This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X175, 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 SU32X175
The AirTAC Airtac SU32~50 Standard Cylinder SU32X175 is a double-acting profile-type standard cylinder with a Ø32mm bore and 175mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X175, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X175
The AirTAC SU32X175 is a discontinued double-acting profile-type cylinder with a 32 mm bore and 175 mm stroke. It delivers 402 N push force at 0.5 MPa through a 1/8" port. AirTAC replaced this with the SAU32X175, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent. Note this non-magnet SKU cannot hold a load without live air, and the SAU upgrade switches sensors from legacy CS1-B to CMSG.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X175 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 SAU32X175 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 SU32X175 Is Used
Small Part Ejection
Uses the 402 N push at 0.5 MPa to eject light machined components from a fixture cleanly over the 175 mm travel.
Gate Actuation
Cycles lightweight sorting gates where the compact 32 mm profile body saves space compared to standard ISO cylinders.
Replacing the Airtac SU32~50 Standard Cylinder SU32X175 with the SAU32X175
To replace this discontinued SU32X175, order the SAU32X175. Verify your 1/8" port, M10x1.25 rod thread, and SC-series mounting. This non-magnet SKU cannot accept a sensor; if you need position detection, the SAU upgrade uses modern CMSG/DMSG/EMSG switches. For sizing, a 40 mm bore offers 628 N push at 0.5 MPa if you need more force. The 175 mm stroke is under the 1000 mm standard limit, but always guide the rod to prevent side-load bending. The cylinder will not hold a load on air loss—use an external rod lock. The SAUF variant adds a built-in valve the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU32X175
- ✓ 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 SU32X175 FAQ
Yes, the AirTAC SU32X175 is discontinued. The direct replacement is the SAU32X175. It matches the 32 mm bore, 175 mm stroke, 402 N force, 1/8" port, and SC-series mounting, so it fits the same application.
It provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a max of 82 kgf at 1.0 MPa. This specific non-magnet SKU cannot accept a sensor. If sensing is needed, the SAU replacement supports CMSG/DMSG/EMSG switches.
