This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X250STC, 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 SU80X250STC
The AirTAC SU63-100 Standard Cylinder SU80X250STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 250mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X250STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X250STC
The AirTAC SU80X250STC is a discontinued double-acting profile cylinder with an 80mm bore and 250mm stroke, delivering 2513N push and 2268N pull at 0.5MPa. Its extruded aluminium barrel makes it shorter than an ISO 15552 cylinder of the same bore, and it uses an M20x1.5 rod with a 3/8" port. AirTAC replaced this EOL unit with the SAU80X250STC, a direct sharing the exact bore, stroke, force, port and SC-series TC mounting.
Because the -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches, upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

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 SAU80X250STC 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 SU80X250STC Is Used
Pallet Diversion
Pushes heavy pallets laterally across transfer lines using 2513N thrust at 0.5MPa, guided to prevent side-load wear on the 250mm stroke.
Press Ejection
Ejects dense formed parts from machinery, utilising the compact profile body and TC mount to fit tight press enclosures.
Replacing the Airtac SU63-100 Standard Cylinder SU80X250STC with the SAU80X250STC
To replace the SU80X250STC, order the SAU80X250STC and verify your 80mm bore, 250mm stroke, 3/8" port (PT/G/NPT) and TC mounting accessory are matched. If downsizing, a 63mm bore yields 1559N push at 0.5MPa; if upsizing, a 100mm bore gives 3927N. The -S magnet means you must swap legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors on the SAU. A plain cylinder drifts on air loss—the 28mm cushion only decelerates—so fit an external rod lock or pilot-operated check valve for held loads. At 250mm stroke, guide the load to prevent rod bending and side-load wear. For self-switching, explore the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU80X250STC
- ✓ 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 SU80X250STC FAQ
Yes, the SU80X250STC is discontinued. The direct replacement is the SAU80X250STC, which shares the same 80mm bore, 250mm stroke, 3/8" port, force and TC mounting.
It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a max of 513kgf at 1.0MPa. The -S magnet used legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
