This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X170S, 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 SU32X170S
The AirTAC SU32~50 Standard Cylinder SU32X170S is a double-acting profile-type standard cylinder with a Ø32mm bore and 170mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X170S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X170S
The AirTAC SU32X170S is a discontinued double-acting profile-type cylinder with a 32mm bore and 170mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. AirTAC replaced this legacy unit with the SAU32X170S, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series mounting footprint.
The SAU upgrade modernizes sensing: your -S magnet worked with legacy CS1-B/DS1-B switches, but the SAU32X170S requires current CMSG/DMSG/EMSG sensors. The new SAU line also introduces the SAUF built-in 4M valve option, which the SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X170S 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 SAU32X170S 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 SU32X170S Is Used
Package Diverting
Deploys a 170mm stroke to actuate a routing gate on a packaging line, handling the 20kg vertical lift margin to move small cardboard boxes between belts.
Bin Push-Off
Sweeps selected inventory items from a gravity shelf into a picking tote, taking advantage of the compact 32mm profile body to fit tight rack clearances.
Replacing the Airtac SU32~50 Standard Cylinder SU32X170S with the SAU32X170S
To replace this discontinued SU32X170S, order the SAU32X170S. Verify your 1/8" port thread (PT, G, or NPT) and M10x1.25 rod-end. Because your SKU has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG on the SAU. If you need higher force, the neighboring 40mm bore provides 628N push at 0.5MPa. For load holding, note that a plain cylinder drifts on air loss—the 21mm cushions only decelerate; use an external rod lock or pilot-operated check valve to hold a load. At 170mm stroke, side-load is minimal, but ensure proper guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU32X170S
- ✓ 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 SU32X170S FAQ
Yes, the SU32X170S is discontinued. The direct replacement is the AirTAC SAU32X170S. It shares the same 32mm bore, 170mm stroke, 1/8" port, output force, and SC-series mounting accessories, so it fits the same application directly.
At 0.5MPa it provides 402N push and 345N pull force; 563N push at 0.7MPa; 724N at 0.9MPa; and a theoretical max of 82kgf at 1.0MPa. Because this is an -S model with a magnet, it used legacy CS1-B/DS1-B switches; the SAU32X170S replacement requires current CMSG/DMSG/EMSG sensors.
