This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X225S, 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 SU50X225S
The AirTAC SU32~50 Standard Cylinder SU50X225S is a double-acting profile-type standard cylinder with a Ø50mm bore and 225mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X225S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X225S
The AirTAC SU50X225S is a discontinued double-acting profile cylinder with a 50mm bore and 225mm stroke. Delivering 982N push force at 0.5MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same size. AirTAC replaced this with the SAU50X225S, a direct sharing the exact 1/4" port, M16x1.5 rod, and SC-series mounts.
The -S magnet on this unit worked with legacy CS1-B/DS1-B switches, but the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF valve-integrated option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X225S 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 SAU50X225S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU50X225S Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using 982N thrust, with the 225mm stroke clearing guide rails easily.
Pallet Stops
Acts as a pneumatic stop for inbound pallets, decelerating the load via its 21mm adjustable air cushions at both ends.
Clamp Actuation
Secures workpieces during machining, providing a safe 589N clamping force while fitting into compact cell footprints.
Replacing the Airtac SU32~50 Standard Cylinder SU50X225S with the SAU50X225S
To replace this SU50X225S, order the SAU50X225S direct: confirm the 50mm bore, 225mm stroke, 1/4" port, and SC-series mounting hardware. Because this SKU has the -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. If you need higher force, the 63mm bore offers 1559N push at 0.5MPa; if lower force is acceptable, the 40mm bore provides 628N. For automated cycling, consider the SAUF variant with its built-in 4M solenoid valve. Remember, a standard cylinder drifts without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU50X225S
- ✓ 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 SU50X225S FAQ
Yes, the SU50X225S is discontinued. The direct replacement is the AirTAC SAU50X225S. It matches the 50mm bore, 225mm stroke, 982N force, 1/4" port, and SC-series mounting, so no mechanical changes are needed.
The SAU50X225S provides 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a 200kgf max at 1.0MPa. Because your SU has the -S magnet, note that the SAU replaces the old CS1-B/DS1-B switches with the current CMSG/DMSG/EMSG sensor family.
