This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X220S, 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 SU32X220S
The AirTAC SU32~50 Standard Cylinder SU32X220S is a double-acting profile-type standard cylinder with a Ø32mm bore and 220mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X220S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X220S
The AirTAC SU32X220S is a discontinued double-acting profile-type cylinder with a 32mm bore and 220mm stroke. Delivering 402N push force at 0.5MPa via a 1/8" port, its extruded aluminum body is more compact than an ISO 15552 unit. AirTAC replaced it with the SAU32X220S direct replacement: identical bore, stroke, output, and SC-series mounting.
Because this SKU includes a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU successor transitions to CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF valve-integrated variant this series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X220S 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 SAU32X220S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×220 | 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.
Where the Airtac SU32~50 Standard Cylinder SU32X220S Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture with a safe 241N working load over a 220mm travel distance.
Package Diverting
Actuates a diverting arm on a packaging line, utilizing the 20kg vertical lift capacity to reroute small cartons efficiently.
Bin Sorting
Selects and pushes items into sorting bins, where the compact 32mm profile body saves valuable space in tight automation cells.
Replacing the Airtac SU32~50 Standard Cylinder SU32X220S with the SAU32X220S
To replace this SU32X220S, order the SAU32X220S. Confirm your 1/8" port thread (PT/G/NPT), M10x1.25 rod end, and SC-series mounting (LB/FA/FB/CA/CB). The -S magnet means you must upgrade sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG. For higher force, the 40mm bore yields 628N push at 0.5MPa; for less, options are limited below 32mm. At 220mm stroke, guide rods prevent side-load bending. A plain cylinder drifts without air; use an external rod lock for load holding. Consider the SAUF variant if you need a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU32X220S
- ✓ 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 SU32X220S FAQ
Yes, the SU32X220S is discontinued. The direct replacement is the SAU32X220S, matching the 32mm bore, 220mm stroke, 402N force, 1/8" port, and SC-series mounting. You simply order the SAU equivalent.
It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and 82kgf max at 1.0MPa. Because this is an -S magnet model, it used CS1-B/DS1-B switches; the SAU32X220S replacement requires current CMSG/DMSG/EMSG sensors instead.
