This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X150, 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 SU32X150
The AirTAC Airtac SU32~50 Standard Cylinder SU32X150 is a double-acting profile-type standard cylinder with a Ø32mm bore and 150mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X150, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X150
The AirTAC SU32X150 is a discontinued double-acting profile-type cylinder with a 32mm bore and 150mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. AirTAC replaced this unit with the SAU32X150, a direct upgrade retaining the exact bore, stroke, force, port size and SC-series mounting.
The SAU upgrade modernizes sensing to CMSG/DMSG/EMSG switches, though this specific non-magnet SKU cannot accept any sensor. The SAU family also adds a SAUF valve-integrated option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X150 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 SAU32X150 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 SU32X150 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight molded parts out of an injection press fixture.
Package Diverting
Actuates a routing gate on a packaging line, where the compact profile body saves space compared to standard ISO cylinders.
Stopper Cylinder
Functions as a pneumatic stop for small totes on a roller conveyor, safely handling loads up to the 20kg vertical lift limit.
Replacing the Airtac SU32~50 Standard Cylinder SU32X150 with the SAU32X150
To replace this SU32X150, order the SAU32X150. Verify your 1/8" port, M10x1.25 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) which all carry over directly. This non-magnet SKU cannot accept a sensor; if position detection is needed, order an SAU32X150-S and migrate to CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B. At 150mm stroke, side-load is minimal, but ensure adequate guiding for the 12mm rod. If stepping up to a 40mm bore, thrust jumps to 628N at 0.5MPa. Note that a plain cylinder drifts on air loss; the 21mm cushions only decelerate near stroke ends. For held loads, add an external rod lock or pilot-operated check valve. The SAUF variant offers a built-in valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU32X150
- ✓ 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 SU32X150 FAQ
Yes, the SU32X150 is discontinued. The direct replacement is the AirTAC SAU32X150. It shares the identical 32mm bore, 150mm stroke, 402N force, 1/8" port, and SC-series mounting, so it drops directly into the same application.
The 32mm bore yields 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. Because this specific SKU lacks a magnet (-S), it cannot accept any sensor. The SAU replacement with a magnet uses modern CMSG/DMSG/EMSG switches.
