This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X120, 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 SU100X120
The AirTAC SU63-100 Standard Cylinder SU100X120 is a double-acting profile-type standard cylinder with a Ø100mm bore and 120mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X120, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X120
The AirTAC SU100X120 is a discontinued double-acting profile-type cylinder with a 100mm bore and 120mm stroke. Delivering 3927 N push force at 0.5 MPa, its direct replacement is the SAU100X120, matching the 1/2" port, M20x1.5 rod thread, and SC-series mounting.
This extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore. Because this SKU lacks a magnet, it cannot take a sensor; the SAU upgrade also switches to CMSG/DMSG/EMSG switches and adds a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X120 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 SAU100X120 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 SU100X120 Is Used
Heavy Stamping Press
Drives heavy-duty stamping and forming dies requiring substantial thrust, utilizing the 3927 N push force at 0.5 MPa to shape thick metal components reliably.
Large Mold Clamping
Secures large injection molds or heavy industrial fixtures during processing, relying on the 100mm bore's robust 7068 N output at 0.9 MPa for rigid holding.
Replacing the Airtac SU63-100 Standard Cylinder SU100X120 with the SAU100X120
To replace the discontinued SU100X120, order the SAU100X120 direct equivalent, verifying the 1/2" port, M20x1.5 thread, and SC-series mounts. Since this specific SKU has no magnet (-S), it cannot accept a sensor; if sensing is needed, the SAU replacement requires CMSG/DMSG/EMSG switches. For sizing both ways, the 80mm bore offers 2513 N push at 0.5 MPa, while the 100mm bore provides 5497 N at 0.7 MPa. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock for held loads. The SAUF variant adds a built-in valve the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU100X120
- ✓ 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 SU100X120 FAQ
Yes, the AirTAC SU100X120 is discontinued. The direct replacement is the SAU100X120, which shares the same 100mm bore, 120mm stroke, 1/2" port, output force, and SC-series mounting accessories.
At 0.5 MPa it pushes 3927 N and pulls 3681 N; at 0.7 MPa it pushes 5497 N, with a theoretical max of 801 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
