This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X280, 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 SU32X280 is a double-acting profile-type standard cylinder with a Ø32mm bore and 280mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X280, which matches its bore, stroke, force and mounting.
The AirTAC SU32X280 is a discontinued double-acting profile-type cylinder with a 32mm bore and 280mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. AirTAC replaced this with the SAU32X280, a direct sharing the exact body, force, and SC-series mounting.
This non-magnet SKU cannot take a sensor, unlike the -S variant which used legacy CS1-B/DS1-B switches (the SAU uses CMSG/DMSG/EMSG). The SAU line also adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X280 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 SAU32X280 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×280 | 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 lightweight plastic or metal parts out of a machining center using a safe 241N working load over the 280mm travel.
Actuates a routing gate on a packaging line, where the compact 32mm profile saves space without sacrificing cycle speed.
To replace this SU32X280, order the SAU32X280. Verify your 1/8" port, M10x1.25 rod thread, and SC-series mount. This non-magnet SKU cannot accept a sensor; if you need position detection, step up to an SAU32X280S and migrate to CMSG/DMSG/EMSG switches. At 280mm stroke, guide the load to prevent rod bending. If dropping a 40mm bore is viable, it yields 628N push at 0.5MPa. Note: a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for secure load holding, as the 21mm cushions only decelerate at stroke ends.
Replacement checklist
Yes, the SU32X280 is discontinued. The direct replacement is the AirTAC SAU32X280. It matches the 32mm bore, 280mm stroke, 402N force, 1/8" port, and SC-series mounting. You can swap it directly without altering your machine layout.
It provides 402N push and 345N pull at 0.5MPa, 563N at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. This specific SKU lacks a magnet and cannot take a sensor. The magnetized SAU replacement uses modern CMSG/DMSG/EMSG switches instead of the old CS1-B/DS1-B.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X280 replacement — usually within 7-8 hours.
