This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X25, 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 SU80X25
The AirTAC Airtac SU63-100 Standard Cylinder SU80X25 is a double-acting profile-type standard cylinder with a Ø80mm bore and 25mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X25, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X25
The AirTAC SU80X25 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 25 mm stroke. It delivers 2513 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU80X25, a direct sharing the exact body, force, and SC-series mounting.
This compact extruded barrel is shorter than same-bore ISO 15552 units. The SAU upgrade switches to CMSG/DMSG/EMSG sensors and adds a SAUF valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X25 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 SAU80X25 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU80X25
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×25 | 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 SU80X25 Is Used
Short-Stroke Clamping
Ideal for high-force 25 mm clamping tasks in machining fixtures, utilizing the 2513 N push capacity at 0.5 MPa to secure heavy steel components.
Transfer Diverters
Drives robust diverting arms on packaging lines, where the compact profile body saves space without sacrificing the 513 kgf maximum theoretical output.
Replacing the Airtac SU63-100 Standard Cylinder SU80X25 with the SAU80X25
To replace this SU80X25, order the SAU80X25 with the same 80 mm bore, 25 mm stroke, 3/8" port, M20x1.5 rod thread, and SC-series mount. Because this specific SKU lacks a magnet (-S), it cannot accept a sensor. If you need position detection on the SAU, specify the -S option and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For sizing, the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Note that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve to hold loads securely.
Replacement checklist
- ✓ Same bore / stroke → SAU80X25
- ✓ 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 SU80X25 FAQ
Yes, the AirTAC SU80X25 is discontinued. The direct replacement is the SAU80X25, which maintains the identical 80 mm bore, 25 mm stroke, 3/8" port, output force, and SC-series mounting accessories.
The 80 mm bore yields 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf maximum at 1.0 MPa. The air cushions only decelerate the piston; they do not hold a load. For load holding on air loss, install an external rod lock or pilot-operated check valve.
