This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X25, 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 SU100X25
The AirTAC Airtac SU63-100 Standard Cylinder SU100X25 is a double-acting profile-type standard cylinder with a Ø100mm bore and 25mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X25, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X25
The AirTAC SU100X25 is a discontinued double-acting profile-type cylinder with a 100mm bore and 25mm stroke. Delivering 3927N push force at 0.5MPa, it uses an extruded aluminium barrel that is shorter than an ISO 15552 cylinder of the same bore. The direct replacement is the SAU100X25, matching the body, 1/2in port, M20x1.5 rod thread and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor; the -S version of the SAU replacement uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. The SAU line also adds a SAUF built-in-valve option the SU never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X25 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 SAU100X25 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 SU100X25 Is Used
Heavy Stamp Pressing
Applies the 3927N push at 0.5MPa for short 25mm stamping, forming and riveting operations in automated metal fabrication lines.
Pallet Jambs & Stops
Acts as a robust physical stop or heavy-duty diverter arm in conveyor systems, leveraging the 25mm stroke to halt loaded pallets.
Clamp Actuation
Provides high-force clamping of large workpieces or moulds inside machining centres, where the compact profile body saves valuable space.
Replacing the Airtac SU63-100 Standard Cylinder SU100X25 with the SAU100X25
To replace this SU100X25, order the SAU100X25 keeping the 100mm bore, 25mm stroke, 1/2in port and SC-series mounts. This no-magnet SKU cannot take a switch; if sensing is needed, order the SAU100X25-S and migrate to CMSG/DMSG/EMSG sensors. Sizing both ways: a neighbouring 80mm bore yields 2513N push at 0.5MPa, while this 100mm bore hits 5497N at 0.7MPa. For load holding on air loss, fit an external rod lock or pilot-operated check valve, as the cushion only decelerates. The SAUF valve-integrated variant can simplify cycle control.
Replacement checklist
- ✓ Same bore / stroke → SAU100X25
- ✓ 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 SU100X25 FAQ
Yes, the SU100X25 is discontinued. The direct replacement is the AirTAC SAU100X25. It matches the 100mm bore, 25mm stroke, output force, 1/2in port and SC-series mounting accessories, fitting the exact same application envelope.
The 100mm bore provides 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, and a theoretical max of 801kgf at 1.0MPa. This specific no-magnet SKU cannot accept a sensor; the -S version of the SAU replacement uses CMSG/DMSG/EMSG switches, replacing the legacy CS1-B/DS1-B.
