This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X1200S, 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 SU32X1200S
The AirTAC SU32~50 Standard Cylinder SU32X1200S is a double-acting profile-type standard cylinder with a Ø32mm bore and 1200mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X1200S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X1200S
The AirTAC SU32X1200S is a discontinued double-acting profile-type cylinder with a 32mm bore and 1200mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. The direct replacement is the SAU32X1200S, matching the bore, stroke, force, port, and SC-series mounting. Note that 1200mm exceeds the 1000mm standard stroke limit for this bore, making it a non-standard, made-to-order length.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace this unit's legacy CS1-B/DS1-B switches, and offers a SAUF valve-integrated option the SU line lacked. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X1200S 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 SAU32X1200S 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 SU32X1200S Is Used
High-Bay Ejection
Ejects small totes from tall storage racks where a compact 32mm profile body is required to fit within tight vertical machinery clearances.
Linear Part Feeding
Feeds components along an extended assembly line track, relying on external guide rails to support the piston rod over the 1200mm extension.
Replacing the Airtac SU32~50 Standard Cylinder SU32X1200S with the SAU32X1200S
To replace this SU32X1200S, order the SAU32X1200S direct equivalent, verifying the 1/8" port, M10x1.25 rod thread, and SC-series mounting. Because the 1200mm stroke exceeds the 1000mm standard maximum for a 32mm bore, expect a made-to-order lead time and use external guides to prevent rod bending over this long distance. If downsizing is possible, a 40mm bore provides 628N push at 0.5MPa. The -S magnet means you must switch to CMSG/DMSG/EMSG sensors for the SAU. The air cushion only decelerates the piston; for load holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU32X1200S
- ✓ 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 SU32X1200S FAQ
Yes, the SU32X1200S is discontinued. The direct replacement is the SAU32X1200S, which shares the same 32mm bore, 1200mm stroke, 1/8" port, output force, and SC-series mounting accessories.
The bore provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. The -S magnet on this SU worked with legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
