This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X450S, 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 SU63X450S
The AirTAC SU63-100 Standard Cylinder SU63X450S 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 SAU63X450S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X450S
The AirTAC SU63X450S is a discontinued double-acting profile-type cylinder featuring a 63mm bore, 450mm stroke, and a 3/8" port. Delivering 1559 N of push force at 0.5 MPa, it uses an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this unit with the SAU63X450S, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades this to current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the original SU line never offered.

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 SAU63X450S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SU63-100 Standard Cylinder SU63X450S Is Used
Mid-Power Conveyor Diverting
Drives 450mm stroke diverting arms on packaging lines, utilizing the 1559 N push force at 0.5 MPa to reliably push heavy cartons to adjacent belts.
Long-Stroke Component Ejection
Ejects molded or machined parts from press beds, using the 450mm travel to clear large tooling envelopes while absorbing end-of-stroke impact via adjustable cushions.
Replacing the Airtac SU63-100 Standard Cylinder SU63X450S with the SAU63X450S
To replace the SU63X450S, order the SAU63X450S. Verify your 3/8" port thread (PT, G, or NPT), M16x1.5 rod-end connection, and SC-series mounting hardware (LB, FA, FB, CA, CB, TC, TCM1), as all remain identical for a direct. Because this model has the -S magnet, note that your legacy CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the SAU. Sizing context: a 50mm bore provides 982 N push at 0.5 MPa, while an 80mm bore yields 2513 N, so the 63mm bore's 1559 N is ideal for mid-range loads. With a 450mm stroke, prevent rod bending by using an external guide to absorb side loads. This cylinder will not hold a load on air loss; the 21mm adjustable cushions only decelerate the piston near the end caps, so add an external rod lock or pilot-operated check valve if load holding is required. For faster actuation, consider the SAUF63X450S variant with its integrated 4M valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X450S
- ✓ 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 SU63X450S FAQ
Yes, the SU63X450S is discontinued. The direct replacement is the AirTAC SAU63X450S. It shares the identical 63mm bore, 450mm stroke, 3/8" port, output force, and SC-series mounting accessories, so it fits the same application. You only need to update your sensors, as the SAU uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
The 3/8" port bore delivers a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. At 0.7 MPa it pushes 2182 N, and at 0.9 MPa it pushes 2805 N. The theoretical maximum force is 318 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s and features a 20mm piston rod with an M16x1.5 thread.
