This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X680, 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 SU80X680
The AirTAC Airtac SU63-100 Standard Cylinder SU80X680 is a double-acting profile-type standard cylinder with a Ø80mm bore and 680mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X680, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X680
The AirTAC SU80X680 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 680 mm stroke. Delivering 2513 N push force at 0.5 MPa, it features an extruded aluminum barrel and adjustable air cushions, making it more compact than an ISO 15552 cylinder of the same bore. AirTAC ended this line, so the direct replacement is the SAU80X680, matching the exact bore, stroke, output force, 3/8 inch port, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade uses current CMSG/DMSG/EMSG switches for magnetized variants, and introduces the SAUF built-in 4M solenoid valve option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X680 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 SAU80X680 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 SU80X680 Is Used
Long-Stroke Diverting
Pushes heavy pallets laterally across transfer lines using the full 680 mm travel, relying on the 2513 N thrust at 0.5 MPa to overcome friction.
Automated Press Ejection
Ejects formed parts from machinery, using the adjustable 28 mm air cushions to decelerate the 80 mm piston smoothly at stroke ends.
Replacing the Airtac SU63-100 Standard Cylinder SU80X680 with the SAU80X680
To replace the discontinued SU80X680, order the SAU80X680 direct equivalent, verifying the 80 mm bore, 680 mm stroke, M20x1.5 rod thread, and 3/8 inch port. Since this specific SKU has no magnet (-S), it cannot support a sensor; if sensing is needed on the new unit, specify an SAU magnet and use CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B. If you need higher force, the 100 mm bore offers 3927 N push at 0.5 MPa; if less is required, the 63 mm bore provides 1559 N. With a 680 mm stroke, prevent rod bending by using an external guide to absorb side loads. Note that a standard cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU80X680
- ✓ 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 SU80X680 FAQ
Yes, the AirTAC SU80X680 is discontinued. The direct replacement is the SAU80X680. It shares the identical 80 mm bore, 680 mm stroke, output force, 3/8 inch port, and SC-series mounting accessories, so it fits the same application directly.
The 80 mm bore uses a 3/8 inch port and provides 2513 N push and 2268 N pull at 0.5 MPa. At 0.7 MPa the push force is 3518 N, and the theoretical maximum is 513 kgf at 1.0 MPa. The cylinder operates at speeds of 30-800 mm/s.
