This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X25S, 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 SU80X25S
The AirTAC Airtac SU63-100 Standard Cylinder SU80X25S 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 SAU80X25S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X25S
The AirTAC SU80X25S is a discontinued double-acting profile-type cylinder with an 80mm bore and 25mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, utilizing a 25mm rod and 3/8" port. AirTAC replaced this unit with the SAU80X25S, a direct upgrade retaining the exact bore, stroke, output force, and SC-series mounting footprint.
This compact extruded-aluminium body is shorter than an ISO 15552 cylinder of the same bore. The -S magnet on this legacy unit worked with CS1-B/DS1-B switches; the SAU replacement uses modern CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF built-in-valve option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X25S 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 SAU80X25S 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 SU80X25S Is Used
Short-Stroke Clamping
Ideal for high-force 25mm clamping tasks in machining fixtures, utilizing the 2513N push at 0.5MPa to secure heavy steel billets firmly.
Transfer Line Stops
Provides robust stopping power on heavy-duty material handling lines, where the compact profile body saves space along the conveyor frame.
Press Ejection
Delivers rapid 30-800mm/s ejection of finished parts from stamping presses, absorbing end-of-stroke impact with 28mm adjustable cushions.
Replacing the Airtac SU63-100 Standard Cylinder SU80X25S with the SAU80X25S
To replace this SU80X25S, order the SAU80X25S. Confirm your 3/8" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) are unchanged. Because this SKU has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. If sizing alternatives, the neighbouring 63mm bore yields 1559N push at 0.5MPa, while the 100mm bore yields 3927N. A plain cylinder drifts without live air; the cushions only decelerate, so add an external rod lock for held loads. The SAUF valve-integrated variant is available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU80X25S
- ✓ 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 SU80X25S FAQ
Yes, the SU80X25S is discontinued. The direct replacement is the SAU80X25S. It matches the 80mm bore, 25mm stroke, 3/8" port, 513kgf max force, and SC-series mounting accessories, so it fits the same application directly.
It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf max at 1.0MPa. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAU80X25S replacement upgrades this to CMSG/DMSG/EMSG sensors.
