This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X180, 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 SU32X180
The AirTAC Airtac SU32~50 Standard Cylinder SU32X180 is a double-acting profile-type standard cylinder with a Ø32mm bore and 180mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X180, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X180
The AirTAC SU32X180 is a discontinued double-acting profile-type cylinder with a 32mm bore and 180mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. AirTAC replaced this legacy unit with the SAU32X180 direct replacement, matching the exact body, stroke, force, and SC-series mounting footprint.
Because this SKU lacks a magnet (-S), it cannot accept a sensor. The SAU upgrade adds a built-in valve option (SAUF) this line lacked. Note that a standard cylinder drifts without live air; use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X180 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 SAU32X180 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Replacing the Airtac SU32~50 Standard Cylinder SU32X180 with the SAU32X180
To replace this discontinued SU32X180, order the SAU32X180. Verify your 1/8" port thread (PT, G, or NPT), M10x1.25 rod end, and SC-series mount (LB, FA, FB, CA, CB). Since this is a non-magnet SKU, it cannot take a sensor; if you need position detection, order an SAU32X180S and note the SAU uses current CMSG/DMSG/EMSG switches instead of legacy CS1-B/DS1-B. For loads needing 563N at 0.7MPa, step up to a 40mm bore; for lighter duty, a 25mm bore suffices. At 180mm stroke, side-load is minimal, but always guide the rod to prevent bending. The cushion only decelerates; use a pilot-operated check valve to hold loads.
Replacement checklist
- ✓ Same bore / stroke → SAU32X180
- ✓ 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 SU32X180 FAQ
Yes, the AirTAC SU32X180 is discontinued. The direct replacement is the SAU32X180. It shares the same 32mm bore, 180mm stroke, 1/8" port, and SC-series mounting accessories, so it fits the same application without modifications.
It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. This specific SKU has no magnet, so it cannot accept a sensor. If you need sensing, the SAU32X180S replacement uses CMSG/DMSG/EMSG switches.
