This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X80, 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 SU80X80
The AirTAC SU63-100 Standard Cylinder SU80X80 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 SAU80X80, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X80
The AirTAC SU80X80 is a discontinued double-acting profile cylinder featuring an extruded aluminum barrel and adjustable air cushions at both ends. Delivering 2513 N of push force at 0.5 MPa via a 3/8 inch port, it is replaced directly by the SAU80X80.
The SAU80X80 direct retains the exact 80 mm bore, 80 mm stroke, output force, and SC-series mounting. Two key upgrades exist: the SAU uses modern CMSG/DMSG/EMSG sensors instead of legacy CS1-B/DS1-B switches, and the SAUF variant adds a built-in valve. Note this no-magnet SKU cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X80 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 SAU80X80 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 SU80X80 Is Used
Pallet Diversion
Pushes heavy pallets transversely off a high-throughput line using 2513 N of thrust at 0.5 MPa.
Press Ejection
Ejects dense formed parts from a press bed, utilizing the 28 mm adjustable cushions to absorb kinetic energy.
Replacing the Airtac SU63-100 Standard Cylinder SU80X80 with the SAU80X80
To replace this SU80X80, order the SAU80X80 with the same 80 mm stroke, 3/8 inch port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this specific SKU lacks a magnet, it cannot support sensing; if you need position detection, select an SAU80X80S and migrate to CMSG/DMSG/EMSG switches. Sizing context: the 80 mm bore yields 2513 N push at 0.5 MPa, sitting between the 63 mm (1559 N) and 100 mm (3927 N) bores. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the cushion only decelerates. If you want to simplify plumbing, consider the SAUF80X80 built-in valve variant.
Replacement checklist
- ✓ Same bore / stroke → SAU80X80
- ✓ 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 SU80X80 FAQ
Yes, the SU80X80 is discontinued. The direct replacement is the AirTAC SAU80X80, which matches the 80 mm bore, 80 mm stroke, 3/8 inch port, force, and SC-series mounting.
It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a maximum theoretical force of 513 kgf at 1.0 MPa. This non-magnet SKU cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
