This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X1250S, 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 SU80X1250S
The AirTAC SU63-100 Standard Cylinder SU80X1250S is a double-acting profile-type standard cylinder with a Ø80mm bore and 1250mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X1250S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X1250S
The AirTAC SU80X1250S is a discontinued double-acting profile-type cylinder with an 80mm bore and 1250mm stroke. It delivers 2513N push force at 0.5MPa and features a 3/8" port. AirTAC replaced this unit with the SAU80X1250S, a direct alternative retaining the exact body, force, and SC-series mounting.
The SAU upgrade transitions the -S magnet to current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches, and introduces the SAUF valve-integrated variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X1250S 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 SAU80X1250S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 80 | Bore size in mm. |
| ×1250 | 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 SU80X1250S Is Used
Long-Stroke Diversion
Pushes heavy pallets across 1250mm transfer lines using the 2513N thrust at 0.5MPa.
Automated Press Ejection
Ejects dense parts from machinery, utilizing the 80mm bore's 513kgf maximum theoretical force.
Replacing the Airtac SU63-100 Standard Cylinder SU80X1250S with the SAU80X1250S
To replace the SU80X1250S, order the SAU80X1250S direct equivalent, verifying the 80mm bore, 1250mm stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting. Because the -S magnet is present, note that the legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. For loads needing 3518N at 0.7MPa, the 80mm bore fits, while a 63mm bore offers 2182N if downsizing. A plain cylinder drifts without live air; use an external rod lock for holding. At 1250mm, prevent rod bending by using external guides to manage side loads. The SAUF variant adds a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU80X1250S
- ✓ 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 SU80X1250S FAQ
Yes, the SU80X1250S is discontinued. The direct replacement is the SAU80X1250S, which shares the same 80mm bore, 1250mm stroke, 2513N force, 3/8" port, and SC-series mounting.
At 0.5MPa it pushes 2513N and pulls 2268N; at 0.7MPa it pushes 3518N, with a 513kgf max at 1.0MPa. The -S magnet used legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
