This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X225S, 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 SU32X225S
The AirTAC SU32~50 Standard Cylinder SU32X225S is a double-acting profile-type standard cylinder with a Ø32mm bore and 225mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X225S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X225S
The AirTAC SU32X225S is a discontinued double-acting profile-type cylinder with a 32mm bore and 225mm stroke. Delivering 402N push force at 0.5MPa via a 1/8" port, its direct replacement is the SAU32X225S, preserving the original body, force, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace this unit's legacy CS1-B/DS1-B switches, and adds an optional SAUF built-in valve. The cushion only decelerates; use a rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X225S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X225S 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 SU32X225S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×225 | 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 SU32X225S Is Used
Small Part Ejection
Uses the 402N push at 0.5MPa to eject light machined components from a fixture, fitting neatly into compact machinery.
Replacing the Airtac SU32~50 Standard Cylinder SU32X225S with the SAU32X225S
To replace this SU32X225S, order the SAU32X225S, confirming the 32mm bore, 225mm stroke, 1/8" port, and M10x1.25 rod thread. Because this SKU has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. For higher force, the 40mm bore yields 628N push at 0.5MPa. At 225mm, guide side loads to prevent rod bending. The cushion only decelerates; add a pilot-operated check valve to hold loads. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU32X225S
- ✓ 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 SU32X225S FAQ
Yes, the SU32X225S is discontinued. The direct replacement is the SAU32X225S, which maintains the same 32mm bore, 225mm stroke, 402N force, 1/8" port, and SC-series mounting.
It delivers 402N push and 345N pull at 0.5MPa, 563N at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. The -S magnet works with legacy CS1-B/DS1-B switches; the SAU replacement uses CMSG/DMSG/EMSG sensors.
