This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X20S, 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 SU32X20S
The AirTAC Airtac SU32~50 Standard Cylinder SU32X20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 20mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X20S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X20S
The AirTAC SU32X20S is a discontinued double-acting profile cylinder with a 32mm bore and 20mm stroke, delivering 402N push force at 0.5MPa. AirTAC replaced this legacy unit with the SAU32X20S, a direct alternative retaining the exact 1/8" port, M10x1.25 rod thread, and SC-series mounting compatibility.
Because this SU model includes a magnet (-S), it originally used CS1-B/DS1-B switches; the SAU replacement upgrades to current CMSG/DMSG/EMSG sensors. The extruded aluminum body is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X20S 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 SAU32X20S 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 SU32X20S Is Used
Short Stroke Ejection
The 20mm stroke provides rapid, compact ejection of lightweight parts from automated assembly tooling.
Replacing the Airtac SU32~50 Standard Cylinder SU32X20S with the SAU32X20S
To replace this discontinued SU32X20S, order the SAU32X20S, confirming the 32mm bore, 20mm stroke, 1/8" port, and SC-series mounting. The -S magnet means you must switch legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. If you need higher force, the neighboring 40mm bore provides 628N push at 0.5MPa. For load holding, note that a plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for suspended loads. The SAU family also adds a SAUF built-in-valve option the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU32X20S
- ✓ 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 SU32X20S FAQ
Yes, the AirTAC SU32X20S is discontinued. The direct replacement is the SAU32X20S, which matches the 32mm bore, 20mm stroke, 402N force, 1/8" port, and SC-series mounting. You simply order the SAU equivalent.
The SAU32X20S provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and an 82kgf max at 1.0MPa. Because your SU32X20S has a magnet (-S), you must upgrade from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors on the SAU model.
