This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X720S, 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 SU100X720S
The AirTAC Airtac SU63-100 Standard Cylinder SU100X720S is a double-acting profile-type standard cylinder with a Ø100mm bore and 720mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X720S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X720S
The AirTAC SU100X720S is a discontinued double-acting profile-type cylinder with a 100mm bore and 720mm stroke. It delivers a push force of 3927 N and pull of 3681 N at 0.5 MPa, utilizing a 1/2" port and M20x1.5 rod thread. AirTAC replaced this legacy unit with the SAU100X720S, a direct upgrade retaining the exact bore, stroke, force, port, and SC-series mounting footprint.
Because this SKU includes a magnet (-S), it originally used CS1-B/DS1-B switches; the SAU replacement transitions to modern CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve, an option the SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X720S 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 SAU100X720S 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 SU100X720S Is Used
Heavy Stamping Press
Drives heavy tooling dies with 3927 N push at 0.5 MPa, relying on the 29mm adjustable cushions to absorb end-of-stroke impact.
Large Gate Diversion
Actuates heavy industrial routing gates over a 720mm span, requiring external guides to prevent rod bending during extension.
Replacing the Airtac SU63-100 Standard Cylinder SU100X720S with the SAU100X720S
To replace the SU100X720S, order the SAU100X720S, verifying your 1/2" port, M20x1.5 thread, and SC-series mounting (LB/FA/FB/CA/CB) stay identical. If downsizing, an 80mm bore yields 2513 N push at 0.5 MPa; if upsizing is impossible, this 100mm bore maxes at 801 kgf at 1.0 MPa. The -S magnet means you must switch from legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches. For the 720mm stroke, use an external guide to prevent rod bending and side-load wear. Note that a plain cylinder drifts without live air—the cushions only decelerate—so add an external rod lock or pilot-operated check valve for load holding. If self-switching is needed, explore the new SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU100X720S
- ✓ 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 SU100X720S FAQ
Yes, the SU100X720S is discontinued. The direct replacement is the AirTAC SAU100X720S. It shares the same 100mm bore, 720mm stroke, output force, 1/2" port, and SC-series mounting accessories, so it fits the same application directly.
It delivers 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 legacy CS1-B/DS1-B switches are retired; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
