This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X80, 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 SU100X80
The AirTAC Airtac SU63-100 Standard Cylinder SU100X80 is a double-acting profile-type standard cylinder with a Ø100mm bore and 80mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X80, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X80
The AirTAC SU100X80 is a discontinued double-acting profile-type standard cylinder with an 80 mm stroke and 100 mm bore. It delivers 3927 N push and 3681 N pull at 0.5 MPa, making it a heavy-duty choice. AirTAC replaced this end-of-line unit with the SAU100X80. This direct upgrade retains the exact 1/2 inch port, M20x1.5 rod thread, 29 mm cushions, and SC-series mounting, so it fits your existing setup perfectly.
Because this specific SKU lacks a magnet, it cannot accept a sensor. If you previously used switches, note the SAU family upgrades to CMSG/DMSG/EMSG sensors, and the new SAUF variant even integrates a built-in 4M solenoid valve the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X80 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X80 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 SU100X80 Is Used
Heavy Pressing
Drives heavy stamping and pressing tasks, utilizing 3927 N of push force at 0.5 MPa to seat large bearings or form thick materials.
Pallet Handling
Pushes loaded pallets or heavy totes along conveyor lines, where the 100 mm bore and 80 mm stroke provide the necessary thrust.
Mold Clamping
Secures large injection molds or heavy industrial fixtures, providing reliable holding power during manufacturing cycles.
Replacing the Airtac SU63-100 Standard Cylinder SU100X80 with the SAU100X80
To replace this cylinder, order the SAU100X80. Verify your thread type (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, TC, TCM1), as they are fully interchangeable. Since this specific SU100X80 has no magnet, it cannot hold a sensor; if your application requires position detection, you will need to move to an SAU100X80S and update your switches to the current CMSG/DMSG/EMSG family. Sizing both ways: if you need less force, stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa, while staying at 100 mm bore gives you up to 7068 N at 0.9 MPa. A plain cylinder cannot hold a load without live air—the cushions only decelerate—so add an external rod lock or pilot-operated check valve for vertical safety. For larger loads, the SAUF valve-integrated option is available on the replacement.
Replacement checklist
- ✓ Same bore / stroke → SAU100X80
- ✓ 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 SU100X80 FAQ
Yes, the SU100X80 is discontinued. The direct replacement is the SAU100X80. It shares the same 100 mm bore, 80 mm stroke, 1/2 inch port, output force, and SC-series mounting, allowing a direct physical swap.
It provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a maximum theoretical force of 801 kgf at 1.0 MPa. It cannot hold a load without live air; the cushions only decelerate, so use an external rod lock for vertical loads.
