This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X759, 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 SU80X759
The AirTAC Airtac SU63-100 Standard Cylinder SU80X759 is a double-acting profile-type standard cylinder with a Ø80mm bore and 759mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X759, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X759
The AirTAC SU80X759 is a discontinued double-acting profile-type cylinder featuring an extruded aluminum barrel and adjustable air cushions at both ends. Delivering 2513 N push force at 0.5 MPa, its direct replacement is the SAU80X759, which preserves the 80 mm bore, 759 mm stroke, 3/8" port, and SC-series mounting compatibility.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a SAUF built-in-valve option the SU lacked. Note this non-magnetic SKU cannot accept a sensor, and the 759 mm stroke requires external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X759 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAU80X759 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 SU80X759 Is Used
Press Ejection
Cycles at 30-800 mm/s to eject parts, with adjustable 28 mm cushions decelerating the rod at both ends.
Replacing the Airtac SU63-100 Standard Cylinder SU80X759 with the SAU80X759
To replace the SU80X759, order the SAU80X759. Verify your 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this is a non-magnetic SKU, it cannot accept a sensor; if sensing is needed, specify an SAU-S model and upgrade to CMSG/DMSG/EMSG switches (the SU used legacy CS1-B/DS1-B). For sizing both ways: dropping to a 63 mm bore gives 1559 N push at 0.5 MPa, while an 80 mm bore yields 3518 N at 0.7 MPa. At 759 mm stroke, use external guides to prevent rod bending under side loads. The cylinder does not hold load on air loss—use an external rod lock or pilot-operated check valve. The SAUF variant adds a built-in 4M valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU80X759
- ✓ 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 SU80X759 FAQ
Yes, the AirTAC SU80X759 is discontinued. The direct replacement is the SAU80X759. It matches the 80 mm bore, 759 mm stroke, 2513 N force, 3/8" port, and SC-series mounting. The SAU also offers a SAUF built-in-valve option the SU lacked.
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa it pushes 3518 N, 4523 N at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa. This non-magnetic SKU cannot take a sensor; the SAU-S replacement uses CMSG/DMSG/EMSG switches.
