This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X1700S, 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 SU63X1700S
The AirTAC SU63-100 Standard Cylinder SU63X1700S is a double-acting profile-type standard cylinder with a Ø63mm bore and 1700mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X1700S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X1700S
The AirTAC SU63X1700S is a discontinued double-acting profile cylinder with a 63 mm bore and 1700 mm stroke. Because 1700 mm exceeds the 1500 mm standard maximum for this bore, it is a non-standard, made-to-order unit. It delivers 1559 N push force at 0.5 MPa and features a 3/8" port. AirTAC replaced the SU line with the SAU family; the SAU63X1700S is the direct replacement, matching the bore, stroke, output force, port size, and SC-series mounting.
When upgrading, note that the SAU body uses current CMSG/DMSG/EMSG sensors, whereas this legacy -S model used CS1-B/DS1-B switches. The SAU also introduces a SAUF variant with a built-in 4M solenoid valve the SU lacked. A 1700 mm stroke requires external guides 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 SAU63X1700S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 63 | 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 SU63X1700S Is Used
Long-Reach Diversion
Pushes heavy pallets across a wide conveyor belt over the full 1700 mm travel, relying on the 1559 N push force at 0.5 MPa to overcome friction.
High-Bay Extraction
Extracts totes from deep storage racks where the extended stroke is required, utilizing a safe vertical lift capacity of approximately 79 kg.
Material Transfer
Transfers automotive components between distant workstations, taking advantage of the compact profile body and 318 kgf maximum theoretical force.
Replacing the Airtac SU63-100 Standard Cylinder SU63X1700S with the SAU63X1700S
To replace this discontinued SU63X1700S, order the SAU63X1700S direct equivalent, verifying your 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this unit has the -S magnet, you must migrate from legacy CS1-B/DS1-B switches to the modern CMSG/DMSG/EMSG sensor family. If you need load holding on air loss, add an external rod lock or pilot-operated check valve, as the adjustable cushions only decelerate. This 1700 mm stroke exceeds the 1500 mm standard maximum and demands external guides to prevent rod bending. If force is insufficient, the 80 mm bore provides 2513 N push at 0.5 MPa; if excessive, the 50 mm bore offers 982 N.
Replacement checklist
- ✓ Same bore / stroke → SAU63X1700S
- ✓ 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 SU63X1700S FAQ
Yes, the SU63X1700S is discontinued. The direct replacement is the SAU63X1700S, which matches the 63 mm bore, 1700 mm stroke, 3/8" port, and SC-series mounting. The SAU body is a direct swap, though you must update your sensors.
It delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf maximum at 1.0 MPa. Because this is a -S model, it has a magnet for legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
