This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X70S, 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 SU100X70S
The AirTAC Airtac SU63-100 Standard Cylinder SU100X70S is a double-acting profile-type standard cylinder with a Ø100mm bore and 70mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X70S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X70S
The AirTAC SU100X70S is a discontinued double-acting profile-type cylinder with a 100mm bore and 70mm stroke. Delivering 3927N push force at 0.5MPa, it features an extruded aluminum barrel and adjustable cushions, making it more compact than an ISO 15552 unit of the same bore. AirTAC replaced this legacy unit with the SAU100X70S, a direct replacement retaining the exact 1/2-inch port, M20x1.5 rod thread, and SC-series mounting.
Upgrading to the SAU100X70S preserves the original body dimensions and output force, but the built-in magnet now requires modern CMSG/DMSG/EMSG switches instead of the old CS1-B/DS1-B sensors. Note that the SAU family also introduces a SAUF variant with a built-in 4M solenoid valve, an option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X70S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X70S 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). |
|---|---|
| 100 | Bore size in mm. |
| ×70 | 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 SU100X70S Is Used
Heavy Stamping Press
Drives heavy stamping dies and forming tools where the 3927N push force at 0.5MPa easily overcomes high material resistance.
Logistics Divert Arm
Actuates heavy-duty sorting arms on high-throughput conveyor lines, benefiting from the compact profile barrel to save space.
Replacing the Airtac SU63-100 Standard Cylinder SU100X70S with the SAU100X70S
To replace the SU100X70S, order the SAU100X70S, confirming the 100mm bore, 70mm stroke, 1/2-inch port (PT/G/NPT), and SC-series mounting hardware are identical. Because this SKU includes a magnet (-S), you must upgrade your legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family. If sizing alternatives, the neighboring 80mm bore yields 2513N push at 0.5MPa, while this 100mm bore reaches 5497N at 0.7MPa. A plain cylinder drifts without live air—the cushion only decelerates—so fit an external rod lock or pilot-operated check valve for held loads. For high-temperature environments up to 150C, select the Viton H seal option.
Replacement checklist
- ✓ Same bore / stroke → SAU100X70S
- ✓ 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 SU100X70S FAQ
Yes, the SU100X70S is discontinued. The direct replacement is the AirTAC SAU100X70S. It shares the same 100mm bore, 70mm stroke, 1/2-inch port, output force, and SC-series mounting, so it fits the same application directly.
At 0.5MPa it pushes 3927N and pulls 3681N; at 0.7MPa it pushes 5497N, with a theoretical max of 801kgf at 1.0MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement requires CMSG/DMSG/EMSG sensors.
