This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X280S, 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 SU32X280S
The AirTAC Airtac SU32~50 Standard Cylinder SU32X280S 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 SAU32X280S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X280S
The AirTAC SU32X280S is a discontinued double-acting profile-type cylinder with a 32mm bore and 280mm stroke, delivering 402N push and 345N pull at 0.5MPa. AirTAC replaced this legacy unit with the SAU32X280S, a direct replacement retaining the exact extruded aluminium body, 1/8 port, M10x1.25 rod thread and SC-series mounting. Because it is a compact profile design, it is shorter than an ISO 15552 cylinder of the same bore.
This -S SKU includes a piston magnet for legacy CS1-B/DS1-B switches; the SAU successor upgrades this groove to current CMSG/DMSG/EMSG sensors. The SAU family also adds a SAUF valve-integrated option the SU line lacked. Note that a plain cylinder drifts on air loss—the cushions only decelerate.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X280S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X280S 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 SU32X280S Is Used
Small Part Ejection
Ideal for pushing light machined components out of a fixture using a safe 241N working load over a 280mm travel distance.
Package Diverting
Deploys a 280mm stroke to deflect small cartons on a conveyor belt, fitting neatly into compact machinery frames.
Bin Sorting Gates
Actuates routing flaps for lightweight inventory sorting, providing reliable 402N push force at 0.5MPa.
Replacing the Airtac SU32~50 Standard Cylinder SU32X280S with the SAU32X280S
To replace this discontinued SU32X280S, order the SAU32X280S direct equivalent, matching the 32mm bore, 280mm stroke, 1/8 port, and SC-series mounting. If stepping up force, the neighbouring 40mm bore yields 628N push at 0.5MPa; stepping down to a 25mm stroke reduces rod bending. Because this 280mm stroke exceeds 300mm when combined with side loads, ensure external guide rails to prevent rod bending. The -S magnet means you must switch from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. For load holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. If self-switching is needed, explore the SAUF built-in 4M valve variant.
Replacement checklist
- ✓ Same bore / stroke → SAU32X280S
- ✓ 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 SU32X280S FAQ
Yes, the SU32X280S is discontinued. The direct replacement is the AirTAC SAU32X280S, which shares the same 32mm bore, 280mm stroke, 402N force, 1/8 port and SC-series mounting. You just swap the cylinder and update the sensors.
The SAU32X280S provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. Because your old unit has an -S magnet, you must upgrade from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family on the SAU replacement.
