This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X65S, 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 SU100X65S
The AirTAC Airtac SU63-100 Standard Cylinder SU100X65S is a double-acting profile-type standard cylinder with a Ø100mm bore and 65mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X65S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X65S
The AirTAC SU100X65S is a discontinued double-acting profile-type cylinder with a 100mm bore and 65mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 unit of the same size. It delivers a robust 3927 N push force at 0.5 MPa. AirTAC replaced this end-of-line unit with the SAU100X65S, a direct replacement retaining the exact 1/2" port, M20x1.5 rod thread, and SC-series mounting compatibility.
When migrating to the SAU100X65S, your body dimensions, force output, and 29mm adjustable cushions remain identical. Note that this -S SKU relied on legacy CS1-B/DS1-B sensors; the SAU successor requires current CMSG/DMSG/EMSG switches. Furthermore, the SAU line introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X65S 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 SAU100X65S 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. |
| ×65 | 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 SU100X65S Is Used
Heavy Pressing Operations
Drives heavy-duty stamping and forming presses where the 3927 N push at 0.5 MPa is required to seat or deform substantial metal components securely.
Pallet Load Shifting
Indexes loaded pallets on heavy-duty conveyors, utilizing the 200 kg safe vertical lift capacity to elevate and transfer goods efficiently between zones.
Mold Clamping Stations
Holds large injection molds or industrial fixtures in place during processing, benefiting from the rigid 25mm piston rod and compact profile barrel.
Replacing the Airtac SU63-100 Standard Cylinder SU100X65S with the SAU100X65S
To replace the discontinued SU100X65S, order the SAU100X65S, verifying your 1/2" port, M20x1.5 rod thread, and SC-series mounting hardware (LB, FA, FB, CA, CB, TC). Because this is a -S model, you must account for the sensor family change: the old CS1-B/DS1-B switches are obsolete, so you will need CMSG/DMSG/EMSG sensors for the SAU groove. If your application requires load holding during air loss, note that neither the SU nor the SAU acts as a lock; the 29mm cushions only decelerate the piston near the ends, so you must fit an external rod lock or pilot-operated check valve. For sizing alternatives, dropping to an 80mm bore reduces the 0.5 MPa push to 2513 N, while staying at 100mm yields a massive 801 kgf at 1.0 MPa. If you want to simplify plumbing, explore the SAUF100 model which integrates a valve directly on the body.
Replacement checklist
- ✓ Same bore / stroke → SAU100X65S
- ✓ 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 SU100X65S FAQ
Yes, the AirTAC SU100X65S is discontinued and end-of-life. The direct replacement is the SAU100X65S. It features the same 100mm bore, 65mm stroke, 1/2" port, output force, and SC-series mounting accessories, meaning it fits the exact same application footprint without modification.
The 100mm bore provides a push of 3927 N and pull of 3681 N at 0.5 MPa, 5497 N push at 0.7 MPa, and a maximum theoretical force of 801 kgf at 1.0 MPa. Because this is an -S magnet model, it originally used legacy CS1-B/DS1-B switches. The SAU100X65S replacement requires upgrading to the current CMSG/DMSG/EMSG sensor family.
