This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X175S, 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 SU32X175S
The AirTAC SU32~50 Standard Cylinder SU32X175S 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 SAU32X175S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X175S
The AirTAC SU32X175S is a discontinued double-acting profile-type cylinder with a 32mm bore and 175mm stroke. It delivers 402N push and 345N pull at 0.5MPa via a 1/8" port. AirTAC replaced this unit with the SAU32X175S, a direct upgrade retaining the exact bore, stroke, force, and SC-series mounting footprint.
This compact extruded-aluminium body is shorter than an ISO 15552 equivalent. The SAU upgrade switches the legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors and adds the SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X175S 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 SAU32X175S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU32~50 Standard Cylinder SU32X175S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×175 | 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 SU32X175S Is Used
Small Part Ejection
Uses the 402N push at 0.5MPa to reliably knock lightweight machined components out of a fixture.
Package Diverting
Actuates a routing gate along a packaging line, safely handling loads under the 20kg vertical limit.
Clamp Actuation
Secures small sub-assemblies during secondary machining with a compact 32mm profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU32X175S with the SAU32X175S
To replace this discontinued SU32X175S, order the SAU32X175S. Verify your 1/8" port, M10x1.25 rod thread, and SC-series mounts. Because this SKU has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If you need more force, the 40mm bore yields 628N push at 0.5MPa; if less is acceptable, consider a smaller unit. For stroke lengths like 175mm, guide external rods to prevent side-loading. A plain cylinder drifts on air loss—the 21mm cushions only decelerate—so add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAU32X175S
- ✓ 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 SU32X175S FAQ
Yes, the SU32X175S is discontinued. The direct replacement is the SAU32X175S. It matches the 32mm bore, 175mm stroke, 1/8" port, output force, and SC-series mounting accessories, so no mechanical changes are needed.
The 32mm bore yields 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a max of 82kgf at 1.0MPa. Because this is the -S magnet version, the old CS1-B/DS1-B switches are obsolete; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
