This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X800STC, 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 SU32X800STC
The AirTAC Airtac SU32~50 Standard Cylinder SU32X800STC is a double-acting profile-type standard cylinder with a Ø32mm bore and 800mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X800STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X800STC
The AirTAC SU32X800STC is a discontinued double-acting profile-type cylinder with a 32 mm bore and 800 mm stroke. Delivering 402 N push force at 0.5 MPa, it features a compact extruded aluminum body shorter than an ISO 15552 cylinder of the same bore. AirTAC replaced this unit with the SAU32X800STC, a direct replacement retaining the exact bore, stroke, output force, 1/8" port, and SC-series TC mounting interface.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used on this -S SKU. Additionally, the SAU line offers a SAUF variant with a built-in 4M solenoid valve, an option the original SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X800STC 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 SAU32X800STC 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 SU32X800STC Is Used
Vertical Material Lift
Raises lightweight totes up to 20 kg in a pick module, taking advantage of the compact 32 mm profile body to fit within tight vertical elevator shafts.
Sensor-Driven Gating
Actuates safety gates on an assembly line, relying on the TC mount and piston magnet for position feedback to sequence automated tooling.
Replacing the Airtac SU32~50 Standard Cylinder SU32X800STC with the SAU32X800STC
To replace the SU32X800STC, order the SAU32X800STC. Verify the 32 mm bore, 800 mm stroke, 1/8" port, and M10x1.25 rod thread. This SKU uses TC mounting, an SC-series accessory. Because it has an 800 mm stroke, prevent rod bending by ensuring external guides handle side loads. If moving loads vertically, note that a plain cylinder drifts without live air; the 21 mm adjustable cushions only decelerate at stroke ends. Use an external rod lock or pilot-operated check valve for secure holding. The -S magnet means you must switch to CMSG/DMSG/EMSG sensors for the SAU. If you need higher force, the neighboring 40 mm bore provides 628 N push at 0.5 MPa.
Replacement checklist
- ✓ Same bore / stroke → SAU32X800STC
- ✓ 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 SU32X800STC FAQ
Yes, the SU32X800STC is discontinued. The direct replacement is the AirTAC SAU32X800STC. It shares the identical 32 mm bore, 800 mm stroke, 402 N force at 0.5 MPa, 1/8" port, and SC-series TC mounting, so it fits the same application directly.
At 0.5 MPa it provides 402 N push and 345 N pull force, increasing to 563 N at 0.7 MPa, with a theoretical max of 82 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches do not carry over; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
