This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X150SFA, 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 SU80X150SFA
The AirTAC Airtac SU63-100 Standard Cylinder SU80X150SFA is a double-acting profile-type standard cylinder with a Ø80mm bore and 150mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X150SFA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X150SFA
The AirTAC SU80X150SFA is a discontinued double-acting profile cylinder with an 80mm bore and 150mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, with a 3/8" port and an M20x1.5 rod thread. The direct replacement is the SAU80X150SFA, matching the bore, stroke, output force, port size, and SC-series FA mounting. You get a direct upgrade without machining changes.
This compact extruded-aluminium body is shorter than an ISO 15552 cylinder of the same bore. The -S magnet on this legacy unit works with CS1-B/DS1-B switches, but the SAU replacement requires current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF built-in 4M solenoid valve option the SU never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X150SFA 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 SAU80X150SFA 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 SU80X150SFA Is Used
Carton Diverting
Uses the 150mm stroke to push heavy cardboard cartons cleanly across a transfer belt without overtravel.
Pallet Stopping
Deploys the FA mount to act as a robust pneumatic stop gate for inbound 128kg pallets on gravity rollers.
Press Ejection
Cycles rapidly at 30-800mm/s to eject dense formed parts from a press bed using the full 2513N thrust.
Replacing the Airtac SU63-100 Standard Cylinder SU80X150SFA with the SAU80X150SFA
To replace this SU80X150SFA, order the SAU80X150SFA. Confirm the 80mm bore, 150mm stroke, 3/8" port, M20x1.5 rod thread, and the SC-series FA mounting interface are retained. Because this SKU includes the -S magnet, note the sensor family changes: legacy CS1-B/DS1-B switches will not fit the SAU, so upgrade to CMSG/DMSG/EMSG sensors. If you need integrated flow control, explore the SAUF variant which adds a built-in valve the SU lacked. When sizing both ways, dropping to a 63mm bore gives 1559N push at 0.5MPa, while stepping up to 100mm yields 3927N. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for held loads. At 150mm stroke side-load risk is low, but always guide the rod for off-center forces.
Replacement checklist
- ✓ Same bore / stroke → SAU80X150SFA
- ✓ 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 SU80X150SFA FAQ
Yes, the SU80X150SFA is discontinued. The direct replacement is the SAU80X150SFA. It matches the 80mm bore, 150mm stroke, 2513N force, 3/8" port, and SC-series FA mounting. The only change is that your legacy CS1-B/DS1-B switches must be replaced with CMSG/DMSG/EMSG sensors.
The 80mm bore uses a fixed 3/8" port. It generates 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a theoretical maximum of 513kgf at 1.0MPa. The cushion only decelerates the load and does not hold it without live air.
