This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X575S, 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 SU40X575S
The AirTAC SU32~50 Standard Cylinder SU40X575S is a double-acting profile-type standard cylinder with a Ø40mm bore and 575mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X575S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X575S
The AirTAC SU40X575S is a discontinued double-acting profile cylinder with a 40mm bore and 575mm stroke. Delivering 628N push force at 0.5MPa, it features a 1/4" port and adjustable cushions. AirTAC replaced this EOL unit with the SAU40X575S, a direct replacement retaining the exact body, stroke, force, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace this unit's legacy CS1-B/DS1-B switches, and adds an optional SAUF built-in valve variant. The 575mm stroke requires external guides to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X575S 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 SAU40X575S 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 SU40X575S Is Used
Compact Assembly Ejector
Ejects machined parts from a tight cell using the 628N thrust, fitting into spaces where a standard ISO cylinder would be too long for the 40mm bore.
Replacing the Airtac SU32~50 Standard Cylinder SU40X575S with the SAU40X575S
To replace this SU40X575S, order the SAU40X575S, confirming the 40mm bore, 575mm stroke, 1/4" port, M12x1.25 rod thread, and SC-series mounting. If downsizing, a 32mm bore yields 402N push at 0.5MPa; if upsizing, a 50mm bore provides 982N. Because the 575mm stroke is long, use external guides to prevent rod bending under side loads. Note that the -S magnet on this legacy model used CS1-B/DS1-B switches, but the SAU replacement requires current CMSG/DMSG/EMSG sensors. A plain cylinder does not hold load without live air; the cushions only decelerate, so add a pilot-operated check valve or rod lock for vertical holding. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU40X575S
- ✓ 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 SU40X575S FAQ
Yes, the SU40X575S is discontinued. The direct replacement is the AirTAC SAU40X575S. It matches the 40mm bore, 575mm stroke, 628N force at 0.5MPa, 1/4" port, and SC-series mounting. The main change is that the -S magnet on the SAU works with current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 40mm bore features a 1/4" port. At 0.5MPa it provides 628N push and 528N pull force. At 0.7MPa the push force is 879N, and at 0.9MPa it is 1130N. The theoretical maximum force is 128kgf at 1.0MPa.
