This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X1200S, 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 SU100X1200S
The AirTAC SU63-100 Standard Cylinder SU100X1200S is a double-acting profile-type standard cylinder with a Ø100mm bore and 1200mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X1200S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X1200S
The AirTAC SU100X1200S is a discontinued double-acting profile-type cylinder with a 100mm bore and 1200mm stroke. It delivers 3927 N push and 3681 N pull at 0.5 MPa, utilizing a 1/2" port and a 25mm piston rod. AirTAC replaced this end-of-line unit with the SAU100X1200S direct replacement, matching the exact bore, stroke, output force, port size, and SC-series mounting accessories.
The SAU upgrade retains the compact extruded aluminum body but modernizes the sensor groove for current CMSG/DMSG/EMSG switches, whereas this legacy SU-S model used older CS1-B/DS1-B reed switches. The new SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series 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 SAU100X1200S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

|---|---|
| 100 | Bore size in mm. |
| ×1200 | 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 SU100X1200S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 3927 N of push force at 0.5 MPa, utilizing the 1200mm stroke for deep-draw operations.
Long-Stroke Material Transfer
Moves heavy structural components between machining stations, relying on external guides to support the 1200mm stroke and prevent rod bending.
Replacing the Airtac SU63-100 Standard Cylinder SU100X1200S with the SAU100X1200S
To replace this SU100X1200S, order the SAU100X1200S by confirming the 100mm bore, 1200mm stroke, 1/2" port, M20x1.5 rod thread, and SC-series mounting. Because this SKU includes the -S magnet, note that your legacy CS1-B/DS1-B switches must change to the SAU's CMSG/DMSG/EMSG sensor family. If you need self-switching, explore the SAUF valve-integrated option. Sizing both ways: stepping down to an 80mm bore yields 2513 N push at 0.5 MPa, while this 100mm bore provides 5497 N at 0.7 MPa. A plain cylinder drifts on air loss—the 29mm cushions only decelerate—so add an external rod lock or pilot-operated check valve for held loads. Finally, the 1200mm stroke demands external guide rails to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same bore / stroke → SAU100X1200S
- ✓ 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 SU100X1200S FAQ
Yes, the SU100X1200S is discontinued. The direct replacement is the AirTAC SAU100X1200S. It shares the identical 100mm bore, 1200mm stroke, 1/2" port, output force, and SC-series mounting, so it fits the same application directly.
This double-acting cylinder pushes 3927 N and pulls 3681 N at 0.5 MPa, pushes 5497 N at 0.7 MPa, and reaches 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 obsolete; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
