This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X1230S, 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 SU100X1230S
The AirTAC SU63-100 Standard Cylinder SU100X1230S is a double-acting profile-type standard cylinder with a Ø100mm bore and 1230mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X1230S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X1230S
The AirTAC SU100X1230S is a discontinued double-acting profile-type cylinder with a 100 mm bore and 1230 mm stroke. Delivering 3927 N push force at 0.5 MPa, it features a 1/2 inch air port and a 25 mm piston rod. AirTAC replaced this EOL unit with the SAU100X1230S, a direct replacement retaining the exact same body dimensions, output force, port size, and SC-series mounting.
Because this is a non-standard 1230 mm stroke, you must use external guides to prevent rod bending under side loads. The SAU upgrade introduces current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches on this -S SKU, and adds a SAUF built-in valve option.

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 SAU100X1230S 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 SU100X1230S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or workpieces across extended conveyor gaps using its 3927 N push force at 0.5 MPa over a 1230 mm travel distance.
Large Assembly Pressing
Provides steady actuation to seat large housings or bearings, relying on adjustable air cushions to decelerate the heavy tooling at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU100X1230S with the SAU100X1230S
To replace the SU100X1230S, order the SAU100X1230S and confirm your 1/2 inch port thread (PT, G, or NPT) plus SC-series mounting hardware. Because the -S magnet is present, note that your old CS1-B/DS1-B switches will not fit the SAU sensor groove; you must upgrade to CMSG/DMSG/EMSG sensors. If you need true load holding on air loss, a plain cylinder drifts because the adjustable cushion only decelerates, so add an external rod lock or pilot-operated check valve. For this 1230 mm stroke, external guide rails are critical to prevent rod bending. If you need less force, step down to an 80 mm bore (2513 N push at 0.5 MPa); if you need more, note the 100 mm bore maxes at 801 kgf at 1.0 MPa. Consider the SAUF variant if you want a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU100X1230S
- ✓ 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 SU100X1230S FAQ
Yes, the SU100X1230S is discontinued. The direct replacement is the AirTAC SAU100X1230S. It matches the 100 mm bore, 1230 mm stroke, 1/2 inch port, and SC-series mounting. The body and force are unchanged, but you will need CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
The 1/2 inch port is fixed by the 100 mm bore. At 0.5 MPa it provides 3927 N push and 3681 N pull force. At 0.7 MPa push is 5497 N, and at 0.9 MPa it is 7068 N.
