This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X235, 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 SU50X235
The AirTAC SU32~50 Standard Cylinder SU50X235 is a double-acting profile-type standard cylinder with a Ø50mm bore and 235mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X235, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X235
The AirTAC SU50X235 is a discontinued double-acting profile-type cylinder with a 50mm bore and 235mm stroke. Delivering 982N push force at 0.5MPa, it features an extruded aluminum barrel making it more compact than a same-bore ISO 15552 unit. The direct replacement is the SAU50X235, matching the 50mm bore, 235mm stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting.
Since this SKU lacks the -S magnet, it cannot accept a sensor. If sensing is needed, the SAU replacement requires current CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B. Note that cushions only decelerate; use a rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X235 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 SAU50X235 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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 SU50X235 Is Used
Package Diverting
Pushes cartons at 30-800 mm/s on packaging lines, using the 982N thrust to redirect moderate loads without overshoot.
Pallet Stopper
Acts as a pneumatic stop for low-inertia pallets, where the 21mm adjustable cushion decelerates the 50kg safe load smoothly.
Clamp Actuation
Secures workpieces during machining, providing 589N of safe holding force while fitting into compact profile-body spaces.
Replacing the Airtac SU32~50 Standard Cylinder SU50X235 with the SAU50X235
To replace the SU50X235, order the SAU50X235, confirming the 1/4" port, M16x1.5 thread, and SC-series mounts (LB/FA/FB/CA/CB). This non-magnetic SKU cannot take a switch; if sensing is needed, the SAU uses CMSG/DMSG/EMSG sensors. For sizing both ways: a 40mm bore gives 628N push at 0.5MPa, while a 63mm bore yields 1559N. At 235mm stroke, guide the load to prevent rod bending. The cylinder drifts on air loss; use an external rod lock for holding. The SAUF variant adds a built-in valve the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU50X235
- ✓ 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 SU50X235 FAQ
Yes, the SU50X235 is discontinued. The direct replacement is the AirTAC SAU50X235. It matches the 50mm bore, 235mm stroke, 982N force, 1/4" port, and SC-series mounting accessories perfectly.
At 0.5MPa it pushes 982N and pulls 825N; at 0.7MPa it pushes 1374N, with a theoretical max of 200kgf at 1.0MPa. This specific non-S SKU cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
