This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X600, 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 SU50X600
The AirTAC SU32~50 Standard Cylinder SU50X600 is a double-acting profile-type standard cylinder with a Ø50mm bore and 600mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X600, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X600
The AirTAC SU50X600 is a discontinued double-acting profile-type cylinder featuring a 50mm bore and 600mm stroke. It delivers 982N push force at 0.5MPa via a 1/4" port, making it a robust choice for mid-range automation. AirTAC replaced this legacy unit with the SAU50X600, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
The SAU replacement modernizes sensing by adopting CMSG/DMSG/EMSG switches instead of the SU's older CS1-B/DS1-B, and introduces the SAUF built-in 4M valve variant. Note this SKU lacks a magnet and cannot accept sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X600 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAU50X600 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SU32~50 Standard Cylinder SU50X600 Is Used
Long-Stroke Diversion
Pushes packages across transfer lanes using the 600mm reach, relying on the 982N thrust at 0.5MPa to overcome guide friction.
Multi-Stage Ejection
Cycles molded parts out of a press area over 600mm, using adjustable end cushions to decelerate the moving payload.
Replacing the Airtac SU32~50 Standard Cylinder SU50X600 with the SAU50X600
To replace the SU50X600, order the SAU50X600, confirming the 1/4" port, M16x1.5 rod thread, and PT/G/NPT thread type. Because this is a 600mm stroke, prevent rod bending by adding external guides to manage side loads. If sizing alternatives, the neighbouring 40mm bore yields 628N push at 0.5MPa, while the 63mm bore yields 1559N. A plain cylinder drifts on air loss—the 21mm cushions only decelerate the end-of-stroke—so fit an external rod lock or pilot-operated check valve for held loads. The SAUF valve-integrated option can simplify actuation if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X600
- ✓ 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 SU50X600 FAQ
Yes, the SU50X600 is discontinued. The direct replacement is the AirTAC SAU50X600. It matches the 50mm bore, 600mm stroke, 1/4" port, force output, and SC-series mounting, fitting the same application.
It delivers 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a 200kgf max at 1.0MPa. This specific SKU has no magnet and cannot take sensors. The SAU replacement uses CMSG/DMSG/EMSG switches.
