This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X600STC, 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 SU50X600STC
The AirTAC SU32~50 Standard Cylinder SU50X600STC 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 SAU50X600STC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X600STC
The AirTAC SU50X600STC is a discontinued double-acting profile-type cylinder with a 50mm bore and 600mm stroke. It delivers 982N push and 825N pull at 0.5MPa via a 1/4 port. AirTAC replaced this unit with the SAU50X600STC, a direct upgrade retaining the exact body, M16x1.5 rod, and TC mounting interface.
When migrating to the SAU50X600STC, your physical footprint and 982N thrust remain identical, but the legacy CS1-B/DS1-B switches are replaced by modern CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF built-in-valve variant absent in the SU era.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X600STC 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 SAU50X600STC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 SU50X600STC Is Used
Long-Stroke Diversion
Drives 600mm routing gates on packaging lines, utilizing the 982N thrust to push heavy cardboard flats smoothly onto auxiliary tracks.
Component Ejection
Clears machined metal parts from CNC work areas over a 600mm distance, relying on adjustable end cushions to decelerate the 20mm rod safely.
Replacing the Airtac SU32~50 Standard Cylinder SU50X600STC with the SAU50X600STC
To replace the SU50X600STC, order the SAU50X600STC and verify your 1/4 port threads (PT/G/NPT) along with the TC mounting hardware. Because this SKU includes a magnet (-S), note that your old CS1-B/DS1-B switches must be swapped for CMSG/DMSG/EMSG sensors on the new cylinder. For load holding, remember that a standard cylinder drifts without live air; the cushions only decelerate, so add an external rod lock or pilot-operated check valve if needed. At 600mm stroke, prevent rod bending by guiding the load externally to avoid side-load forces. If downsizing, a 40mm bore yields 628N push; if upsizing, a 63mm bore provides 1559N.
Replacement checklist
- ✓ Same bore / stroke → SAU50X600STC
- ✓ 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 SU50X600STC FAQ
Yes, the SU50X600STC is discontinued. The direct replacement is the AirTAC SAU50X600STC. It matches the 50mm bore, 600mm stroke, 982N force, 1/4 port, and TC mounting, so it drops right into the same application.
The 50mm bore provides 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a 200kgf max at 1.0MPa. Because this is an -S magnet model, the old CS1-B/DS1-B switches are obsolete; the SAU replacement requires CMSG/DMSG/EMSG sensors.
