This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X80FA, 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.

The AirTAC Airtac SU63-100 Standard Cylinder SU80X80FA is a double-acting profile-type standard cylinder with a Ø80mm bore and 80mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X80FA, which matches its bore, stroke, force and mounting.
The AirTAC SU80X80FA is a discontinued double-acting profile-type cylinder with an 80mm bore and 80mm stroke. Delivering 2513N push and 2268N pull at 0.5MPa, its direct replacement is the SAU80X80FA, retaining the same 3/8 port, M20x1.5 rod thread, and SC-series FA foot mount interface. This extruded aluminium body is more compact than an ISO 15552 cylinder of the same bore.
Because this SKU lacks a magnet, it cannot accept a sensor. If sensing is needed, the SAU replacement uses current CMSG/DMSG/EMSG switches (the SU used legacy CS1-B/DS1-B). The SAU family also adds a SAUF variant with a built-in valve, an option the SU line never had.

| Max (@1.0 MPa) | 513 kgf | |
The SAU80X80FA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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.
Applies 2513N of push force at 0.5MPa to seat bearings and pins into housings on an automated machining line.
Drives an FA foot-mounted diverter arm to route heavy cartons off a main conveyor belt at high cycling speeds.
Acts as a robust end-of-line stop gate for loaded pallets, absorbing kinetic energy using its adjustable 28mm air cushions.
To replace this discontinued SU80X80FA, order the SAU80X80FA with the exact 80mm bore, 80mm stroke, 3/8 port, and FA foot mount. Verify your thread standard (PT/G/NPT) during ordering. Since this specific SKU has no magnet (-S), it cannot support magnetic sensing; if your application requires position detection, the SAU upgrade utilizes CMSG/DMSG/EMSG switches. When sizing, the 80mm bore yields 2513N push at 0.5MPa; if you need less force, step down to a 63mm bore (1559N push), or step up to 100mm (3927N push) for heavier loads. Note that a standard cylinder drifts on air loss—the cushion only decelerates near stroke end—so fit an external rod lock or pilot-operated check valve for held loads. For self-switching needs, consider the SAUF valve-integrated variant.
Replacement checklist
Yes, the AirTAC SU80X80FA is discontinued and end-of-life. The direct replacement is the SAU80X80FA. It provides identical 80mm bore, 80mm stroke, 513kgf max force, 3/8 port, and SC-series FA mounting compatibility, fitting the same application envelope.
At 0.5MPa it pushes 2513N and pulls 2268N; at 0.7MPa push is 3518N, and the theoretical max is 513kgf at 1.0MPa. A plain cylinder does not hold a load without live air—the cushion only decelerates. For load holding, use an external rod lock or pilot-operated check valve.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X80FA replacement — usually within 7-8 hours.
