This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X720S, 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 SU32X720S is a double-acting profile-type standard cylinder with a Ø32mm bore and 720mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X720S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X720S is a discontinued double-acting profile-type cylinder with a 32mm bore and 720mm stroke. Delivering 402N push force at 0.5MPa, it features an extruded aluminum barrel and adjustable cushions. AirTAC replaced it with the SAU32X720S direct replacement: identical body, bore, output, 1/8" port, and SC-series mounts.
Because this SKU includes a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU successor upgrades to CMSG/DMSG/EMSG sensors and adds a SAUF built-in-valve option. At 720mm, prevent rod bending by using external guides.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X720S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X720S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×720 | 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.
Cycles lightweight storage bins laterally across gravity rollers, taking advantage of the compact 32mm profile body.
Ejects machined components from a fixture with a long 720mm extraction path, requiring external guide rods to prevent side-load wear.
To replace this discontinued SU32X720S, order the SAU32X720S. Confirm the 32mm bore, 720mm stroke, 1/8" port, and M10x1.25 rod thread. The -S magnet means you must switch legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. For load holding, note that neither cylinder locks without live air; use a pilot-operated check valve. If you need more force, the 40mm bore offers 628N push at 0.5MPa; if less, check smaller bores. The SAUF variant integrates a 4M valve if needed. Finally, at 720mm stroke, support the load with external guides to prevent rod bending.
Replacement checklist
Yes, the SU32X720S is discontinued. The direct replacement is the SAU32X720S, matching the 32mm bore, 720mm stroke, 1/8" port, force, and SC-series mounting. You simply order the SAU equivalent.
It delivers 402N push and 345N pull at 0.5MPa, 563N at 0.7MPa, and an 82kgf max at 1.0MPa. Because this is the -S magnet version, it used 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 SAU32X720S replacement — usually within 7-8 hours.
