This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X750, 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 SU40X750
The AirTAC SU32~50 Standard Cylinder SU40X750 is a double-acting profile-type standard cylinder with a Ø40mm bore and 750mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X750, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X750
The AirTAC SU40X750 is a discontinued double-acting profile-type cylinder with a 40mm bore and 750mm stroke. Delivering 628N push force at 0.5MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same size. AirTAC replaced it with the SAU40X750, a direct upgrade retaining the exact 1/4" port, M12x1.25 rod thread, and SC-series mounting.
This SKU lacks a magnet (-S) and cannot accept a sensor; if sensing is needed, the SAU replacement uses modern CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X750 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 SAU40X750 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 SU40X750 Is Used
Long-Stroke Diversion
Actuates routing gates on packaging lines over a 750mm span, utilizing the 628N thrust to push heavy cartons smoothly.
Vertical Material Lift
Raises lightweight totes up to 32kg in pick modules, taking advantage of the compact 40mm profile body to save space.
Component Ejection
Pushes machined parts out of a CNC workspace, where the adjustable 21mm cushions absorb kinetic energy at stroke end.
Replacing the Airtac SU32~50 Standard Cylinder SU40X750 with the SAU40X750
To replace this SU40X750 with the SAU40X750, confirm the 40mm bore, 750mm stroke, 1/4" port, and SC-series mounting accessories are compatible with your existing setup. Since this is a non-magnet SKU, it cannot take a sensor; if you require position detection, order the SAU40X750S and note the switch family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. You can also explore the SAUF model if you need a built-in valve. At 750mm, the 16mm rod is susceptible to bending under side loads, so use external guides to prevent damage. For neighboring sizes, a 32mm bore yields 402N push at 0.5MPa, while a 50mm bore provides 982N. Note that air cushions only decelerate the load; they do not hold it on air loss, so add an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU40X750
- ✓ 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 SU40X750 FAQ
Yes, the SU40X750 is discontinued. The direct replacement is the AirTAC SAU40X750. It shares the identical 40mm bore, 750mm stroke, 1/4" port, output force, and SC-series mounting, so it fits the same application directly.
The 40mm bore generates 628N push and 528N pull at 0.5MPa, 879N at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. This specific SKU has no magnet and cannot take a sensor. If you need sensing, the SAU replacement requires CMSG/DMSG/EMSG switches, replacing the older CS1-B/DS1-B.
