This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X270, 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 SU80X270
The AirTAC Airtac SU63-100 Standard Cylinder SU80X270 is a double-acting profile-type standard cylinder with a Ø80mm bore and 270mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X270, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X270
The AirTAC SU80X270 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 270 mm stroke. Delivering 2513 N of push force at 0.5 MPa, it features an extruded aluminum barrel and adjustable air cushions at both ends, making it more compact than a standard ISO 15552 unit of the same bore. AirTAC replaced this end-of-life unit with the SAU80X270, a direct replacement retaining the exact same body dimensions, 3/8" port, M20x1.5 rod thread, and SC-series mounting compatibility.
Because this specific SKU lacks a magnet, it cannot accept position sensors. Upgrading to the SAU80X270 allows you to add current CMSG, DMSG, or EMSG switches if needed, whereas the legacy SU line relied on older CS1-B or DS1-B reed switches. Note that a standard cylinder drifts without live air; use an external rod lock or pilot-operated check valve for secure load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X270 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 SAU80X270 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 SU80X270 Is Used
Pallet Diversion
Actuates heavy divert arms on packaging conveyors, utilizing the 2513 N push force at 0.5 MPa to redirect loaded pallets smoothly with adjustable end cushions.
Material Ejection
Provides robust ejection force for compressed goods or scrap material out of staging bins, where the 80 mm bore and 270 mm stroke offer the necessary reach and power.
Press Clamping
Secures heavy workpieces in light assembly presses, taking advantage of the compact profile body to fit within tight machine frames while delivering reliable clamping pressure.
Replacing the Airtac SU63-100 Standard Cylinder SU80X270 with the SAU80X270
To replace the discontinued SU80X270, order the SAU80X270 direct equivalent, verifying your 3/8" port threads (PT, G, or NPT) and SC-series mounting brackets (LB, FA, FB, CA, CB, or TC). This 80 mm bore generates 2513 N push at 0.5 MPa; if you need less force, step down to a 63 mm bore (1559 N push), or step up to 100 mm (3927 N push) for heavier loads. Since this SKU has no magnet (-S), it cannot support sensing; if your application requires position detection, the SAU replacement allows you to use modern CMSG, DMSG, or EMSG switches. Furthermore, the SAU family offers a SAUF variant with a built-in 4M solenoid valve for self-switching, an option the original SU line lacked. At 270 mm stroke, ensure adequate guidance to prevent rod bending and side-load damage. Finally, remember that air cushions only decelerate the piston at end-of-stroke; they do not hold the load, so install a pilot-operated check valve or external rod lock if dropping is a concern.
Replacement checklist
- ✓ Same bore / stroke → SAU80X270
- ✓ 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 SU80X270 FAQ
Yes, the SU80X270 is discontinued and end-of-life. The direct replacement is the AirTAC SAU80X270. It features the exact same 80 mm bore, 270 mm stroke, 2513 N output force, 3/8" port size, and SC-series mounting footprint. You can install the SAU80X270 directly into your existing fixture without modifying the mounting hardware.
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At 0.7 MPa it pushes 3518 N, and the theoretical maximum force is 513 kgf at 1.0 MPa. This specific SU80X270 SKU lacks a magnet, meaning it cannot accept position sensors. If sensing is required, the SAU80X270 replacement supports modern CMSG, DMSG, or EMSG switches, whereas the legacy SU line used older CS1-B or DS1-B switches.
