This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X290S, 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 SU100X290S
The AirTAC SU63-100 Standard Cylinder SU100X290S is a double-acting profile-type standard cylinder with a Ø100mm bore and 290mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X290S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X290S
The AirTAC SU100X290S is a discontinued double-acting profile-type cylinder with a 100mm bore and 290mm stroke. It delivers 3927 N push force at 0.5 MPa, making way for the exact SAU100X290S direct replacement. The SAU retains the identical extruded aluminium body, 1/2" port, M20x1.5 rod thread and SC-series mounting, so it fits your existing setup perfectly.
Because this SU100X290S includes a piston magnet (-S), it originally used legacy CS1-B/DS1-B switches; the SAU replacement upgrades you to current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF built-in 4M solenoid valve option the SU never had. Note that a plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X290S 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 SAU100X290S 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 SU100X290S Is Used
Heavy Press Clamping
Ideal for securing heavy steel plates during machining, using the 3927 N push force at 0.5 MPa to hold components rigidly in place.
Pallet Lift Gates
Drives robust 200 kg vertical lifting gates on loading docks, providing reliable kinetic energy transfer with its 290mm stroke.
Industrial Door Actuation
Moves large automated factory doors, taking advantage of the compact profile body and 1/2" port for high-volume airflow.
Replacing the Airtac SU63-100 Standard Cylinder SU100X290S with the SAU100X290S
To replace this SU100X290S, order the SAU100X290S. Verify your 1/2" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) to ensure a direct fit. Because this is an -S magnet model, you must replace legacy CS1-B/DS1-B switches with CMSG/DMSG/EMSG sensors. If you need integrated airflow control, consider the SAUF variant with its built-in valve. At 290mm stroke, guide your load to prevent rod bending and side-load wear. Sizing both ways: dropping to an 80mm bore yields 2513 N push at 0.5 MPa, while staying at 100mm gives 5497 N at 0.7 MPa. Remember, the adjustable cushion only decelerates; it does not hold the load on air loss, so add a pilot-operated check valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU100X290S
- ✓ 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 SU100X290S FAQ
Yes, the SU100X290S is discontinued. The direct replacement is the SAU100X290S. It shares the same 100mm bore, 290mm stroke, output force, 1/2" port, and SC-series mounting, so it fits the same application without modifications.
The 100mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a max force of 801 kgf at 1.0 MPa. Because this is an -S model, the legacy CS1-B/DS1-B switches must be upgraded to CMSG/DMSG/EMSG sensors on the SAU replacement.
