This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X850, 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 SU32X850
The AirTAC Airtac SU32~50 Standard Cylinder SU32X850 is a double-acting profile-type standard cylinder with a Ø32mm bore and 850mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X850, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X850
The AirTAC SU32X850 is a discontinued double-acting profile-type cylinder featuring an 850 mm stroke and a 32 mm bore. It delivers 402 N push force at 0.5 MPa through a 1/8" port. AirTAC replaced this legacy unit with the SAU32X850, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore.
This non-magnet SKU cannot accept a sensor. The SAU upgrade switches to current CMSG/DMSG/EMSG switches (legacy used CS1-B/DS1-B) and adds a SAUF built-in valve option. Note this 850 mm stroke exceeds the 500 mm standard, requiring external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X850 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 SAU32X850 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 SU32X850 Is Used
Extended Stroke Diversion
Pushes light packages across a transfer lane with its 850 mm reach, sized safely under the 241 N working load limit.
High-Bay Ejection
Ejects small totes from deep storage racking where a compact 32 mm profile body saves valuable machine footprint.
Long-Reach Part Pushing
Transfers lightweight machined components between stations, requiring external guide rails to support the long rod.
Replacing the Airtac SU32~50 Standard Cylinder SU32X850 with the SAU32X850
To replace this discontinued SU32X850, order the SAU32X850 direct equivalent, verifying your 1/8" port, M10x1.25 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this 850 mm stroke exceeds the 32 mm bore standard maximum of 500 mm, it is a nonstandard stroke—external guides are mandatory to prevent rod bending and side-load damage. If sizing downward, a 40 mm bore offers 628 N push at 0.5 MPa; sizing upward is unnecessary if 402 N suffices. This non-magnet SKU cannot take a sensor, but if you need position detection on the SAU, specify the -S option and migrate to CMSG/DMSG/EMSG switches (the SU used CS1-B/DS1-B). The cushion only decelerates; use an external rod lock or pilot-operated check valve to hold loads. The SAUF variant offers a built-in 4M valve if desired.
Replacement checklist
- ✓ Same bore / stroke → SAU32X850
- ✓ 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 SU32X850 FAQ
Yes, the SU32X850 is discontinued. The direct replacement is the SAU32X850, which matches the 32 mm bore, 850 mm stroke, 402 N force, 1/8" port, and SC-series mounting. You simply order the SAU32X850.
It delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot accept a sensor. If sensing is needed on the SAU replacement, order the -S option and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
