This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X225SCA, 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 SU80X225SCA
The AirTAC SU63-100 Standard Cylinder SU80X225SCA 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 SAU80X225SCA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X225SCA
The AirTAC SU80X225SCA is a discontinued double-acting profile-type cylinder featuring an 80 mm bore, a 225 mm non-standard stroke, and a CA mounting interface. It delivers 2513 N of push force at 0.5 MPa. AirTAC replaced this end-of-line unit with the SAU80X225SCA, a direct replacement retaining the exact bore, stroke, output force, 3/8" port, and SC-series mounting compatibility.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to supersede the legacy CS1-B/DS1-B switches used on this -S magnet model, and it offers a new SAUF built-in-valve variant. Note that a plain cylinder drifts on air loss; the cushions only decelerate, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X225SCA 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 SAU80X225SCA 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 SU80X225SCA Is Used
Mid-Stroke Pressing
Applies the 2513 N push force at 0.5 MPa over a 225 mm non-standard travel for custom stamping or alignment tasks.
Pallet Diversion
Uses the CA foot mount to push heavy pallets laterally, benefiting from the compact profile body to save space.
Replacing the Airtac SU63-100 Standard Cylinder SU80X225SCA with the SAU80X225SCA
To replace this SU80X225SCA, order the SAU80X225SCA, verifying the 80 mm bore, 225 mm stroke, 3/8" port, M20x1.5 rod thread, and CA mounting. Because this is a non-standard 225 mm stroke, expect a custom or extended lead time. If downsizing, a 63 mm bore yields 1559 N push at 0.5 MPa; if upsizing, a 100 mm bore provides 3927 N. At 225 mm, side-load rod-bending is moderate, but ensure guide alignment. The -S magnet means your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG on the SAU. For load holding on air loss, add a pilot-operated check valve or external rod lock, as cushions only decelerate. Consider the SAUF variant if you need a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X225SCA
- ✓ 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 SU80X225SCA FAQ
Yes, the SU80X225SCA is discontinued. The direct replacement is the SAU80X225SCA, which matches the 80 mm bore, 225 mm stroke, 2513 N force, 3/8" port, and CA mounting. You just order the SAU model.
It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and a max of 513 kgf at 1.0 MPa. Because this has an -S magnet, the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
