This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X255S, 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 SU100X255S
The AirTAC SU63-100 Standard Cylinder SU100X255S is a double-acting profile-type standard cylinder with a Ø100mm bore and 255mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X255S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X255S
The AirTAC SU100X255S is a discontinued double-acting profile-type cylinder with a 100mm bore and 255mm stroke. It delivers 3927 N push force at 0.5 MPa and uses a 1/2" port. AirTAC replaced this legacy unit with the SAU100X255S, a direct upgrade retaining the exact same body dimensions, output force, and SC-series mounting.
Because this is an -S magnet model, it originally used CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve, an option the SU line 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 SAU100X255S 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 SU100X255S 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.
Bulk Material Diversion
Actuates large heavy-duty diverters on high-throughput conveyor belts, using the 255mm stroke to re-route bulky items into secondary processing lanes.
Replacing the Airtac SU63-100 Standard Cylinder SU100X255S with the SAU100X255S
To replace this SU100X255S, order the SAU100X255S. Confirm the 1/2" port, M20x1.5 rod thread, and your SC-series mounting (LB/FA/FB/CA/CB). Since this SKU includes the -S magnet, note the sensor family changes from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG on the new SAU. If your application needs integrated controls, explore the SAUF variant for its built-in valve. For loads requiring holding on air loss, add an external rod lock or pilot-operated check valve, as standard cushions only decelerate. At 255mm stroke, rod bending is low risk, but always guide the load to prevent side-loading. If you need less force, step down to an 80mm bore (2513 N push @0.5 MPa); for more power, this 100mm bore is the largest standard profile option (3927 N push @0.5 MPa).
Replacement checklist
- ✓ Same bore / stroke → SAU100X255S
- ✓ 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 SU100X255S FAQ
Yes, the AirTAC SU100X255S is discontinued and end-of-life. The direct replacement is the SAU100X255S. It shares the same 100mm bore, 255mm stroke, 1/2" port, output force, and SC-series mounting, so it fits the same application directly.
The bore is 100mm with a 25mm rod. Force ratings are: push 3927 N and pull 3681 N at 0.5 MPa, push 5497 N at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. Because this is an -S model, it has a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
