This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X800S, 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 SU80X800S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X800S is a double-acting profile-type standard cylinder with a Ø80mm bore and 800mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X800S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X800S
The AirTAC SU80X800S is a discontinued double-acting profile cylinder with an 80mm bore and 800mm stroke. Delivering 2513N push and 2268N pull at 0.5MPa, its direct replacement is the SAU80X800S. The SAU retains the same extruded aluminium body, 3/8 port, M20x1.5 rod thread and SC-series mounting, making it a true mechanical swap.
Two key upgrades exist: the SAU replaces this model's legacy CS1-B/DS1-B sensors with current CMSG/DMSG/EMSG switches, and the SAU line introduces a SAUF variant with a built-in valve the SU lacked. Note that a standard cylinder drifts without live air; the cushion only decelerates.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X800S 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 SAU80X800S 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 SU80X800S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets along an 800mm run using 2513N of thrust at 0.5MPa, requiring external guides to support the extended rod.
Heavy Assembly Press Stand
Provides 3518N of thrust at 0.7MPa to seat large industrial components, relying on adjustable cushions to stop the mass smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X800S with the SAU80X800S
To replace this SU80X800S, order the SAU80X800S, confirming the 80mm bore, 800mm stroke, 3/8 port and PT/G/NPT thread choice. Reuse your existing SC-series mounts. Because this SKU has the -S magnet, you must migrate from legacy CS1-B/DS1-B switches to the SAU's CMSG/DMSG/EMSG sensors. If you need higher force, the 100mm bore offers 3927N push at 0.5MPa; if less is required, the 63mm bore provides 1559N. At 800mm, the Ø25mm rod is vulnerable to bending under side loads, so use an external guide to prevent premature seal wear. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the cushion only decelerates. If valve integration is desired, explore the SAUF variant.
Replacement checklist
- ✓ Same bore / stroke → SAU80X800S
- ✓ 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 SU80X800S FAQ
Yes, the SU80X800S is discontinued. The direct replacement is the AirTAC SAU80X800S. It matches the 80mm bore, 800mm stroke, 2513N thrust, 3/8 port and SC-series mounting. You must upgrade the -S magnet sensors from legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG family.
The 3/8 port is fixed by the 80mm bore. At 0.5MPa it provides 2513N push and 2268N pull. At 0.7MPa push is 3518N, and at 0.9MPa it is 4523N. The theoretical maximum force is 513kgf at 1.0MPa. Operating speed is 30-800mm/s.
