This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X570, 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 SU40X570
The AirTAC Airtac SU32~50 Standard Cylinder SU40X570 is a double-acting profile-type standard cylinder with a Ø40mm bore and 570mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X570, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X570
The AirTAC SU40X570 is a discontinued double-acting profile-type cylinder with a 40mm bore and 570mm stroke, delivering 628N push force at 0.5MPa. AirTAC replaced it with the SAU40X570 direct replacement, matching the exact bore, stroke, output force, 1/4" port, and SC-series mounting accessories.
Because this is a non-magnet SKU, it cannot accept a sensor. The SAU upgrade uses current CMSG/DMSG/EMSG switches and adds a SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X570 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 SAU40X570 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 SU40X570 Is Used
Carton Diverting
Pushes light packages across a transfer section using the 628N push force at 0.5MPa, with the 570mm stroke covering the full conveyor belt width.
Pallet Push-Off
Acts as a sweep arm to clear loose components from a pallet, requiring an external guide to support the 16mm rod across the 570mm extension.
Replacing the Airtac SU32~50 Standard Cylinder SU40X570 with the SAU40X570
To replace this discontinued SU40X570, order the SAU40X570 direct equivalent, verifying your 1/4" port, M12x1.25 rod thread, and SC-series mounts. Since this 570mm stroke lacks a magnet (-S), it cannot take a sensor; if you need position detection on the SAU, you must order an -S model and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. At 570mm, the 16mm rod is vulnerable to side-loading and bending, so use an external guide to prevent premature seal wear. A plain cylinder drifts on air loss—the 21mm cushions only decelerate near stroke end, so add a pilot-operated check valve or rod lock for load holding. If you need more force, the 50mm bore offers 982N push at 0.5MPa; if less is acceptable, the 32mm bore provides 402N.
Replacement checklist
- ✓ Same bore / stroke → SAU40X570
- ✓ 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 SU40X570 FAQ
Yes, the SU40X570 is discontinued. The direct replacement is the AirTAC SAU40X570, which matches the 40mm bore, 570mm stroke, 628N force at 0.5MPa, 1/4" port, and SC-series mounting.
It delivers 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. The 21mm cushions only decelerate the piston near stroke end; a plain cylinder cannot hold a load on air loss, so use an external rod lock or pilot-operated check valve.
