This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X1100S, 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 SU80X1100S
The AirTAC SU63-100 Standard Cylinder SU80X1100S is a double-acting profile-type standard cylinder with a Ø80mm bore and 1100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X1100S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X1100S
The AirTAC SU80X1100S is a discontinued double-acting profile-type cylinder with an 80mm bore and 1100mm stroke. Built with an extruded aluminium barrel and adjustable air cushions at both ends, it delivers 2513 N push and 2268 N pull at 0.5 MPa. The direct replacement is the SAU80X1100S, matching the bore, stroke, 3/8" port, M20x1.5 rod thread and SC-series mounting.
Upgrading to the SAU keeps the compact profile shorter than an ISO 15552 cylinder of the same bore, but the -S magnet now requires current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve that the SU line lacked. Remember that a plain cylinder drifts on air loss; the cushions only decelerate near stroke end, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X1100S 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 SAU80X1100S 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 SU80X1100S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets along a 1100mm conveyor section using 2513 N of thrust at 0.5 MPa, requiring external guides to prevent rod bending over the long travel.
Large Assembly Press
Actuates a heavy forming tool over 1100mm, using the 28mm adjustable air cushions at both ends to decelerate the 80mm piston smoothly before end-of-stroke.
Replacing the Airtac SU63-100 Standard Cylinder SU80X1100S with the SAU80X1100S
To replace this discontinued SU80X1100S, order the SAU80X1100S direct equivalent, confirming the 80mm bore, 1100mm stroke, 3/8" port, M20x1.5 thread and SC-series mounting. If sizing both ways, the neighbouring 63mm bore provides 1559 N push while the 100mm bore offers 3927 N at 0.5 MPa. Because the 1100mm stroke is long, prevent rod bending by guiding the load externally to avoid side-load damage. The -S magnet means you must switch from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors on the SAU. For load holding on air loss, add a pilot-operated check valve or rod lock, and consider the SAUF variant if you need a built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X1100S
- ✓ 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 SU80X1100S FAQ
Yes, the SU80X1100S is discontinued. The direct replacement is the SAU80X1100S, which matches the 80mm bore, 1100mm stroke, 3/8" port, output force and SC-series mounting. You must upgrade your sensors, as the SAU uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
The 80mm bore features a 3/8" port and a 25mm piston rod. It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
