This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X1100S, 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 SU32X1100S
The AirTAC SU32~50 Standard Cylinder SU32X1100S is a double-acting profile-type standard cylinder with a Ø32mm bore and 1100mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X1100S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X1100S
The AirTAC SU32X1100S is a discontinued double-acting profile cylinder with a 32mm bore and 1100mm stroke. Because 1100mm exceeds the 1000mm standard maximum for this bore, it is a non-standard, made-to-order length. It delivers 402N push and 345N pull at 0.5MPa. AirTAC replaced this unit with the SAU32X1100S, a direct upgrade retaining the exact 1/8" port, M10x1.25 rod thread, 21mm cushions, and SC-series mounting.
The SAU replacement modernizes the sensor groove: your old CS1-B/DS1-B switches are replaced by current CMSG/DMSG/EMSG sensors, while the SAUF variant adds a built-in valve the SU lacked. Note that air cushions only decelerate; use an external rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X1100S 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 SAU32X1100S 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 SU32X1100S Is Used
Long-Stroke Material Feed
Feeds lightweight stock over 1.1 meters, relying on 21mm adjustable cushions to decelerate the 32mm piston smoothly at cycle end.
Replacing the Airtac SU32~50 Standard Cylinder SU32X1100S with the SAU32X1100S
To replace this discontinued SU32X1100S, order the SAU32X1100S, confirming the 32mm bore, 1100mm non-standard stroke, 1/8" port, and SC-series mounting. If downsizing is possible, a 40mm bore offers 628N push at 0.5MPa; if upsizing for stability, a 50mm bore yields 982N. Because the 1100mm length exceeds the 1000mm standard maximum, expect a made-to-order lead time and ensure external guides are used to prevent rod bending on this long stroke. The -S magnet transfers over, but you must upgrade from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. For load holding on air loss, add a pilot-operated check valve, and consider the SAUF variant if you need a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU32X1100S
- ✓ 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 SU32X1100S FAQ
Yes, the SU32X1100S is discontinued. The direct replacement is the SAU32X1100S, matching the 32mm bore, 1100mm stroke, 402N force, 1/8" port, and SC-series mounting.
It delivers 402N push and 345N pull at 0.5MPa, 563N at 0.7MPa, and a max of 82kgf at 1.0MPa. The -S magnet works with legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
