This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X1400S, 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 SU100X1400S
The AirTAC SU63-100 Standard Cylinder SU100X1400S is a double-acting profile-type standard cylinder with a Ø100mm bore and 1400mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X1400S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X1400S
The AirTAC SU100X1400S is a discontinued double-acting profile-type cylinder with a 100mm bore and 1400mm stroke. It delivers 3927 N push and 3681 N pull at 0.5 MPa, making it a heavy-duty actuator. AirTAC replaced this EOL unit with the SAU100X1400S direct replacement, matching the exact 1/2" port, M20x1.5 rod thread, 29mm cushions, output force and SC-series mounting.
Because this is a 1400mm long-stroke unit, external guide rails are recommended to prevent rod bending under side loads. The -S magnet on this legacy model worked with CS1-B/DS1-B switches, but the SAU replacement requires current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid 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 SAU100X1400S 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 SU100X1400S Is Used
Pallet Transfer Line
Drives heavy pallets over 1400mm cycles where the 3927N push force at 0.5MPa easily overcomes friction without requiring maximum pressure.
Automated Press Ejection
Ejects dense manufactured parts using the 801 kgf maximum theoretical force, relying on the 29mm adjustable cushions to decelerate.
Replacing the Airtac SU63-100 Standard Cylinder SU100X1400S with the SAU100X1400S
To replace the SU100X1400S, order the SAU100X1400S direct equivalent, verifying your 1/2" port, M20x1.5 rod thread, PT/G/NPT thread standard, and SC-series mounting hardware. If downsizing, the 80mm bore yields 2513 N push at 0.5 MPa; if upsizing is needed, note 100mm is the largest profile bore. The 1400mm stroke is within the 1500mm standard limit, but you must use external guides to prevent rod bending on this long cylinder. If your machine needs the -S magnet, remember the SAU uses CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. For intermediate stopping, add an external rod lock or pilot-operated check valve, as cushions only decelerate and cannot hold a load. The SAUF valve-integrated option can simplify plumbing if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU100X1400S
- ✓ 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 SU100X1400S FAQ
Yes, the SU100X1400S is discontinued. The direct replacement is the SAU100X1400S, which shares the same 100mm bore, 1400mm stroke, 1/2" port, force output and SC-series mounting. You must only update your sensors, as the SAU uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
At 0.5 MPa it provides 3927 N push and 3681 N pull; at 0.7 MPa it pushes 5497 N, and 7068 N at 0.9 MPa. The theoretical maximum is 801 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, speed is 30-800 mm/s, and the 29mm cushions only decelerate the load—they will not hold it without live air.
