This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X1100, 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 SU40X1100
The AirTAC SU32~50 Standard Cylinder SU40X1100 is a double-acting profile-type standard cylinder with a Ø40mm bore and 1100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X1100, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X1100
The AirTAC SU40X1100 is a discontinued double-acting profile-type cylinder featuring a 40mm bore and 1100mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore and delivers 628 N of push force at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAU40X1100, a direct replacement retaining the exact bore, stroke, 1/4" port, and SC-series mounting compatibility.
Because this specific SKU lacks a magnet, it cannot accept a position sensor. If sensing is needed on the upgrade, the SAU family supports modern CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B reeds, and introduces the SAUF valve-integrated variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X1100 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X1100 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 SU40X1100 Is Used
High-Bay Extraction
Extracts totes from deep shelving racks, where the compact 40mm profile barrel saves space and the 32 kg vertical lift capacity handles loaded bins securely.
Material Transfer
Transfers workpieces between distant machine stations, relying on the adjustable 21mm air cushions at both ends to decelerate the payload smoothly.
Replacing the Airtac SU32~50 Standard Cylinder SU40X1100 with the SAU40X1100
To replace this discontinued SU40X1100, order the SAU40X1100 direct equivalent, verifying your 1/4" port thread (PT, G, or NPT), M12x1.25 rod-end thread, and SC-series mounting hardware. Since this SKU has no magnet (-S), it cannot support sensing; if your application requires switches, select an SAU model with the -S option and upgrade to CMSG/DMSG/EMSG sensors. Remember that a standard cylinder drifts without live air—the cushions only decelerate near stroke end—so use an external rod lock or pilot-operated check valve for load holding. Finally, at 1100mm of stroke, prevent rod bending by guiding the load externally to avoid side-load damage.
Replacement checklist
- ✓ Same bore / stroke → SAU40X1100
- ✓ 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 SU40X1100 FAQ
Yes, the SU40X1100 is discontinued. The direct replacement is the AirTAC SAU40X1100. It matches the original 40mm bore, 1100mm stroke, 628 N push force at 0.5 MPa, 1/4" port, and SC-series mounting, so it fits the same application without mechanical modifications.
This double-acting cylinder delivers 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and a theoretical max of 128 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor; the SAU upgrade uses CMSG/DMSG/EMSG switches if sensing is required.
