This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X580, 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 SU40X580
The AirTAC SU32~50 Standard Cylinder SU40X580 is a double-acting profile-type standard cylinder with a Ø40mm bore and 580mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X580, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X580
The AirTAC SU40X580 is a discontinued double-acting profile-type cylinder with a 40mm bore and 580mm stroke. Delivering 628N push force at 0.5MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same bore. AirTAC replaced this EOL unit with the SAU40X580, a direct matching the 1/4" port, M12x1.25 rod thread, and SC-series mounts.
The SAU upgrade keeps the bore, stroke, and force identical. This base SU40X580 lacks a magnet, so it cannot accept position sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X580 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 SAU40X580 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 SU40X580 Is Used
Long-Stroke Diversion
Pushes packages across transfer lines over the 580mm travel, utilizing the 628N push force to overcome guide friction without side-loading the rod.
Compact Assembly Ejector
Ejects machined parts from fixtures where the shorter profile body saves machine envelope compared to standard ISO 15552 cylinders of the same 40mm bore.
Replacing the Airtac SU32~50 Standard Cylinder SU40X580 with the SAU40X580
To replace the SU40X580, order the SAU40X580 direct equivalent, verifying your 1/4" port, M12x1.25 rod thread, and SC-series mounting hardware. If you need position sensing, note this exact SKU has no magnet and cannot take a switch; a legacy -S SU used CS1-B/DS1-B switches, while the new SAU requires CMSG/DMSG/EMSG sensors. At 580mm stroke, prevent rod bending by guiding the load externally to avoid side-load damage. If dropping a load on air loss is unsafe, add an external rod lock or pilot-operated check valve, as cushions only decelerate. For higher force, the 50mm bore offers 982N push at 0.5MPa; for less space, the 32mm bore provides 402N.
Replacement checklist
- ✓ Same bore / stroke → SAU40X580
- ✓ 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 SU40X580 FAQ
Yes, the AirTAC SU40X580 is discontinued and end-of-life. The direct replacement is the SAU40X580. It shares the same 40mm bore, 580mm stroke, 628N output force, 1/4" port, and SC-series mounting accessories, so it fits the same application directly.
At 0.5MPa it provides 628N push and 528N pull; 879N push at 0.7MPa; 1130N at 0.9MPa; and a theoretical max of 128kgf at 1.0MPa. This specific SU40X580 SKU lacks a magnet and cannot accept sensors, whereas the SAU replacement uses CMSG/DMSG/EMSG switches.
