This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X650, 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 SU80X650
The AirTAC Airtac SU63-100 Standard Cylinder SU80X650 is a double-acting profile-type standard cylinder with a Ø80mm bore and 650mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X650, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X650
The AirTAC SU80X650 is a discontinued double-acting profile-type cylinder with an 80mm bore and 650mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, making it a robust choice for heavy-duty actuation. The direct replacement is the SAU80X650, which preserves the original 3/8 inch port, M20x1.5 rod thread, output force, and SC-series mounting dimensions.
Because this is a non-magnet SKU, it cannot accept a position sensor. If sensing is needed on the SAU upgrade, you must select an -S model and migrate from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

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 SAU80X650 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 SU80X650 Is Used
Heavy Material Diversion
Handles large package routing on heavy-duty conveyor lines using its 2513N push force to reliably pivot or deflect bulky goods.
Press Ejection Systems
Ejects dense manufactured parts from press beds, utilizing the 80mm bore and adjustable 28mm cushions to absorb end-of-stroke impact.
Replacing the Airtac SU63-100 Standard Cylinder SU80X650 with the SAU80X650
To replace this discontinued SU80X650, order the SAU80X650 direct equivalent, confirming the 80mm bore, 650mm stroke, 3/8 inch port, and default PT threads. If you need position sensing, note that this specific no-magnet SKU cannot accept a switch; you must upgrade to an SAU80X650-S and adopt the modern CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. When sizing, the 80mm bore yields 2513N push at 0.5MPa, while the neighboring 63mm bore offers 1559N; choose the 80mm for loads near 1508N safe working capacity. A plain cylinder drifts without live air, so add an external rod lock or pilot-operated check valve for load holding. Finally, the 650mm stroke requires external guide rails to prevent rod bending under side loads. The SAUF valve-integrated variant is also available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU80X650
- ✓ 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 SU80X650 FAQ
Yes, the AirTAC SU80X650 is discontinued. The direct replacement is the SAU80X650. It shares the identical 80mm bore, 650mm stroke, 3/8 inch port, output force, and SC-series mounting hardware, allowing a direct physical swap without machine modifications.
This double-acting 80mm bore cylinder provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a maximum theoretical force of 513kgf at 1.0MPa. Because this specific SKU lacks a magnet, it cannot accept position switches; the SAU-S replacement uses CMSG/DMSG/EMSG sensors.
