This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X125S, 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 SU80X125S
The AirTAC SU63-100 Standard Cylinder SU80X125S is a double-acting profile-type standard cylinder with a Ø80mm bore and 125mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X125S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X125S
The AirTAC SU80X125S is a discontinued double-acting profile-type cylinder with an 80mm bore and 125mm stroke. Built with an extruded aluminium barrel, it is more compact than an ISO 15552 unit of the same bore and delivers a push force of 2513 N at 0.5 MPa. AirTAC replaced this legacy unit with the SAU80X125S, a direct upgrade retaining the exact 3/8" port, M20x1.5 rod thread, output force, and SC-series mounting footprint.
The SAU replacement introduces modern CMSG/DMSG/EMSG sensors, superseding the original CS1-B/DS1-B switches used on this -S magnet model. It also adds the SAUF variant with a built-in 4M solenoid valve, a feature the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X125S 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 SAU80X125S 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 SU80X125S Is Used
Pallet Diversion
Handles heavy pallet routing on packaging lines using the 2513 N push force at 0.5 MPa to reliably divert loads without mechanical lag.
Vertical Lift Gate
Raises material handling gates with a safe vertical lift capacity of roughly 128 kg, utilising the 125mm stroke for compact actuation.
Press Ejection
Ejects dense formed parts from stamping presses, taking advantage of the 28mm adjustable air cushions to brake the load smoothly at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU80X125S with the SAU80X125S
To replace the SU80X125S, order the SAU80X125S 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 SKU includes the -S magnet, you must upgrade your legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family. If your application requires integrated flow control, the new SAUF variant offers a built-in 4M solenoid valve. For sizing alternatives, dropping to a 63mm bore yields 1559 N push at 0.5 MPa, while an 80mm bore at 0.7 MPa provides 3518 N. Remember that a standard cylinder drifts without live air—the cushion only decelerates near stroke end—so install an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU80X125S
- ✓ 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 SU80X125S FAQ
Yes, the SU80X125S is discontinued. The direct replacement is the AirTAC SAU80X125S. It matches the original 80mm bore, 125mm stroke, 3/8" port, output force, and SC-series mounting accessories, so it fits the same application directly.
The 80mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical max of 513 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the new SAU unit.
