This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X450SFB, 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 SU63X450SFB
The AirTAC SU63-100 Standard Cylinder SU63X450SFB is a double-acting profile-type standard cylinder with a Ø63mm bore and 450mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X450SFB, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X450SFB
The AirTAC SU63X450SFB is a discontinued double-acting profile-type cylinder with a 63mm bore and 450mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa, making it a robust choice for mid-heavy automation. AirTAC replaced this end-of-life unit with the SAU63X450SFB, a direct replacement retaining the exact bore, stroke, 3/8" port, M16x1.5 rod thread, and FB mounting interface.
The SAU upgrade keeps the compact extruded aluminum body—shorter than a same-bore ISO 15552 cylinder—while modernizing the sensor groove. Your legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU, and the new SAUF variant offers a built-in 4M valve the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X450SFB carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X450SFB 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 SU63X450SFB Is Used
Pallet Diversion
Uses the 1559N push force at 0.5MPa to deflect heavy pallets along a sorting line without requiring maximum system pressure.
Material Pressing
Applies consistent downward clamping force over the 450mm travel, relying on the adjustable 21mm cushions to soften the end impact.
Package Indexing
Pushes goods into staging lanes where the compact profile body saves valuable floor space compared to standard ISO cylinders.
Replacing the Airtac SU63-100 Standard Cylinder SU63X450SFB with the SAU63X450SFB
To replace this SU63X450SFB, order the SAU63X450SFB, confirming the 63mm bore, 450mm stroke, 3/8" port, and SC-series FB mount. Because this SKU includes the -S magnet, note that your old CS1-B/DS1-B switches will not fit the SAU; you must upgrade to CMSG/DMSG/EMSG sensors. If your application needs integrated control, explore the SAUF variant which adds a built-in 4M solenoid valve. For sizing alternatives, dropping to a 50mm bore yields 982N push at 0.5MPa, while stepping up to an 80mm bore provides 2513N. At 450mm stroke, prevent rod bending by using an external guide to absorb side loads. Remember, the air cushion only decelerates the piston; it does not hold the load on air loss, so add an external rod lock or pilot-operated check valve for vertical safety.
Replacement checklist
- ✓ Same bore / stroke → SAU63X450SFB
- ✓ 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 SU63X450SFB FAQ
Yes, the SU63X450SFB is discontinued. The direct replacement is the SAU63X450SFB, which shares the identical 63mm bore, 450mm stroke, 3/8" port, output force, and FB mounting. You will need to upgrade your sensors, as the SAU uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
This double-acting cylinder has a 3/8" air port. It generates 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, 2805N push at 0.9MPa, and a theoretical maximum of 318kgf at 1.0MPa.
