This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X225, 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 SU100X225
The AirTAC SU63-100 Standard Cylinder SU100X225 is a double-acting profile-type standard cylinder with a Ø100mm bore and 225mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X225, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X225
The AirTAC SU100X225 is a discontinued double-acting profile-type cylinder with a 100 mm bore and 225 mm stroke. As an end-of-line product, it is replaced directly by the SAU100X225. This direct upgrade maintains the exact extruded aluminium body, 1/2" port, M20x1.5 rod thread, and SC-series mounting, delivering 3927 N of push force at 0.5 MPa. Because 225 mm is a non-standard stroke length, the SAU replacement is built to this exact dimension.
Two notable upgrades exist in the SAU line: it uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches, and it offers a SAUF variant with a built-in 4M solenoid valve that the SU series lacked. This specific SU100X225 SKU has no magnet, so it cannot accept any magnetic switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X225 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 SAU100X225 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU100X225
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×225 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU100X225 Is Used
Heavy Stamping Press
Drives heavy-duty stamping and forming dies requiring substantial push force, using the 29 mm adjustable cushions to absorb high kinetic energy at stroke ends.
Pallet Lift Station
Lifts loaded pallets vertically, safely handling weights up to 200 kg when paired with external pilot-operated check valves to prevent drifting on air loss.
Bulk Material Divert
Actuates large-scale diverters or heavy gates on high-capacity conveyors, relying on the robust 25 mm piston rod to withstand lateral stress.
Replacing the Airtac SU63-100 Standard Cylinder SU100X225 with the SAU100X225
To replace the discontinued SU100X225, order the SAU100X225, confirming the 100 mm bore, 225 mm non-standard stroke, 1/2" port, and PT/G/NPT thread choice. Reuse your existing AirTAC SC-series mounting accessories, as the body footprint is identical. If downsizing is possible, an 80 mm bore provides 2513 N push at 0.5 MPa; if upsizing, note that 100 mm is the largest available profile bore. This non-magnetic version cannot support sensors, but if you previously used -S models, the SAU requires CMSG/DMSG/EMSG switches. For any stroke over 300 mm, guide the load to prevent rod bending and side-load wear. The air cushion only decelerates the piston; it does not hold the load on air loss, so add an external rod lock or pilot-operated check valve for vertical lifting.
Replacement checklist
- ✓ Same bore / stroke → SAU100X225
- ✓ 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 SU100X225 FAQ
Yes, the AirTAC SU100X225 is discontinued and end-of-life. The direct replacement is the SAU100X225. It features the same 100 mm bore, 225 mm stroke, 1/2" port, 801 kgf max force, and SC-series mounting compatibility, fitting directly into your existing setup.
At 0.5 MPa it provides 3927 N push and 3681 N pull; at 0.7 MPa it pushes 5497 N, and the theoretical max is 801 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot take a sensor. If you need sensing, the SAU replacement supports CMSG/DMSG/EMSG switches, replacing the older CS1-B/DS1-B format.
