This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X180S, 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 SU32X180S
The AirTAC SU32~50 Standard Cylinder SU32X180S 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 SAU32X180S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X180S
The AirTAC SU32X180S is a discontinued double-acting profile-type cylinder with a 32mm bore and 180mm stroke, delivering 402N push force at 0.5 MPa. AirTAC replaced this unit with the SAU32X180S, a direct alternative retaining the exact 1/8" port, M10x1.25 rod thread, and SC-series mounting footprint.
The SAU upgrade keeps the body geometry but shifts sensors from the legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG family. Note that the air cushion only decelerates the load; an external rod lock is required to hold position.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X180S 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 SAU32X180S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×180 | 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 SU32X180S Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture on an automated lathe, utilizing the 402N push force at 0.5 MPa.
Package Diverting
Actuates a short-stroke diverter arm on a conveyor belt to sort small parcels, benefiting from the compact 32mm profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU32X180S with the SAU32X180S
To replace the SU32X180S, order the SAU32X180S and confirm your 1/8" port thread (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, TC). Because this unit has the -S magnet, you must upgrade your position sensing from the old CS1-B/DS1-B reed switches to the SAU's CMSG/DMSG/EMSG electronic sensors. If your application needs a self-switching function, the SAU line offers the SAUF variant with a built-in 4M solenoid valve, a feature the SU series lacked. If you need more force, stepping up to a 40mm bore yields 628N push at 0.5 MPa; if you need less, a 25mm bore (if available) or lowering the pressure is advised. For this 180mm stroke, side-load and rod-bending stresses are minimal, but always ensure proper guide alignment to prevent seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAU32X180S
- ✓ 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 SU32X180S FAQ
Yes, the SU32X180S is discontinued. The direct replacement is the AirTAC SAU32X180S. It shares the same 32mm bore, 180mm stroke, output force, 1/8" port size, and SC-series mounting accessories, so it fits the same application without mechanical modifications.
The cylinder provides 402N push and 345N pull at 0.5 MPa, 563N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Because your original SU model has an -S magnet, note that the SAU replacement requires upgrading from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family.
