This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X80S, 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 SU100X80S
The AirTAC Airtac SU63-100 Standard Cylinder SU100X80S is a double-acting profile-type standard cylinder with a Ø100mm bore and 80mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X80S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X80S
The AirTAC SU100X80S is a discontinued double-acting profile-type cylinder featuring an integrated piston magnet for legacy CS1-B/DS1-B switches. Delivering 3927 N of push force at 0.5 MPa, its direct replacement is the SAU100X80S, which preserves the 100 mm bore, 80 mm stroke, 1/2" port, and SC-series mounting. This extruded aluminum body is shorter and more compact than an ISO 15552 cylinder of the same bore.
When upgrading to the SAU100X80S, the body, M20x1.5 rod thread, and 29 mm adjustable cushions remain identical, but the sensor family changes to the modern CMSG/DMSG/EMSG switches. The 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 SAU100X80S 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 SU100X80S Is Used
Heavy-Duty Pressing
Applies up to 3927 N at 0.5 MPa for seating bearings, stamping components, or forming light-gauge metal in automated machinery.
High-Force Clamping
Secures large workpieces or heavy molds during machining and welding operations where a compact 100 mm profile body is required.
Replacing the Airtac SU63-100 Standard Cylinder SU100X80S with the SAU100X80S
To replace this discontinued SU100X80S, order the SAU100X80S direct equivalent, verifying your 1/2" port threads (PT, G, or NPT) and SC-series mounting brackets (LB, FA, FB, CA, CB, or TC). Because this SKU includes a magnet (-S), note that your old CS1-B/DS1-B switches are obsolete and must be upgraded to CMSG/DMSG/EMSG sensors on the new cylinder. If you need higher force, the neighboring 80 mm bore yields 2513 N push at 0.5 MPa, while pushing the pressure to 0.7 MPa on this 100 mm bore gives 5497 N. A plain cylinder does not hold load without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for vertical holding. For applications needing self-switching, consider the SAUF valve-integrated variant. Although this 80 mm stroke is short, always ensure adequate guide support to prevent rod-bending side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU100X80S
- ✓ 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 SU100X80S FAQ
Yes, the AirTAC SU100X80S is discontinued. The direct replacement is the SAU100X80S. It offers identical 100 mm bore, 80 mm stroke, 1/2" port, output force, and SC-series mounting compatibility. You simply order the SAU equivalent.
The 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. Because this SU100X80S has a magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to current CMSG/DMSG/EMSG sensors.
