This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X75STC, 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 SU80X75STC
The AirTAC Airtac SU63-100 Standard Cylinder SU80X75STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 75mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X75STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X75STC
The AirTAC SU80X75STC is a discontinued double-acting profile-type cylinder featuring an extruded aluminum barrel and adjustable air cushions at both ends. It delivers a robust push force of 2513 N and pull of 2268 N at 0.5 MPa, operating at speeds of 30-800 mm/s via its fixed 3/8" port.
AirTAC replaced this legacy unit with the SAU80X75STC, a direct upgrade retaining the exact 80mm bore, 75mm stroke, output force, and SC-series TC mounting interface. The SAU body is more compact than an ISO 15552 cylinder of the same size. Note that the SAU upgrade introduces the CMSG/DMSG/EMSG sensor family (replacing the old CS1-B/DS1-B switches) and offers a new SAUF built-in valve variant the SU line lacked.

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 SAU80X75STC 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 SU80X75STC Is Used
Package Diverting
Actuates TC-mounted routing gates on high-speed packaging lines, using the 2513 N push force to reliably redirect heavy cartons without bounce.
Pallet Stopping
Deploys a robust physical stop block at the end of gravity roller conveyors, securely halting 128 kg vertical-equivalent pallet loads.
Press Ejection
Ejects formed metal or composite parts from press beds, leveraging the 75mm stroke and adjustable 28mm cushions to prevent impact damage.
Replacing the Airtac SU63-100 Standard Cylinder SU80X75STC with the SAU80X75STC
To replace this discontinued SU80X75STC, order the SAU80X75STC. Verify your 3/8" port threads (PT, G, or NPT), the M20x1.5 rod-end connection, and your TC mounting hardware, which is fully reusable. Because this SKU includes a magnet (-S), you must upgrade your legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. If your application needs self-switching without external plumbing, consider the SAUF variant with its built-in 4M solenoid valve. For load holding, remember a standard cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for suspended loads. If sizing alternatives, the neighboring 63mm bore yields 1559 N push at 0.5 MPa, while the 100mm bore provides 3927 N at the same pressure.
Replacement checklist
- ✓ Same bore / stroke → SAU80X75STC
- ✓ 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 SU80X75STC FAQ
Yes, the AirTAC SU80X75STC is discontinued and end-of-life. The direct replacement is the SAU80X75STC. It shares the identical 80mm bore, 75mm stroke, 3/8" port, output force, and TC mounting interface, so it drops right into the same application.
At 0.5 MPa it provides 2513 N push and 2268 N pull; at 0.7 MPa it pushes 3518 N, and the theoretical maximum is 513 kgf at 1.0 MPa. Because this SKU has a magnet (-S), it originally used CS1-B/DS1-B switches; the SAU replacement requires the newer CMSG/DMSG/EMSG sensors.
