This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X300, 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 SU80X300
The AirTAC SU63-100 Standard Cylinder SU80X300 is a double-acting profile-type standard cylinder with a Ø80mm bore and 300mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X300, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X300
The AirTAC SU80X300 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 300 mm stroke. It delivers 2513 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU80X300 direct replacement, matching the exact bore, stroke, output force, port size, and SC-series mounting accessories.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade adds modern CMSG/DMSG/EMSG switch compatibility and an optional SAUF built-in valve. Note the 300 mm stroke requires external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X300 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 SAU80X300 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 SU80X300 Is Used
Heavy Material Diversion
Pushes heavy pallets or workpieces off a main conveyor line using the 2513 N push force at 0.5 MPa, requiring the 300 mm stroke to clear the belt path.
Pallet Stopper Gate
Acts as a robust pneumatic stop for inbound pallets, absorbing kinetic energy via the 28 mm adjustable cushions before the load reaches the end cap.
Vertical Press Assembly
Provides downward clamping pressure for component seating, though an external rod lock must be fitted to prevent drift if air pressure drops.
Replacing the Airtac SU63-100 Standard Cylinder SU80X300 with the SAU80X300
To replace this discontinued SU80X300, order the SAU80X300 direct. Verify your 3/8" port, M20x1.5 rod thread, and SC-series mounts. This non-magnetic SKU cannot hold a load without live air; the cushions only decelerate, so add a pilot-operated check valve or rod lock for vertical holding. For the 300 mm stroke, use external guides to prevent rod bending. If you need more force, the 100 mm bore offers 3927 N at 0.5 MPa; if less is needed, the 63 mm bore provides 1559 N. The SAUF variant integrates a valve if desired.
Replacement checklist
- ✓ Same bore / stroke → SAU80X300
- ✓ 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 SU80X300 FAQ
Yes, the AirTAC SU80X300 is discontinued. The direct replacement is the SAU80X300, which shares the identical 80 mm bore, 300 mm stroke, 3/8" port, and SC-series mounting hardware.
At 0.5 MPa it pushes 2513 N and pulls 2268 N. It pushes 3518 N at 0.7 MPa and 4523 N at 0.9 MPa, with a 513 kgf maximum at 1.0 MPa. This specific SKU has no magnet, so it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
