This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X50FB, 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 SU80X50FB
The AirTAC Airtac SU63-100 Standard Cylinder SU80X50FB is a double-acting profile-type standard cylinder with a Ø80mm bore and 50mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X50FB, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X50FB
The AirTAC SU80X50FB is a discontinued double-acting profile-type cylinder with an 80mm bore and 50mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa, making way for the exact SAU80X50FB direct replacement. The SAU maintains the same extruded aluminium body, 3/8" port, M20x1.5 rod thread, and SC-series FB mounting, ensuring a seamless swap.
Because this SKU lacks a magnet (-S), it cannot accept a sensor. The SAU upgrade uses current CMSG/DMSG/EMSG switches for magnetised variants, and introduces the SAUF built-in 4M valve option absent in the SU line.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X50FB 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 SAU80X50FB 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 SU80X50FB Is Used
Heavy-Duty Clamping
Secures large metal castings during machining using the 2513 N push force at 0.5 MPa, leveraging the rigid FB mount to resist offset loads.
Pallet Diverting
Pushes heavy loaded pallets off a main conveyor line, where the 128 kg vertical lift capacity and compact profile body fit tight transfer spaces.
Carton Flap Folding
Folds thick cardboard flaps on oversized packaging lines, utilising the 28 mm adjustable air cushion to soften impact at the 50mm stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU80X50FB with the SAU80X50FB
To replace the SU80X50FB, order the SAU80X50FB direct equivalent, verifying the 80mm bore, 50mm stroke, 3/8" port, and FB front-back mounting accessory are retained. If sizing alternatives, neighbouring bores (63mm or 100mm) alter the 3518 N push at 0.7 MPa. Without a magnet, this cylinder cannot take a sensor; if sensing is needed, specify an -S SAU model and update to CMSG/DMSG/EMSG switches. Note that a plain cylinder drifts without live air—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for held loads. The SAUF valve-integrated variant is available if self-switching is required.
Replacement checklist
- ✓ Same bore / stroke → SAU80X50FB
- ✓ 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 SU80X50FB FAQ
Yes, the SU80X50FB is discontinued. The direct replacement is the SAU80X50FB. It shares the identical 80mm bore, 50mm stroke, 3/8" port, output force, and SC-series FB mounting, so it fits the same application directly.
The bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical max of 513 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor; magnetised SAU replacements use CMSG/DMSG/EMSG switches.
