This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X220S, 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 SU40X220S
The AirTAC SU32~50 Standard Cylinder SU40X220S is a double-acting profile-type standard cylinder with a Ø40mm bore and 220mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X220S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU40X220S
The AirTAC SU40X220S is a discontinued double-acting profile-type cylinder with a 40mm bore and 220mm stroke. It delivers 628N push force at 0.5MPa via a 1/4" port. AirTAC replaced this EOL unit with the SAU40X220S, a direct replacement retaining the exact bore, stroke, force, port and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used on this -S magnet model, and adds a SAUF built-in-valve option. The extruded aluminum body is more compact than an ISO 15552 equivalent.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X220S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X220S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU40X220S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 40 | 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 SU40X220S Is Used
Package Diversion
Pushes lightweight cartons off a sorting line using a safe 377N working load, fitting neatly within existing SC-series bracket clearances.
Clamp Actuation
Secures medium workpieces during machining, where the compact profile body saves space compared to older ISO 15552 units.
Replacing the Airtac SU32~50 Standard Cylinder SU40X220S with the SAU40X220S
To replace the SU40X220S, order the SAU40X220S, confirming the 40mm bore, 220mm stroke, M12x1.25 rod thread, 1/4" port, and SC-series mounting. Because this SKU has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If stepping up to a 50mm bore yields 982N push at 0.5MPa, while dropping to 32mm provides 402N. A plain cylinder drifts without live air; the cushions only decelerate, so use an external rod lock for held loads. At 220mm stroke, rod bending is low, but ensure adequate guiding. The SAUF variant offers an integrated 4M valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU40X220S
- ✓ 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 SU40X220S FAQ
Yes, the SU40X220S is discontinued. The direct replacement is the AirTAC SAU40X220S. It shares the identical 40mm bore, 220mm stroke, 628N force at 0.5MPa, 1/4" port, and SC-series mounting, so it fits the same application directly.
The 40mm bore provides 628N push and 528N pull at 0.5MPa, 879N push at 0.7MPa, and a theoretical max of 128kgf at 1.0MPa. Because this is an -S magnet model, the original CS1-B/DS1-B switches are obsolete; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
