This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X495S, 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 SU80X495S
The AirTAC SU63-100 Standard Cylinder SU80X495S is a double-acting profile-type standard cylinder with a Ø80mm bore and 495mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X495S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X495S
The AirTAC SU80X495S is a discontinued double-acting profile cylinder with an 80mm bore and 495mm stroke. Delivering 2513 N push force at 0.5 MPa via a 3/8" port, it is replaced by the direct replacement SAU80X495S. This upgrade retains the exact bore, stroke, force, port, and SC-series mounting. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore.
The -S magnet on this legacy SU worked with CS1-B/DS1-B switches; the SAU replacement uses current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF built-in 4M solenoid valve option the SU lacked. Note that air cushions only decelerate; use an external rod lock to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X495S 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 SAU80X495S 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 SU80X495S Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line using 2513 N of thrust at 0.5 MPa, with the 495mm stroke clearing wide product lanes.
Vertical Lift Gate
Raises a 100 kg loading dock gate through 495mm; the 80mm bore handles the dead weight safely while external guides absorb lateral wind load.
Press Ejection
Ejects formed metal parts from a 80-ton press bed, using the compact profile body to fit tight machinery cells where space is restricted.
Replacing the Airtac SU63-100 Standard Cylinder SU80X495S with the SAU80X495S
To replace the SU80X495S, order the SAU80X495S, confirming the 80mm bore, 495mm stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this -S model has a magnet, you must switch from legacy CS1-B/DS1-B switches to the SAU's CMSG/DMSG/EMSG sensors. Size both ways: dropping to a 63mm bore yields 1559 N push at 0.5 MPa, while an 80mm bore gives 2513 N. For the 495mm stroke, use external guides to prevent rod bending under side loads. A plain cylinder drifts on air loss, so add a pilot-operated check valve or rod lock for load holding. If you need integrated control, explore the SAUF valve variant.
Replacement checklist
- ✓ Same bore / stroke → SAU80X495S
- ✓ 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 SU80X495S FAQ
Yes, the SU80X495S is discontinued. The direct replacement is the AirTAC SAU80X495S. It matches the 80mm bore, 495mm stroke, 2513 N force, 3/8" port, and SC-series mounting. You simply order the SAU80X495S.
The 80mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf maximum at 1.0 MPa. Because your SU has a -S magnet, note the SAU replacement switches from legacy CS1-B/DS1-B sensors to the current CMSG/DMSG/EMSG family.
