This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X540S, 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 SU63-100 Standard Cylinder SU80X540S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X540S is a double-acting profile-type standard cylinder with a Ø80mm bore and 540mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X540S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X540S
The AirTAC SU80X540S is a discontinued double-acting profile-type cylinder with an 80mm bore and 540mm stroke. The direct replacement is the SAU80X540S, matching the exact bore, stroke, 3/8" port, and SC-series mounting.
Upgrading to the SAU80X540S preserves the physical footprint and 513kgf maximum force, but the built-in magnet now pairs with current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B sensors on this SU model. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line never offered.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X540S 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 SU63-100 Standard Cylinder SU80X540S Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line using the 2513N push force at 0.5MPa, with the 540mm stroke clearing wide lane guides.
Press Ejection
Ejects formed metal parts from a press bed, utilizing the adjustable 28mm cushions to decelerate the 25mm rod smoothly at high speeds.
Replacing the Airtac SU63-100 Standard Cylinder SU80X540S with the SAU80X540S
To replace the SU80X540S, order the SAU80X540S and verify your 3/8" port threads (PT, G, or NPT) along with your SC-series mounting hardware, which remains fully compatible. Because this unit has the -S magnet, you must upgrade your position sensing from the old CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG family. If your application requires integrated flow control, consider the SAUF80 variant with its built-in valve. For sizing alternatives, dropping to a 63mm bore reduces the push force to 1559N at 0.5MPa, while staying at 80mm but increasing pressure to 0.7MPa raises push force to 3518N. Note that a standard cylinder drifts without live air—the cushions only decelerate end-of-stroke motion—so fit an external rod lock or pilot-operated check valve for load holding. Finally, with a 540mm stroke, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same bore / stroke → SAU80X540S
- ✓ 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 SU63-100 Standard Cylinder SU80X540S FAQ
Yes, the SU80X540S is discontinued. The direct replacement is the AirTAC SAU80X540S. It matches the 80mm bore, 540mm stroke, 3/8" port, output force, and SC-series mounting dimensions perfectly. You can swap it directly without altering your machine framework.
The SAU80X540S provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a maximum theoretical force of 513kgf at 1.0MPa. Because your old SU used a -S magnet with CS1-B/DS1-B switches, you must upgrade to CMSG/DMSG/EMSG sensors on the SAU replacement, as the sensor groove compatibility has changed.
