This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X380SFA, 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 SU80X380SFA
The AirTAC Airtac SU63-100 Standard Cylinder SU80X380SFA is a double-acting profile-type standard cylinder with a Ø80mm bore and 380mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X380SFA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X380SFA
The AirTAC SU80X380SFA is a discontinued double-acting profile-type cylinder with an 80mm bore and 380mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, utilizing a 3/8" port and M20x1.5 rod thread. AirTAC replaced this end-of-line unit with the SAU80X380SFA, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series FA mounting accessory.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches used on this -S SKU, and offers a new SAUF built-in-valve variant. Note that air cushions only decelerate the piston; an external rod lock is required to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X380SFA 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 SAU80X380SFA 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 SU80X380SFA
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×380 | 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 SU80X380SFA Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line using 2513N thrust at 0.5MPa, with the 380mm stroke clearing adjacent lanes.
Material Press
Holds composite sheets in a pressing fixture, requiring an external rod lock since the standard air cushion only decelerates at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU80X380SFA with the SAU80X380SFA
To replace this SU80X380SFA, order the SAU80X380SFA, confirming the 80mm bore, 380mm stroke, 3/8" port, and FA mounting. If sizing both ways, the adjacent 63mm bore yields 1559N push at 0.5MPa, while the 100mm bore provides 3927N. Because this is a 380mm stroke, use external guides to prevent rod bending and side-load wear. The -S magnet means you must migrate from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. The cushion only decelerates; use a pilot-operated check valve for load holding. The SAUF valve-integrated option can simplify plumbing.
Replacement checklist
- ✓ Same bore / stroke → SAU80X380SFA
- ✓ 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 SU80X380SFA FAQ
Yes, the SU80X380SFA is discontinued. The direct replacement is the SAU80X380SFA, which shares the same 80mm bore, 380mm stroke, 3/8" port, and SC-series FA mounting. You simply order the SAU equivalent.
It provides 2513N push and 2268N pull at 0.5MPa, 3518N at 0.7MPa, and a 513kgf maximum at 1.0MPa. The -S magnet on this SU worked with CS1-B/DS1-B switches; the SAU replacement requires the newer CMSG/DMSG/EMSG sensor family.
