This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X720S, 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 SU80X720S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X720S is a double-acting profile-type standard cylinder with a Ø80mm bore and 720mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X720S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X720S
The AirTAC SU80X720S is a discontinued double-acting profile-type cylinder with an 80mm bore and 720mm stroke. The direct replacement is the SAU80X720S, matching the 3/8" port, M20x1.5 rod thread, and 513kgf max force.
Because the 720mm stroke exceeds 300mm, use external guides to prevent rod bending under side loads. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore, reusing AirTAC SC-series mounts. The -S magnet on this unit worked with legacy CS1-B/DS1-B switches, but the SAU replacement uses current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF valve-integrated option the SU lacked.

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 SAU80X720S 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 SU80X720S Is Used
Long-Stroke Diversion
Pushes heavy pallets laterally across a transfer line using the 720mm stroke and 2513N push force at 0.5MPa.
Heavy Blank Stacking
Lifts steel blanks from a magazine, relying on the 80mm bore's 513kgf maximum theoretical force for robust handling.
Replacing the Airtac SU63-100 Standard Cylinder SU80X720S with the SAU80X720S
To replace this SU80X720S with the SAU80X720S, verify the 80mm bore, 720mm stroke, 3/8" port, and SC-series mounting hardware. If sizing alternatives, the neighboring 63mm bore provides 1559N push at 0.5MPa, while the 100mm bore offers 3927N. For the 720mm stroke, external guides are mandatory to prevent rod-bending side loads. The -S magnet means you must upgrade sensors from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG on the SAU. A plain cylinder drifts without live air, so add an external rod lock or pilot-operated check valve for load holding. For faster cycling, consider the SAUF variant with its built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X720S
- ✓ 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 SU80X720S FAQ
Yes, the AirTAC SU80X720S is discontinued. The direct replacement is the SAU80X720S. It matches the 80mm bore, 720mm stroke, 3/8" port, output force, and SC-series mounting. You simply order the SAU equivalent.
The 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf max at 1.0MPa. Because your SU has the -S magnet for legacy CS1-B/DS1-B switches, you must upgrade to CMSG/DMSG/EMSG sensors on the SAU replacement.
