This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X750S, 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 SU80X750S
The AirTAC SU63-100 Standard Cylinder SU80X750S is a double-acting profile-type standard cylinder with a Ø80mm bore and 750mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X750S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X750S
The AirTAC SU80X750S is a discontinued double-acting profile-type cylinder with an 80mm bore and 750mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, peaking at 513kgf. AirTAC replaced this unit with the SAU80X750S, a direct upgrade sharing the exact bore, stroke, force, 3/8 port and SC-series mounting. The extruded aluminium body is more compact than an ISO 15552 cylinder of the same size.
Because your SKU includes the -S magnet, note the SAU upgrade switches from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF built-in-valve variant the SU lacked. A plain cylinder drifts without live air; the cushions only decelerate.

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 SAU80X750S 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 SU80X750S Is Used
Pallet Diversion
Uses the 2513N push at 0.5MPa to deflect heavy pallets along a high-throughput conveyor line, with the 750mm stroke reaching across the track.
Material Ejection
Pushes completed assemblies out of a machining cell, taking advantage of the adjustable 28mm cushions to stop heavy loads smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X750S with the SAU80X750S
To replace this discontinued SU80X750S, order the SAU80X750S. Confirm the 3/8 port, M20x1.5 rod thread and PT/G/NPT thread choice. Since your SKU has the -S magnet, plan to upgrade to CMSG/DMSG/EMSG sensors. If you need load holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. For the 750mm stroke, use an external guide to prevent rod bending and side-load wear. If force is tight, a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore offers 3927N. The SAUF valve-integrated option is available if you want self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU80X750S
- ✓ 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 SU80X750S FAQ
Yes, the AirTAC SU80X750S is discontinued. The direct replacement is the SAU80X750S. It shares the same 80mm bore, 750mm stroke, 513kgf max force, 3/8 port and SC-series mounting, so it fits the same application without mechanical changes.
At 0.5MPa it provides 2513N push and 2268N pull, increasing to 3518N at 0.7MPa and 4523N at 0.9MPa. The theoretical max is 513kgf at 1.0MPa. Because this is an -S magnet model, it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
