This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X105S, 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 SU50X105S
The AirTAC SU32~50 Standard Cylinder SU50X105S is a double-acting profile-type standard cylinder with a Ø50mm bore and 105mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X105S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X105S
The AirTAC SU50X105S is a discontinued double-acting profile-type cylinder with a 50mm bore and 105mm stroke. It delivers 982 N push force at 0.5 MPa through a 1/4" port. AirTAC replaced this unit with the SAU50X105S, a direct upgrade retaining the exact bore, stroke, force, and SC-series mounting footprint.
The SAU replacement upgrades the -S magnet sensor family from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG reed switches. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X105S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X105S 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 SU50X105S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×105 | 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 SU50X105S Is Used
Package Diverting
Pushes light-to-medium cartons off a sorting line using 982 N of thrust, fitting neatly into tight conveyor frames due to the compact profile body.
Pallet Stops
Acts as a pneumatic stop for inbound pallets, where the 105mm stroke extends a blocking pin to halt movement safely.
Component Clamping
Secures mild steel workpieces during machining, applying a safe 589 N clamping load without deflecting the 20mm piston rod.
Replacing the Airtac SU32~50 Standard Cylinder SU50X105S with the SAU50X105S
To replace this SU50X105S, order the SAU50X105S. Confirm the 1/4" port, M16x1.5 rod thread, and SC-series mounting accessories (LB/FA/FB/CA/CB) are retained. Because this SKU has the -S magnet, you must upgrade your sensors: the legacy CS1-B/DS1-B switches will not fit the SAU groove, so switch to CMSG/DMSG/EMSG. If your application needs a self-switching function, the SAU line offers a SAUF variant with a built-in 4M solenoid valve that the SU lacked. For sizing both ways, a 40mm bore provides 628 N at 0.5 MPa, while a 63mm bore yields 1559 N. Remember, a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU50X105S
- ✓ 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 SU50X105S FAQ
Yes, the SU50X105S is end-of-life. The direct replacement is the AirTAC SAU50X105S. It matches the 50mm bore, 105mm stroke, 1/4" port, output force, and SC-series mounting accessories, so it bolts directly into the same application.
At 0.5 MPa it provides 982 N push and 825 N pull, 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. Because the -S magnet is present, note that the SAU uses current CMSG/DMSG/EMSG switches instead of the old CS1-B/DS1-B sensors.
