This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X235S, 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 SU100X235S
The AirTAC SU63-100 Standard Cylinder SU100X235S is a double-acting profile-type standard cylinder with a Ø100mm bore and 235mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X235S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X235S
The AirTAC SU100X235S is a discontinued double-acting profile-type cylinder with a 100mm bore and 235mm stroke. As a non-standard stroke length, it delivered 3927N push and 3681N pull at 0.5MPa. AirTAC replaced this end-of-line unit with the SAU100X235S. This direct upgrade matches the original 1/2" port, M20x1.5 rod thread, output force, and SC-series mounting accessories.
The SAU body is shorter than an ISO 15552 cylinder of the same bore. The -S magnet on this legacy SKU worked with CS1-B/DS1-B switches; the SAU replacement uses modern CMSG/DMSG/EMSG sensors, and the SAUF variant adds a built-in valve the SU lacked.

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 SAU100X235S 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 SU100X235S Is Used
Heavy Press Operations
Drives forming and stamping presses requiring up to 3927N of push force at 0.5MPa, utilizing the 100mm bore for high-thrust metalworking tasks.
Pallet Handling
Indexes heavy loaded pallets along conveyors, where the 235mm stroke provides the precise extension needed to push or lift substantial weights safely.
Automated Assembly Clamping
Secures large automotive or industrial components during machining, relying on the robust 25mm piston rod and adjustable 29mm cushions to absorb shock.
Replacing the Airtac SU63-100 Standard Cylinder SU100X235S with the SAU100X235S
To replace the SU100X235S, order the SAU100X235S, confirming the 100mm bore, 235mm non-standard stroke, 1/2" port, and PT/G/NPT thread. Reuse your SC-series mounts. Because this is a non-standard 235mm stroke, verify the exact extended length. If sizing alternatives, a 80mm bore gives 2513N push at 0.5MPa, while a 100mm bore yields 5497N at 0.7MPa. Since the 235mm stroke is under 300mm, side-load rod-bending risk is moderate, but guides are still recommended. The -S magnet requires a sensor family change from CS1-B/DS1-B to CMSG/DMSG/EMSG. A plain cylinder drifts without live air; use an external rod lock or pilot-operated check valve for held loads. For faster cycling, consider the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU100X235S
- ✓ 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 SU100X235S FAQ
Yes, the AirTAC SU100X235S is discontinued. The direct replacement is the SAU100X235S. It shares the same 100mm bore, 235mm stroke, 1/2" 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. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades this to CMSG/DMSG/EMSG sensors.
