This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X1700, 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 SU80X1700
The AirTAC SU63-100 Standard Cylinder SU80X1700 is a double-acting profile-type standard cylinder with a Ø80mm bore and 1700mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X1700, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X1700
The AirTAC SU80X1700 is a discontinued double-acting profile-type cylinder with an 80 mm bore and a 1700 mm stroke. Because 1700 mm exceeds the 1500 mm standard maximum for this bore, it is a non-standard, made-to-order size. This legacy unit delivered 2513 N of push force and 2268 N of pull force at 0.5 MPa. AirTAC replaced the SU line with the SAU family, making the SAU80X1700 the direct replacement. It retains the exact same extruded aluminium body, 3/8" port, M20x1.5 rod thread, and SC-series mounting compatibility.
When upgrading, note that the SAU80X1700 uses current CMSG, DMSG, or EMSG sensors, whereas this older SU had no magnet and cannot accept any switch. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X1700 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 SAU80X1700 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 SU80X1700 Is Used
Long-Reach Diversion
Pushes heavy pallets across wide sorting lines over the full 1700 mm extension, relying on the 2513 N thrust to overcome friction without stalling.
High-Bay Extraction
Extracts totes from deep storage racking where the compact profile body saves axial space compared to standard ISO cylinders of the same 80 mm bore.
Material Ejection
Cycles molded parts out of large presses, using the adjustable 28 mm air cushions to decelerate the payload smoothly at the end of the long travel.
Replacing the Airtac SU63-100 Standard Cylinder SU80X1700 with the SAU80X1700
To replace the discontinued SU80X1700, order the SAU80X1700 direct equivalent, confirming the 80 mm bore, 1700 mm non-standard stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB, FA, FB, CA, CB). Because this SKU lacks a magnet (-S), it cannot support sensing; if you need position detection on the SAU, specify the -S option and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. Sizing both ways: a 63 mm bore gives 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. Remember that a standard cylinder drifts without live air—the 28 mm cushions only decelerate near stroke end, so use an external rod lock or pilot-operated check valve for load holding. Finally, at 1700 mm, the Ø25 mm rod is highly susceptible to bending; use external guides to prevent side-load damage.
Replacement checklist
- ✓ Same bore / stroke → SAU80X1700
- ✓ 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 SU80X1700 FAQ
Yes, the SU80X1700 is discontinued. The direct replacement is the SAU80X1700. It matches the 80 mm bore, 1700 mm stroke, 2513 N output force at 0.5 MPa, 3/8" port, and SC-series mounting accessories, fitting the exact same application.
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa it pushes 3518 N, and the theoretical maximum is 513 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot accept a sensor; the SAU replacement with a -S option uses CMSG/DMSG/EMSG switches.
