This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X320S, 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 SU100X320S
The AirTAC Airtac SU63-100 Standard Cylinder SU100X320S is a double-acting profile-type standard cylinder with a Ø100mm bore and 320mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X320S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X320S
The AirTAC SU100X320S is a discontinued double-acting profile-type cylinder with a 100 mm bore and 320 mm stroke. It delivers a push force of 3927 N at 0.5 MPa (7068 N at 0.9 MPa) and features a 1/2" port with an M20x1.5 rod thread. AirTAC replaced this legacy unit with the SAU100X320S, a direct replacement retaining the exact same body profile, force output, port size, and SC-series mounting accessories.
Because this SKU includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches; the SAU successor upgrades to current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X320S 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 SAU100X320S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×320 | 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 SU100X320S Is Used
Heavy Stamp Pressing
Drives large stamping dies requiring substantial push force, utilizing the 3927 N at 0.5 MPa to form thick metal components reliably.
Pallet Lifting
Raises loaded pallets up to 200 kg in vertical lift scenarios, benefiting from the 320 mm stroke to clear conveyor heights safely.
Bulk Material Diversion
Actuates heavy-duty routing gates on high-capacity packaging lines, where the 1/2" port ensures rapid 30-800 mm/s cycling.
Replacing the Airtac SU63-100 Standard Cylinder SU100X320S with the SAU100X320S
To replace the discontinued SU100X320S, order the SAU100X320S and verify your bore (100 mm), stroke (320 mm), 1/2" port thread (PT, G, or NPT), and SC-series mounting hardware. Because this is an -S model, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the new cylinder. If you need integrated flow control, explore the SAUF valve-integrated option. For the 320 mm stroke, add external guides to prevent rod bending and side-load wear. Finally, a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU100X320S
- ✓ 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 SU100X320S FAQ
Yes, the SU100X320S is end-of-life. The direct replacement is the AirTAC SAU100X320S. It matches the 100 mm bore, 320 mm stroke, 1/2" port, 3927 N push force at 0.5 MPa, and SC-series mounting dimensions perfectly, so no mechanical redesign is required.
The bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. Because this is an -S magnet model, the original CS1-B/DS1-B switches are obsolete; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
