This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X670S, 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 SU80X670S
The AirTAC SU63-100 Standard Cylinder SU80X670S is a double-acting profile-type standard cylinder with a Ø80mm bore and 670mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X670S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X670S
The AirTAC SU80X670S is a discontinued double-acting profile cylinder with an extruded aluminum barrel and adjustable air cushions at both ends. The direct replacement is the SAU80X670S, matching the 80 mm bore, 670 mm stroke, 513 kgf max force, 3/8" port and SC-series mounting.
During the upgrade, the body dimensions and performance remain unchanged, but the -S piston magnet now pairs with current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, a self-switching option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X670S 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 SAU80X670S 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 SU80X670S Is Used
Pallet Diversion
Handles heavy pallets on packaging lines, using the 2513 N push force at 0.5 MPa to divert loads weighing up to 1508 N safely onto adjacent tracks.
Material Lowering
Lowers stacked components with a vertical lift capacity around 128 kg, requiring an external guide to manage the 670 mm stroke and prevent rod bending.
Press Ejection
Ejects formed metal or plastic parts from press beds, relying on adjustable 28 mm air cushions to decelerate the 25 mm rod smoothly at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU80X670S with the SAU80X670S
To replace this discontinued SU80X670S, order the SAU80X670S direct equivalent, verifying the 80 mm bore, 670 mm stroke, 3/8" port, M20x1.5 rod thread and SC-series mounting (LB/FA/FB/CA/CB). Because the -S magnet is present, note that the legacy CS1-B/DS1-B switches must change to the CMSG/DMSG/EMSG family on the new SAU cylinder. For sizing both ways, a 63 mm bore provides 1559 N push at 0.5 MPa, while a 100 mm bore offers 3927 N; alternatively, pushing this 80 mm bore to 0.7 MPa yields 3518 N. A plain cylinder does not hold load without live air, so for vertical applications add an external rod lock or pilot-operated check valve. Finally, at 670 mm stroke, prevent rod bending by guiding the load externally to avoid side-load stress.
Replacement checklist
- ✓ Same bore / stroke → SAU80X670S
- ✓ 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 SU80X670S FAQ
Yes, the SU80X670S is discontinued. The direct replacement is the SAU80X670S, which shares the same 80 mm bore, 670 mm stroke, 3/8" port, output force and SC-series mounting.
The bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf maximum at 1.0 MPa. The -S magnet on this legacy SU used CS1-B/DS1-B switches, but the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
