This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X235S, 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 SU50X235S
The AirTAC SU32~50 Standard Cylinder SU50X235S 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 SAU50X235S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X235S
The AirTAC SU50X235S is a discontinued double-acting profile-type cylinder with a 50mm bore and 235mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port. AirTAC replaced this unit with the SAU50X235S, a direct alternative retaining the exact bore, stroke, output force, port size and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used on this -S model. Note that 235mm is a nonstandard stroke. The SAUF variant also adds a built-in 4M solenoid valve the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X235S 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 SAU50X235S 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 SU50X235S Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using the 982N push force at 0.5MPa, with the 235mm stroke clearing adjacent lanes.
Pallet Stops
Acts as a pneumatic stop for pallets entering a wrapping station, handling the 50kg vertical-equivalent load safely.
Clamp Actuation
Drives mid-force clamping fixtures on machining cells, reusing existing SC-series mounts with the direct SAU replacement.
Replacing the Airtac SU32~50 Standard Cylinder SU50X235S with the SAU50X235S
To replace the SU50X235S, order the SAU50X235S, verifying the 1/4" port, M16x1.5 rod thread and SC-series mounting. Because the -S magnet is present, prepare to swap legacy CS1-B/DS1-B switches for current CMSG/DMSG/EMSG sensors. For load sizing, this 50mm bore yields 982N push at 0.5MPa; a neighbouring 63mm bore provides 1559N if more force is needed. A plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for held loads. The SAUF valve-integrated option can simplify actuation. As the 235mm stroke is nonstandard and exceeds 200mm, ensure adequate guiding to prevent rod bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU50X235S
- ✓ 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 SU50X235S FAQ
Yes, the AirTAC SU50X235S is discontinued. The direct replacement is the SAU50X235S. It matches the 50mm bore, 235mm stroke, 982N force, 1/4" port and SC-series mounting, so it fits the same application.
At 0.5MPa it pushes 982N and pulls 825N; at 0.7MPa it pushes 1374N, with a theoretical max of 200kgf at 1.0MPa. Because this is an -S model, the legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the SAU.
