This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X30S, 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 SU32X30S
The AirTAC Airtac SU32~50 Standard Cylinder SU32X30S is a double-acting profile-type standard cylinder with a Ø32mm bore and 30mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X30S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X30S
The AirTAC SU32X30S is a discontinued double-acting profile-type cylinder with a 32mm bore and 30mm stroke. Delivering 402N push force at 0.5MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same bore. The direct replacement is the SAU32X30S, matching the bore, stroke, 1/8" port, and SC-series mounting.
The -S suffix means this legacy unit uses CS1-B/DS1-B switches, whereas the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF built-in 4M valve option, which the SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X30S 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 SAU32X30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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.
Where the Airtac SU32~50 Standard Cylinder SU32X30S Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably kick lightweight plastic or aluminum parts out of a machining fixture.
Compact Sorting Diverters
Fits into tight conveyor spaces where the shorter profile body provides a space-saving advantage over standard ISO cylinders.
Pneumatic Gripper Actuation
Drives small end-effector jaws over a 30mm distance, with the 1/8" port ensuring rapid response for fast cycling.
Replacing the Airtac SU32~50 Standard Cylinder SU32X30S with the SAU32X30S
To replace this SU32X30S, order the SAU32X30S. Confirm the 1/8" port, M10x1.25 rod thread, and PT/G/NPT thread choice. Because this is a -S model, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG on the SAU. If you need more force, the neighboring 40mm bore offers 628N push at 0.5MPa; if less is acceptable, there is no smaller standard profile bore. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for held loads. The 30mm stroke is very short, so side-load rod-bending risks are minimal, but always verify guide alignment.
Replacement checklist
- ✓ Same bore / stroke → SAU32X30S
- ✓ 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 SU32X30S FAQ
Yes, the SU32X30S is discontinued. The direct replacement is the AirTAC SAU32X30S. It shares the identical 32mm bore, 30mm stroke, 1/8" port, output force, and SC-series mounting accessories, so it fits the same application directly.
At 0.5MPa it provides 402N push and 345N pull force, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAU32X30S replacement requires the current CMSG/DMSG/EMSG sensor family.
