This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X105, 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 SU32X105
The AirTAC Airtac SU32~50 Standard Cylinder SU32X105 is a double-acting profile-type standard cylinder with a Ø32mm bore and 105mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X105, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X105
The AirTAC SU32X105 is a discontinued double-acting profile-type cylinder with a 32mm bore and 105mm stroke, delivering 402N push force at 0.5MPa. Its extruded aluminum barrel makes it more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this unit with the SAU32X105, a direct equivalent sharing the exact bore, stroke, output force, 1/8" port, and SC-series mounting.
This non-magnet SKU cannot accept a sensor. If sensing is needed, the SAU replacement uses modern CMSG/DMSG/EMSG switches, whereas the legacy SU used CS1-B/DS1-B. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X105 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 SAU32X105 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 SU32X105 Is Used
Small Part Ejection
Provides reliable 402N push force at 0.5MPa to eject small machined components from a fixture on an automated lathe.
Bin Push-Off
Cycles a 105mm stroke to push small totes or bins from a gravity conveyor onto an outbound packing station.
Replacing the Airtac SU32~50 Standard Cylinder SU32X105 with the SAU32X105
To replace the SU32X105, order the SAU32X105. Confirm your 1/8" port thread (PT/G/NPT), M10x1.25 rod-end, and SC-series mounting (LB/FA/FB/CA/CB). Because this is a non-magnet SKU, it cannot accept a sensor; if you need position detection, specify an SAU-S model and upgrade to CMSG/DMSG/EMSG switches. The 32mm bore yields 402N push and 345N pull at 0.5MPa; if undersized, the 40mm bore offers 628N push. A plain cylinder drifts on air loss—the 21mm cushions only decelerate the piston, so use an external rod lock for held loads. The SAUF built-in-valve option is available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU32X105
- ✓ 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 SU32X105 FAQ
Yes, the SU32X105 is discontinued. The direct replacement is the AirTAC SAU32X105. It shares the same 32mm bore, 105mm stroke, output force, 1/8" port, and SC-series mounting accessories, so it fits the same application without modification.
The 32mm bore features a 1/8" port and M10x1.25 rod thread. It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa. Note that this non-magnet SKU cannot accept a sensor.
