This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X95S, 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 SU40X95S
The AirTAC Airtac SU32~50 Standard Cylinder SU40X95S is a double-acting profile-type standard cylinder with a Ø40mm bore and 95mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X95S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X95S
The AirTAC SU40X95S is a discontinued double-acting profile-type cylinder with a 40mm bore and 95mm stroke. It delivers 628N push and 528N pull at 0.5MPa, operating via a 1/4" port. AirTAC replaced this EOL unit with the SAU40X95S, a direct alternative retaining the exact bore, stroke, output force, port size and SC-series mounting footprint.
Because this SKU includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches; upgrading to the SAU requires switching to current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X95S 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 SAU40X95S 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 SU40X95S Is Used
Package Diverting
Pushes light-to-medium cartons on a packing line using the 628N push force at 0.5MPa, with the 95mm stroke moving goods cleanly between adjacent belts.
Component Clamping
Secures workpieces during light machining using the 528N pull force, while the compact extruded profile saves space compared to standard ISO cylinders.
Replacing the Airtac SU32~50 Standard Cylinder SU40X95S with the SAU40X95S
To replace the SU40X95S, order the SAU40X95S and verify your 1/4" port threads (PT, G or NPT) and SC-series mounting hardware. Since this is an -S model, budget for CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches. If your application needs higher force, the neighbouring 50mm bore provides 982N push at 0.5MPa; if less is required, the 32mm bore offers 402N. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for secure load holding. For self-switching needs, consider the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU40X95S
- ✓ 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 SU40X95S FAQ
Yes, the AirTAC SU40X95S is discontinued and end-of-life. The direct replacement is the SAU40X95S. It matches the 40mm bore, 95mm stroke, 628N force, 1/4" port and SC-series mounting accessories, so no mechanical redesign is needed.
At 0.5MPa it provides 628N push and 528N pull, rising to 879N push at 0.7MPa and 1130N at 0.9MPa, with a theoretical max of 128kgf at 1.0MPa. Because this is an -S magnet model, the original CS1-B/DS1-B switches are obsolete; the SAU replacement requires CMSG, DMSG or EMSG sensors.
