This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X300FB, 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 SU80X300FB
The AirTAC Airtac SU63-100 Standard Cylinder SU80X300FB 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 SAU80X300FB, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X300FB
The AirTAC SU80X300FB is a discontinued double-acting profile cylinder with an 80mm bore and 300mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa, making it a robust choice for heavy-duty actuation. AirTAC replaced this end-of-line unit with the SAU80X300FB, a direct replacement retaining the exact bore, stroke, force, 3/8" port, and SC-series FB mounting interface.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a SAUF built-in-valve option the SU lacked. Note this SKU lacks a magnet and cannot accept switches. The 300mm stroke requires external guides to prevent rod bending under side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X300FB 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 SAU80X300FB 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 SU80X300FB Is Used
Heavy Material Diversion
Actuates large sorting arms on high-throughput packaging lines, utilizing the 2513N push force at 0.5MPa to deflect heavy cartons reliably.
Pallet Positioning Gates
Drives heavy-duty indexing gates in automated warehouses, where the 300mm stroke and FB mounting provide stable, long-travel material routing.
Press Ejection Systems
Ejects formed metal or composite parts from industrial presses, requiring the robust 80mm bore output and external guide support for the 300mm extension.
Replacing the Airtac SU63-100 Standard Cylinder SU80X300FB with the SAU80X300FB
To replace this discontinued SU80X300FB, order the SAU80X300FB direct equivalent, verifying the 80mm bore, 300mm stroke, 3/8" port, M20x1.5 rod thread, and FB mounting. Because this SKU has no magnet (-S), it cannot support sensing; if detection is needed, specify an SAU80X300FBS and migrate to CMSG/DMSG/EMSG switches. For load holding, note that the air cushion only decelerates the piston and will not hold a load on air loss—install an external rod lock or pilot-operated check valve. At 300mm stroke, use external guides to prevent rod bending. If downsizing, a 63mm bore yields 1559N push at 0.5MPa; if upsizing, a 100mm bore provides 3927N.
Replacement checklist
- ✓ Same bore / stroke → SAU80X300FB
- ✓ 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 SU80X300FB FAQ
Yes, the AirTAC SU80X300FB is discontinued. The direct replacement is the SAU80X300FB. It matches the original 80mm bore, 300mm stroke, 513kgf max force, 3/8" port, and FB mounting, so it drops directly into the same application.
This double-acting cylinder provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and a 513kgf maximum at 1.0MPa. This specific SKU lacks a magnet and cannot accept switches. The SAU replacement supports CMSG/DMSG/EMSG sensors if sensing is required.
