This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X160STC, 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 SU32X160STC
The AirTAC SU32~50 Standard Cylinder SU32X160STC is a double-acting profile-type standard cylinder with a Ø32mm bore and 160mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X160STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X160STC
The AirTAC SU32X160STC is a discontinued double-acting profile-type cylinder with a 32 mm bore and 160 mm stroke. It delivers 402 N push force at 0.5 MPa through a 1/8" port. AirTAC replaced this unit with the SAU32X160STC, a direct replacement retaining the exact bore, stroke, output force, and SC-series TC mounting accessory.
The SAU upgrade retains the compact extruded aluminum body—shorter than an ISO 15552 equivalent—while updating the magnet for CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches. Note that the SAU family also offers a SAUF variant with a built-in valve, an option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X160STC 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 SAU32X160STC 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. |
| ×160 | 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 SU32X160STC Is Used
Small Part Ejection
Uses the 402 N push at 0.5 MPa to knock lightweight plastic or aluminum parts out of a CNC machining enclosure.
Package Diverting
Actuates a short 160 mm stroke diverter arm to push small cardboard boxes between sorting lanes.
Pneumatic Stop Gate
Functions as a compact stop gate on a roller conveyor, holding items steady using the TC mount bracket.
Replacing the Airtac SU32~50 Standard Cylinder SU32X160STC with the SAU32X160STC
To replace this discontinued SU32X160STC, order the SAU32X160STC. Verify your 1/8" port threads (PT, G, or NPT) and confirm the SC-series TC mounting fits your bracket. Because this 160 mm stroke unit has the -S magnet, you must upgrade your sensors from the old CS1-B/DS1-B to the current CMSG/DMSG/EMSG family. If you need more force, the neighboring 40 mm bore provides 628 N push at 0.5 MPa; if less is acceptable, check smaller profiles. For any load holding, remember the air cushion only decelerates the piston and a plain cylinder drifts without live air—install an external rod lock or pilot-operated check valve. At 160 mm, side loads are minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same bore / stroke → SAU32X160STC
- ✓ 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 SU32X160STC FAQ
Yes, the SU32X160STC is discontinued. The direct replacement is the AirTAC SAU32X160STC. It shares the same 32 mm bore, 160 mm stroke, 1/8" port, and TC mounting, so it drops right into the same application.
The SAU32X160STC provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa. Because your old SU used a -S magnet with CS1-B/DS1-B switches, you must upgrade to CMSG/DMSG/EMSG sensors on the SAU replacement.
