod thread and SC-series mounting. Because the -S magnet is present, prepare to swap legacy CS1-B/DS1-B switches for SAU-compatible CMSG/DMSG/EMSG sensors. For load holding, add a pilot-operated check valve or rod lock, as cushions only decelerate. At 750mm, prevent side-load rod bending with an external guide. If downsizing, a 40mm bore yields 628N push at 0.5MPa; if upsizing, 50mm gives 982N. The SAUF valve-integrated variant is available if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU32X750S
- ✓ 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 SU32X750S FAQ
Yes, the SU32X750S is discontinued. The direct replacement is the AirTAC SAU32X750S, which shares the identical 32mm bore, 750mm stroke, 402N force, 1/8" port and SC-series mounting. You simply order the SAU equivalent.
The 32mm bore provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a max of 82kgf at 1.0MPa. Because your SU has an -S magnet, note the SAU replacement requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
