This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X550STC, 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 SU100X550STC
The AirTAC SU63-100 Standard Cylinder SU100X550STC is a double-acting profile-type standard cylinder with a Ø100mm bore and 550mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X550STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X550STC
The AirTAC SU100X550STC is a discontinued double-acting profile-type cylinder with a 100mm bore and 550mm stroke. Delivering 3927 N push force at 0.5 MPa, it uses an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this unit with the SAU100X550STC, a direct replacement retaining the exact 1/2 inch port, M20x1.5 rod thread, TC mounting interface, and 801 kgf maximum force.
Upgrading to the SAU keeps your SC-series mounting hardware but changes the sensor family: the legacy CS1-B/DS1-B switches on this -S magnet model are replaced by modern CMSG/DMSG/EMSG switches. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered.

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 SAU100X550STC 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 SU100X550STC Is Used
Heavy Press Stamping
Drives large metal forming dies requiring high thrust, using the 3927 N push force at 0.5 MPa to deform heavy gauge materials.
Bulk Material Diversion
Actuates heavy routing gates on high-capacity lines, utilizing the TC mount and compact profile to fit tight transfer zones.
Replacing the Airtac SU63-100 Standard Cylinder SU100X550STC with the SAU100X550STC
To replace the SU100X550STC, order the SAU100X550STC and verify your 1/2 inch port threads (PT, G, or NPT) alongside the TC mounting bracket. Because this -S model has a piston magnet, note that your legacy CS1-B/DS1-B switches must be swapped to CMSG/DMSG/EMSG sensors on the new SAU cylinder. If you need self-switching capability, consider the SAUF100 variant which integrates a 4M solenoid valve directly into the body. With a 550mm stroke, you must use external guides to prevent rod bending and side-load damage. For neighboring bores, an 80mm bore provides 2513 N push at 0.5 MPa, while this 100mm bore yields 5497 N at 0.7 MPa. Remember that a plain cylinder drifts on air loss; the adjustable 29mm cushions only decelerate near stroke end, so install an external rod lock or pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU100X550STC
- ✓ 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 SU100X550STC FAQ
Yes, the AirTAC SU100X550STC is discontinued. The direct replacement is the SAU100X550STC. It shares the identical 100mm bore, 550mm stroke, 1/2 inch port, TC mounting, and output force, so it fits the same application without mechanical modifications.
The bore provides 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 obsolete; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
