This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X1800S, 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 SU63X1800S
The AirTAC SU63-100 Standard Cylinder SU63X1800S is a double-acting profile-type standard cylinder with a Ø63mm bore and 1800mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X1800S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X1800S
The AirTAC SU63X1800S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 1800 mm stroke. It delivers 1559 N push force at 0.5 MPa via a 3/8 inch port. Because 1800 mm exceeds the 1500 mm standard maximum for this bore, it is a non-standard, made-to-order length. AirTAC replaced the SU line with the SAU family, making the SAU63X1800S the direct upgrade: identical body, stroke, force, port, and SC-series mounting.
When migrating to the SAU63X1800S, note that the -S piston magnet now pairs with current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B sensors. The new SAUF variant also adds a built-in 4M solenoid valve the SU lacked. At 1800 mm, an external guide is mandatory to prevent rod bending under side loads.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X1800S 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 SU63X1800S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets 1.8 meters between conveyor zones using 1559 N of thrust at 0.5 MPa, requiring external guides to stabilize the extended rod.
High-Bay Storage Extraction
Extracts totes from deep shelving racks where the compact profile body saves axial space compared to standard ISO cylinders of the same bore.
Large Panel Indexing
Shifts wide fabrication panels across machining stations, utilizing the 318 kgf maximum theoretical force for heavy-duty positioning cycles.
Replacing the Airtac SU63-100 Standard Cylinder SU63X1800S with the SAU63X1800S
To replace the SU63X1800S, order the SAU63X1800S direct equivalent, verifying the 3/8 inch port, M16x1.5 rod thread, and SC-series mounting hardware. If sizing alternatives, the adjacent 50 mm bore yields 982 N push at 0.5 MPa, while the 80 mm bore provides 2513 N, allowing you to step up or down based on your exact force needs. Because this 1800 mm stroke exceeds the 1500 mm standard maximum, expect a made-to-order lead time and ensure external linear guides support the rod to prevent bending over this long distance. The -S magnet requires switching to CMSG/DMSG/EMSG sensors on the SAU body. Finally, a plain cylinder drifts on air loss—the cushion only decelerates—so install an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAU63X1800S
- ✓ 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 SU63X1800S FAQ
Yes, the SU63X1800S is discontinued. The direct replacement is the AirTAC SAU63X1800S. It shares the same 63 mm bore, 1800 mm stroke, 3/8 inch port, output force, and SC-series mounting, so it fits the same application directly.
At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa it pushes 2182 N, with a 318 kgf theoretical max at 1.0 MPa. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades this to CMSG/DMSG/EMSG sensors.
