This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X360S, 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.

The AirTAC Airtac SU32~50 Standard Cylinder SU40X360S is a double-acting profile-type standard cylinder with a Ø40mm bore and 360mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X360S, which matches its bore, stroke, force and mounting.
The AirTAC SU40X360S is a discontinued double-acting profile cylinder with a 40mm bore and 360mm stroke. Delivering 628 N push force at 0.5 MPa, it features an extruded aluminum body and a 1/4" port. AirTAC replaced this legacy unit with the SAU40X360S, a direct replacement retaining the exact bore, stroke, output force, port size and SC-series mounting.
The -S magnet on this SU worked with legacy CS1-B/DS1-B switches, but the SAU replacement uses current CMSG/DMSG/EMSG sensors. The SAU family also adds a SAUF built-in-valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X360S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X360S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×360 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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.
Pushes cartons off a sorting line using 628 N of thrust, with the 360mm stroke clearing wider conveyor belts.
Acts as a pneumatic stop gate for pallets, retracting to release flow while fitting compact SC-series mounts.
Ejects machined parts from a fixture, using the magnetic -S piston for position confirmation.
To replace the SU40X360S, order the SAU40X360S. Confirm the 40mm bore, 360mm stroke, 1/4" port, M12x1.25 rod thread and SC-series mounting (LB/FA/FB/CA/CB) match your jig. Because this has an -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. Sizing both ways: a 32mm bore gives 402 N push at 0.5 MPa (too small), while a 50mm bore gives 982 N. A plain cylinder does not hold load on air loss; the 21mm cushion only decelerates, so use an external rod lock or pilot-operated check valve for holding. The 360mm stroke requires an external guide to prevent rod bending under side loads. If you need self-switching, explore the SAUF valve-integrated variant.
Replacement checklist
Yes, the AirTAC SU40X360S is discontinued. The direct replacement is the SAU40X360S. It shares the same 40mm bore, 360mm stroke, 628 N force, 1/4" port and SC-series mounting, so it fits the same application.
At 0.5 MPa it pushes 628 N and pulls 528 N; at 0.7 MPa it pushes 879 N, with a theoretical max of 128 kgf at 1.0 MPa. The -S suffix means it has a magnet for legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU40X360S replacement — usually within 7-8 hours.
