This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X720S, 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 SU50X720S
The AirTAC SU32~50 Standard Cylinder SU50X720S is a double-acting profile-type standard cylinder with a Ø50mm bore and 720mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X720S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X720S
The AirTAC SU50X720S is a discontinued double-acting profile-type cylinder with a 50mm bore and 720mm stroke. It delivered 982 N push and 825 N pull at 0.5 MPa through a 1/4" port. AirTAC replaced this end-of-line unit with the SAU50X720S, a direct upgrade retaining the exact body, stroke, force, and SC-series mounting footprint.
The SAU replacement modernizes sensing by switching from the legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors, and introduces the SAUF built-in 4M valve variant the SU line lacked. Note that a plain cylinder drifts on air loss; the cushion only decelerates, so use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X720S 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 SAU50X720S 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 SU50X720S Is Used
Long-Stroke Diversion
Pushes packages across a 720mm transfer lane with a safe 589 N working load, utilizing the adjustable end cushions to stop smoothly.
Multi-Station Indexing
Shifts a tooling carriage down a 720mm bed; external linear guides are mandatory here to prevent rod bending over the long stroke.
Replacing the Airtac SU32~50 Standard Cylinder SU50X720S with the SAU50X720S
To replace this discontinued SU50X720S, order the SAU50X720S. Confirm the 1/4" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) match your jig. Because this -S SKU has a magnet, you must upgrade sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG. At 0.5 MPa the 50mm bore yields 982 N push; neighbouring bores are 40mm (628 N) and 63mm (1559 N). The 720mm stroke demands external guides to prevent rod bending under side loads. For load holding on air loss, add a pilot-operated check valve or rod lock, as the cushion only decelerates. Consider the SAUF variant if you need a built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X720S
- ✓ 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 SU50X720S FAQ
Yes, the SU50X720S is discontinued. The direct replacement is the AirTAC SAU50X720S. It shares the same 50mm bore, 720mm stroke, 1/4" port, output force, and SC-series mounting. The main upgrade is that the SAU uses modern CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 50mm bore uses a 1/4" port. At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa push is 1374 N, and at 0.9 MPa it is 1767 N. The theoretical maximum force is 200 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
