This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X115S, 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 SU80X115S
The AirTAC SU63-100 Standard Cylinder SU80X115S is a double-acting profile-type standard cylinder with a Ø80mm bore and 115mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X115S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X115S
The AirTAC SU80X115S is a discontinued double-acting profile cylinder with an 80 mm bore and 115 mm stroke. Delivering 2513 N of push force at 0.5 MPa, it uses an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same size. AirTAC replaced this unit with the SAU80X115S, a direct replacement retaining the exact 3/8" port, M20x1.5 rod thread, output force, and SC-series mounting accessories.
When upgrading to the SAU80X115S, the body dimensions and 28 mm adjustable cushions remain identical, but the sensor family changes. Your legacy CS1-B/DS1-B switches are replaced by current CMSG/DMSG/EMSG sensors. The new 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 SAU80X115S 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 SAU80X115S 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 SU80X115S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×115 | 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 SU80X115S Is Used
Package Diverting
Handles heavy carton routing on packaging lines, utilizing the 115 mm stroke to push substantial boxes cleanly between conveyor belts.
Pallet Stopping
Acts as a robust end-stop for loaded pallets, using the 2513 N push force at 0.5 MPa to halt movement without mechanical flex.
Press Ejection
Ejects dense formed parts from press beds, where the compact profile body and 28 mm cushions absorb the sudden end-of-stroke impact.
Replacing the Airtac SU63-100 Standard Cylinder SU80X115S with the SAU80X115S
To replace your SU80X115S, order the SAU80X115S direct equivalent, confirming the 80 mm bore, 115 mm stroke, 3/8" port, and default PT threads. Because this SKU includes a magnet (-S), note that your existing CS1-B/DS1-B switches will not fit the SAU groove; you must upgrade to CMSG/DMSG/EMSG sensors. If your application requires integrated flow control, explore the SAUF valve-integrated variant. For loads needing 3518 N of push force at 0.7 MPa, this 80 mm bore is correct, but if you need less force, stepping down to a 63 mm bore (1559 N push at 0.5 MPa) saves space. Remember that a standard cylinder drifts without live air—the cushions only decelerate—so install an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU80X115S
- ✓ 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 SU80X115S FAQ
Yes, the AirTAC SU80X115S is discontinued and end-of-life. The direct replacement is the SAU80X115S. It provides identical performance with the same 80 mm bore, 115 mm stroke, 3/8" port, and SC-series mounting accessories, so it fits the same application directly.
The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a maximum theoretical force of 513 kgf at 1.0 MPa. Because this is an -S magnet model, note that the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
