This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X1700S, 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 SU80X1700S
The AirTAC SU63-100 Standard Cylinder SU80X1700S 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 SAU80X1700S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X1700S
The AirTAC SU80X1700S is a discontinued double-acting profile-type cylinder with an 80mm bore and a 1700mm stroke. Because 1700mm exceeds the 1500mm standard maximum for this bore, it is a non-standard, made-to-order unit. It delivers 2513N push force at 0.5MPa via a 3/8" port. AirTAC replaced the SU line with the SAU family; the direct replacement is the SAU80X1700S, matching the bore, stroke, force, port and SC-series mounting.
The SAU upgrade keeps the compact extruded aluminum body but switches the -S magnet sensor compatibility from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. It also introduces the SAUF variant with a built-in 4M solenoid valve, which the SU line lacked. Note that a plain cylinder drifts without live air; use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X1700S 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 SAU80X1700S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU80X1700S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×1700 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU80X1700S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets 1700mm between conveyor lines using 2513N of thrust at 0.5MPa, requiring external guide rails to support 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 80mm bore.
Replacing the Airtac SU63-100 Standard Cylinder SU80X1700S with the SAU80X1700S
To replace this discontinued SU80X1700S, order the SAU80X1700S direct equivalent. Confirm the 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because the -S magnet is present, you must upgrade your sensors: the old CS1-B/DS1-B switches will not fit the SAU, so select CMSG/DMSG/EMSG sensors. This 1700mm stroke is non-standard (exceeding the 1500mm max) and requires external guides to prevent rod bending under side loads. If checking neighbouring bores, a 63mm bore yields 1559N push while a 100mm bore yields 3927N at 0.5MPa. The air cushion only decelerates the piston; it does not lock the load, so add a pilot-operated check valve for vertical holding. The SAUF valve-integrated option can simplify cycling if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU80X1700S
- ✓ 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 SU80X1700S FAQ
Yes, the SU80X1700S is discontinued. The direct replacement is the SAU80X1700S. It matches the 80mm bore, 1700mm stroke, 3/8" port, output force, and SC-series mounting accessories. You can swap it directly without changing your mechanical setup.
At 0.5MPa it pushes 2513N and pulls 2268N; at 0.7MPa it pushes 3518N, and the theoretical max is 513kgf at 1.0MPa. Because this is an -S magnet model, note that the old CS1-B/DS1-B switches are obsolete; the SAU replacement requires CMSG/DMSG/EMSG sensors.
