This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X225, 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 SU80X225
The AirTAC Airtac SU63-100 Standard Cylinder SU80X225 is a double-acting profile-type standard cylinder with a Ø80mm bore and 225mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X225, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X225
The AirTAC SU80X225 is a discontinued double-acting profile-type cylinder featuring an 80mm bore and 225mm stroke. It delivers 2513N push force at 0.5MPa and uses a 3/8 inch port. AirTAC replaced this legacy unit with the SAU80X225, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting. You simply order the SAU equivalent.
This compact extruded-aluminum body is shorter than an ISO 15552 cylinder of the same bore. Because this SKU lacks a magnet, it cannot accept sensors, whereas the SAU replacement uses modern CMSG/DMSG/EMSG switches. The SAU family also introduces a SAUF built-in-valve option the SU never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X225 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X225 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Replacing the Airtac SU63-100 Standard Cylinder SU80X225 with the SAU80X225
To replace the SU80X225, order the SAU80X225 direct: verify the 80mm bore, 225mm stroke, 3/8 inch port, M20x1.5 rod thread, and SC-series mounting. This non-magnet SKU cannot take a sensor; if you need position detection, the SAU upgrade requires CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For sizing both ways, a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore yields 3927N. A plain cylinder drifts on air loss since the cushion only decelerates, so use an external rod lock for held loads. The SAUF variant adds a built-in 4M valve if you need self-switching. At 225mm stroke, side-load rod-bending is low, but ensure guide alignment.
Replacement checklist
- ✓ Same bore / stroke → SAU80X225
- ✓ 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 SU80X225 FAQ
Yes, the SU80X225 is discontinued. The direct replacement is the SAU80X225. It matches the 80mm bore, 225mm stroke, 2513N force, 3/8 inch port, and SC-series mounting. You simply order the SAU80X225.
It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf max at 1.0MPa. This specific SKU has no magnet and cannot take a sensor. If sensing is needed, the SAU replacement uses CMSG/DMSG/EMSG switches.
