This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X400S, 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 SU80X400S
The AirTAC SU63-100 Standard Cylinder SU80X400S is a double-acting profile-type standard cylinder with a Ø80mm bore and 400mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X400S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X400S
The AirTAC SU80X400S is a discontinued double-acting profile-type cylinder with an 80mm bore and 400mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, peaking at a theoretical 513kgf. AirTAC replaced this unit with the SAU80X400S, a direct upgrade retaining the exact 3/8 port, M20x1.5 rod thread, and SC-series mounting compatibility.
Because this SKU includes the -S magnet, it originally used legacy CS1-B/DS1-B switches; the SAU replacement transitions to current CMSG/DMSG/EMSG sensors. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore. Note the SAU line also adds a SAUF variant with a built-in valve, an option the SU series lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X400S 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 SAU80X400S 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 SU80X400S Is Used
Heavy Package Diversion
Pushes heavy pallets or totes across transfer lines using the 2513N push force at 0.5MPa, with the 400mm stroke clearing wide belt gaps.
Pallet Positioning
Indexes loaded pallets into stretch-wrap or labeling stations, where the 128kg vertical lift capacity handles substantial weight safely.
Press Ejection
Ejects formed metal or plastic parts from mid-sized presses, utilizing the adjustable 28mm cushions to stop heavy loads smoothly at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU80X400S with the SAU80X400S
To replace this SU80X400S, order the SAU80X400S, verifying your 80mm bore, 400mm stroke, 3/8 port, and SC-series mounting hardware (LB/FA/FB/CA/CB). If relying on the -S magnet, remember the SAU uses CMSG/DMSG/EMSG switches instead of the older CS1-B/DS1-B. If you need less force, step down to a 63mm bore (1559N push at 0.5MPa); if you need more, an 100mm bore provides 3927N. For the 400mm stroke, use external guides to prevent rod bending under side loads. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for load holding. The SAUF valve-integrated variant is available if you want to eliminate external piping.
Replacement checklist
- ✓ Same bore / stroke → SAU80X400S
- ✓ 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 SU80X400S FAQ
Yes, the SU80X400S is discontinued. The direct replacement is the SAU80X400S, which matches the 80mm bore, 400mm stroke, 2513N force, 3/8 port, and SC-series mounting. You simply order the SAU80X400S.
It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf max at 1.0MPa. The -S magnet works with legacy CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
