This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X150S, 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 SU40X150S
The AirTAC SU32~50 Standard Cylinder SU40X150S is a double-acting profile-type standard cylinder with a Ø40mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X150S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X150S
The AirTAC SU40X150S is a discontinued double-acting profile-type cylinder with a 40mm bore and 150mm stroke. It delivers 628N push and 528N pull at 0.5MPa via a 1/4" port. AirTAC replaced this unit with the SAU40X150S, a direct upgrade retaining the exact bore, stroke, output force, and SC-series mounting footprint.
When upgrading, note the SAU uses current CMSG/DMSG/EMSG sensors instead of this model's legacy CS1-B/DS1-B switches. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X150S 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 SAU40X150S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Small Part Ejection
Ejects molded components from a machine fixture with a 150mm travel and 628N thrust at 0.5MPa operating pressure.
Replacing the Airtac SU32~50 Standard Cylinder SU40X150S with the SAU40X150S
To replace this discontinued SU40X150S, order the SAU40X150S direct equivalent, confirming the 40mm bore, 150mm stroke, 1/4" port, M12x1.25 rod thread, and SC-series mounting. Because this SKU includes a magnet (-S), you must switch from legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family on the SAU. If your application needs higher force, the 50mm bore provides 982N push at 0.5MPa; if less force is acceptable, the 32mm bore yields 402N. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the standard cushion only decelerates. At 150mm stroke, side-load is minimal, but always guide the rod to prevent bending. The SAU line also offers a SAUF variant with a built-in 4M solenoid valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU40X150S
- ✓ 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 SU40X150S FAQ
Yes, the SU40X150S is discontinued. The direct replacement is the AirTAC SAU40X150S. It shares the same 40mm bore, 150mm stroke, 628N push force at 0.5MPa, 1/4" port, and SC-series mounting accessories. You can install the SAU directly into the same application.
The cylinder provides 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. Because your SU40X150S has a magnet (-S), note that the SAU replacement upgrades the sensor groove compatibility from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family.
