This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X810S, 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 SU80X810S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X810S is a double-acting profile-type standard cylinder with a Ø80mm bore and 810mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X810S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X810S
The AirTAC SU80X810S is a discontinued double-acting profile-type cylinder featuring an 80mm bore, 810mm stroke, and a 3/8" port. Delivering 2513 N of push force at 0.5 MPa, it uses an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same size. AirTAC replaced this unit with the SAU80X810S, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting accessories.
When upgrading to the SAU80X810S, your CS1-B and DS1-B switches are replaced by the current CMSG, DMSG, or EMSG sensor families. The new SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X810S 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 SAU80X810S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×810 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU80X810S Is Used
Long-Stroke Diversion
Ideal for pushing heavy pallets off a main conveyor line over an 810mm extension using the 2513 N push force at 0.5 MPa.
Large Press Ejection
Ejects bulky formed parts from large stamping presses, relying on the 80mm bore and 28mm adjustable cushions to absorb impact.
Replacing the Airtac SU63-100 Standard Cylinder SU80X810S with the SAU80X810S
To replace the SU80X810S, order the SAU80X810S and verify your 80mm bore, 810mm stroke, 3/8" port, and M20x1.5 rod thread. Because this unit has the -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. If you need integrated control, consider the SAUF valve-integrated variant. For loads requiring holding on air loss, add an external rod lock or pilot-operated check valve, as the adjustable cushions only decelerate. With an 810mm stroke, external guides are recommended to prevent rod bending and side-load damage. If you need more force, the 100mm bore offers 3927 N push at 0.5 MPa; if less is acceptable, the 63mm bore provides 1559 N.
Replacement checklist
- ✓ Same bore / stroke → SAU80X810S
- ✓ 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 SU80X810S FAQ
Yes, the SU80X810S is discontinued. The direct replacement is the AirTAC SAU80X810S. It matches the 80mm bore, 810mm stroke, force, 3/8" port, and SC-series mounting, so it fits the same application without mechanical changes.
The 80mm bore provides 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. Because this is an -S model, the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the new SAU.
