This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X455, 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 SU40X455
The AirTAC SU32~50 Standard Cylinder SU40X455 is a double-acting profile-type standard cylinder with a Ø40mm bore and 455mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X455, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X455
The AirTAC SU40X455 is a discontinued double-acting profile-type cylinder with a 40mm bore and 455mm stroke. It delivers 628N push and 528N pull at 0.5MPa, utilizing a 1/4" port and M12x1.25 rod thread. AirTAC replaced this EOL unit with the SAU40X455, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
Because this SKU lacks a magnet, it cannot accept a sensor; furthermore, the SAU family upgrades sensing to CMSG/DMSG/EMSG switches and introduces the SAUF built-in-valve variant. Note that the 455mm stroke requires external guides to prevent rod bending, and a plain cylinder needs an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X455 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 SAU40X455 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 SU40X455 Is Used
Package Diverting
Actuates diverting arms on packaging lines, using the 628N push force at 0.5MPa to push cartons reliably without requiring full system pressure.
Light Pressing
Performs low-force pressing and seating of small pins or components, relying on the 21mm adjustable end cushions to decelerate the 455mm travel.
Replacing the Airtac SU32~50 Standard Cylinder SU40X455 with the SAU40X455
To replace the SU40X455, order the SAU40X455 direct equivalent, confirming the 40mm bore, 455mm stroke, 1/4" port, and PT thread. Reuse your existing SC-series mounting brackets. Since this is a no-magnet SKU, it cannot support sensing; if you need position detection on the SAU, specify the -S option and migrate to CMSG/DMSG/EMSG switches. For the 455mm stroke, add external guides to prevent rod bending under side loads. If you need higher force, step up to a 50mm bore (982N push at 0.5MPa); if smaller works, a 32mm bore yields 402N. A plain cylinder drifts on air loss, so use a pilot-operated check valve or rod lock for held loads. The SAUF variant integrates a 4M valve if you want to simplify plumbing.
Replacement checklist
- ✓ Same bore / stroke → SAU40X455
- ✓ 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 SU40X455 FAQ
Yes, the SU40X455 is discontinued. The direct replacement is the AirTAC SAU40X455. It shares the same 40mm bore, 455mm stroke, 1/4" port, force, and SC-series mounting, so it drops directly into the same application.
It delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. This specific SKU has no magnet and cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches if sensing is required.
