This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X390S, 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 SU80X390S
The AirTAC SU63-100 Standard Cylinder SU80X390S is a double-acting profile-type standard cylinder with a Ø80mm bore and 390mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X390S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X390S
The AirTAC SU80X390S is a discontinued double-acting profile-type cylinder with an 80mm bore and 390mm stroke. Delivering 2513 N push force at 0.5 MPa via a 3/8" port, it is directly replaced by the SAU80X390S. This direct upgrade matches the original bore, stroke, force, and SC-series mounting footprint while adding modern improvements.
The SAU replacement introduces CMSG/DMSG/EMSG sensors to succeed this model's legacy CS1-B/DS1-B switches, and offers a new SAUF built-in-valve option.

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 SAU80X390S 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 SU80X390S Is Used
Pallet Diversion
Pushes heavy pallets onto adjacent conveyor lines using the 2513 N thrust at 0.5 MPa, with the 390mm stroke clearing wide transport frames.
Press Ejection
Ejects dense metal blanks from stamping presses, utilizing the compact profile body to fit tight machine cells without tie-rod interference.
Replacing the Airtac SU63-100 Standard Cylinder SU80X390S with the SAU80X390S
To replace the SU80X390S, order the SAU80X390S direct equivalent, verifying your 3/8" port, M20x1.5 rod thread, and SC-series mounting hardware. Because this SKU includes a magnet (-S), note that your legacy CS1-B/DS1-B switches must be upgraded to the SAU's CMSG/DMSG/EMSG sensor family. If you need integrated flow control, the SAUF variant adds a built-in 4M solenoid valve the SU line lacked. When sizing, the 80mm bore yields 2513 N push at 0.5 MPa; stepping down to a 63mm bore provides 1559 N, while an 80mm bore at 0.7 MPa yields 3518 N. For the 390mm stroke, use external guides to prevent rod bending under side loads. Finally, a plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAU80X390S
- ✓ 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 SU80X390S FAQ
Yes, the SU80X390S is discontinued. The direct replacement is the SAU80X390S, which shares the identical 80mm bore, 390mm stroke, 3/8" port, output force, and SC-series mounting accessories.
The SAU80X390S provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf maximum at 1.0 MPa. Because your SU model has a magnet (-S), you must replace legacy CS1-B/DS1-B switches with the modern CMSG/DMSG/EMSG sensor family on the SAU.
