This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X385S, 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 SU80X385S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X385S is a double-acting profile-type standard cylinder with a Ø80mm bore and 385mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X385S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X385S
The AirTAC SU80X385S is a discontinued double-acting profile-type cylinder with an 80mm bore and 385mm stroke. Built with an extruded aluminium barrel, it is shorter and more compact than an ISO 15552 unit of the same size, and it delivers 2513 N of push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAU80X385S, a direct upgrade retaining the exact 80mm bore, 385mm stroke, output force, 3/8" port, and SC-series mounting.
When migrating to the SAU80X385S, your body dimensions and 25 mm piston rod remain identical, but the sensor family changes: this SU -S model used legacy CS1-B/DS1-B switches, whereas the SAU requires current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X385S 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 SAU80X385S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×385 | 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 SU80X385S Is Used
Pallet Diversion
Pushes heavy pallets sideways off a high-speed line using the 2513 N thrust at 0.5 MPa, absorbing end-stop impact via the 28mm adjustable cushions.
Vertical Lift Gate
Raises a 128 kg material gate through 385mm of travel, benefiting from the compact profile body to fit tight structural clearances.
Press Ejection
Ejects dense formed parts from a press bed, relying on the 25mm rod and external guides to handle the long 385mm extension without bending.
Replacing the Airtac SU63-100 Standard Cylinder SU80X385S with the SAU80X385S
To replace the SU80X385S, order the SAU80X385S and verify your 3/8" port threads (PT, G, or NPT) alongside your SC-series mounting hardware (LB, FA, FB, CA, CB, or TC). Because this is an -S magnet model, you must replace the old CS1-B/DS1-B reed switches with CMSG/DMSG/EMSG sensors. If you need integrated flow control, explore the SAUF valve-integrated variant. Sizing context: if you need less force, a 63mm bore provides 1559 N push at 0.5 MPa; if you need more, a 100mm bore yields 3927 N. Remember that a standard cylinder drifts without live air—the 28mm adjustable cushions only decelerate the piston near stroke end, so add an external rod lock or pilot-operated check valve for held loads. Finally, at 385mm of travel, prevent rod bending by guiding the load externally to avoid side-loading.
Replacement checklist
- ✓ Same bore / stroke → SAU80X385S
- ✓ 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 SU80X385S FAQ
Yes, the SU80X385S is discontinued. The direct replacement is the AirTAC SAU80X385S. It matches the 80mm bore, 385mm stroke, 3/8" port, and SC-series mounting, so it drops right into the same application.
The SAU80X385S outputs 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf maximum at 1.0 MPa. Because your SU model has a magnet (-S), note that the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU.
