This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X35S, 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 SU50X35S
The AirTAC Airtac SU32~50 Standard Cylinder SU50X35S is a double-acting profile-type standard cylinder with a Ø50mm bore and 35mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X35S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X35S
The AirTAC SU50X35S is a discontinued double-acting profile-type cylinder with a 50mm bore and 35mm stroke, delivering 982N push force at 0.5MPa through a 1/4" port. AirTAC replaced this unit with the SAU50X35S, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series mounting compatibility.
Because this SU model includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches, whereas the SAU replacement now takes current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X35S 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 SAU50X35S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 50 | Bore size in mm. |
| ×35 | 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 SU50X35S Is Used
Component Clamping
Ideal for securing medium-weight machined parts during milling or drilling, utilizing the 982N push force at 0.5MPa for rigid, stable holding without deflection.
Package Diverting
Provides a fast 35mm stroke to push small to medium cartons off a main conveyor line, operating efficiently within the 30-800mm/s speed range.
Pallet Stopper Gate
Functions as a compact pneumatic stop in low-profile pallet handling systems, where the extruded aluminum body saves space compared to standard ISO cylinders.
Replacing the Airtac SU32~50 Standard Cylinder SU50X35S with the SAU50X35S
To replace this discontinued SU50X35S, order the SAU50X35S and verify your 1/4" port threads (PT, G, or NPT) along with your SC-series mounting hardware (LB, FA, FB, CA, CB, or TC). If your machine relied on the -S magnet for positioning, note that your legacy CS1-B/DS1-B switches must be swapped to the SAU's CMSG/DMSG/EMSG sensor family. For force verification, the 50mm bore yields 982N push at 0.5MPa; if you need less force, step down to a 40mm bore (628N), or step up to a 63mm bore (1559N) for heavier loads. Remember that a standard cylinder drifts without live air—the cushion only decelerates near stroke end—so install an external rod lock or pilot-operated check valve if the load must be held. The SAUF valve-integrated option is also worth considering if you need self-switching logic.
Replacement checklist
- ✓ Same bore / stroke → SAU50X35S
- ✓ 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 SU50X35S FAQ
Yes, the AirTAC SU50X35S is discontinued and end-of-life. The direct replacement is the SAU50X35S. It shares the identical 50mm bore, 35mm stroke, 1/4" port, output force, and SC-series mounting accessories, so it fits the same application directly.
The 50mm bore generates 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical maximum of 200kgf at 1.0MPa. Because this SKU has a magnet (-S), it used legacy CS1-B/DS1-B switches; when upgrading to the SAU replacement, you must switch to the current CMSG/DMSG/EMSG sensor family.
