This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X380S, 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 SU80X380S
The AirTAC SU63-100 Standard Cylinder SU80X380S 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 SAU80X380S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X380S
The AirTAC SU80X380S is a discontinued double-acting profile-type cylinder featuring an extruded aluminium barrel and a 380 mm stroke. Delivering 2513 N of push force at 0.5 MPa, it is replaced directly by the SAU80X380S. This direct upgrade matches the 80 mm bore, 25 mm rod, 3/8" port, output force and SC-series mounting. The compact profile body is shorter than a same-bore ISO 15552 unit.
Because this SKU includes the -S magnet, it originally used legacy CS1-B/DS1-B switches. The SAU80X380S successor transitions to current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve, a self-switching option the SU line never offered. Operating pressure is 0.15-1.0 MPa, with adjustable 28 mm cushions at both ends.

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 SAU80X380S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 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 SU80X380S Is Used
Pallet Diversion
Pushes heavy pallets laterally across conveyor lines using the 2513 N push force at 0.5 MPa, with external guides handling the 380 mm travel.
Press Ejection
Ejects formed metal or plastic components from press beds, utilising the 28 mm adjustable end cushions to decelerate the 25 mm rod smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU80X380S with the SAU80X380S
To replace this discontinued SU80X380S, order the SAU80X380S direct equivalent. Verify your 3/8" port threads (PT, G or NPT), M20x1.5 rod-end connection, and SC-series mounting hardware (LB, FA, FB, CA, CB). Since this model has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG on the new SAU unit. For sizing alternatives, dropping to a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to 100 mm provides 3927 N. At 380 mm stroke, prevent side-load and rod-bending issues by fitting external guide rails to support the load. A plain cylinder does not hold load without live air; the cushions only decelerate. For secure holding on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU80X380S
- ✓ 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 SU80X380S FAQ
Yes, the SU80X380S is discontinued. The direct replacement is the SAU80X380S. It shares the same 80 mm bore, 380 mm stroke, 3/8" port, output force and SC-series mounting accessories. The main upgrade is that the SAU uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 3/8" port bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. Operating speed is 30-800 mm/s, with a 25 mm piston rod and M20x1.5 thread.
