This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X500STC, 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 SU80X500STC
The AirTAC Airtac SU63-100 Standard Cylinder SU80X500STC is a double-acting profile-type standard cylinder with a Ø80mm bore and 500mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X500STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X500STC
The AirTAC SU80X500STC is a discontinued double-acting profile-type cylinder with an 80mm bore and 500mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, making way for the direct replacement: the SAU80X500STC. The SAU matches the original 3/8 port, M20x1.5 rod thread, 28mm cushions, force, and SC-series TC mounting interface without any footprint changes.
This upgrade introduces modern CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches used on this -S magnet model, and the SAU line adds an optional SAUF built-in 4M valve the SU lacked. Note that a plain cylinder drifts on air loss; the cushions only decelerate near stroke end, so use an external rod lock for holding.

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 SAU80X500STC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SU63-100 Standard Cylinder SU80X500STC Is Used
Pallet Diversion
Handles heavy pallet routing on packaging lines, using the 2513N push force at 0.5MPa to deflect loads reliably without physical strain on the actuator body.
Press Ejection
Ejects formed metal or plastic parts from press beds, relying on the 28mm adjustable air cushions to decelerate the 80mm piston smoothly at the end of travel.
Replacing the Airtac SU63-100 Standard Cylinder SU80X500STC with the SAU80X500STC
To replace the discontinued SU80X500STC, order the SAU80X500STC, confirming the 80mm bore, 500mm stroke, 3/8 port, and TC mounting accessory are retained. If downsizing, a 63mm bore yields 1559N push at 0.5MPa; if upsizing, a 100mm bore provides 3927N. Because this is a 500mm stroke, prevent rod bending by guiding the load externally to avoid side-load forces. The -S piston magnet requires a sensor family change from the old CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches. For loads that must stay put during air loss or valve centering, add a pilot-operated check valve or external rod lock, as the standard cushion only decelerates. If integrating pneumatics directly, the SAUF variant offers a built-in valve the SU never had.
Replacement checklist
- ✓ Same bore / stroke → SAU80X500STC
- ✓ 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 SU80X500STC FAQ
Yes, the AirTAC SU80X500STC is discontinued and end-of-life. The direct replacement is the SAU80X500STC. It maintains the identical 80mm bore, 500mm stroke, 3/8 port, output force, and SC-series TC mounting, so it fits the same application directly.
At 0.5MPa it pushes 2513N and pulls 2268N; at 0.7MPa push is 3518N, and the theoretical maximum is 513kgf at 1.0MPa. Because this SKU uses a -S magnet, the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
