This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X405S, 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 SU63X405S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X405S is a double-acting profile-type standard cylinder with a Ø63mm bore and 405mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X405S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X405S
The AirTAC SU63X405S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 405 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa, peaking at a theoretical 318 kgf. AirTAC replaced this unit with the SAU63X405S, a direct sharing the exact bore, stroke, 3/8" port, M16x1.5 rod thread and SC-series mounting.
Because this SKU includes a magnet, it originally used legacy CS1-B/DS1-B switches; the SAU successor upgrades you to current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve the SU 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 SAU63X405S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×405 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SU63X405S Is Used
Pallet Diversion
Pushes heavy pallets sideways off a main conveyor line using 1559 N of thrust at 0.5 MPa, with the 405 mm stroke clearing guide rails.
Press Ejection
Ejects formed metal parts from a press bed, where the compact extruded profile saves space compared to older ISO 15552 units.
Replacing the Airtac SU63-100 Standard Cylinder SU63X405S with the SAU63X405S
To replace this unit, order the SAU63X405S. Confirm your 3/8" port thread (PT, G or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, TC) carry over directly. Since this is an -S magnet model, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the new cylinder. For load holding, remember the air cushion only decelerates; without live air the piston drifts, so fit an external rod lock or pilot-operated check valve. At 405 mm, this long stroke risks rod bending under side loads—use external guides. If you need less force, a 50 mm bore gives 982 N push at 0.5 MPa; if you need more, an 80 mm bore yields 2513 N. You can also explore the SAUF for integrated valve control.
Replacement checklist
- ✓ Same bore / stroke → SAU63X405S
- ✓ 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 SU63X405S FAQ
Yes, the SU63X405S is discontinued. The direct replacement is the AirTAC SAU63X405S. It shares the same 63 mm bore, 405 mm stroke, 318 kgf max force, 3/8" port and SC-series mounting. The only change is that your -S magnet model's legacy CS1-B/DS1-B switches must be upgraded to CMSG/DMSG/EMSG sensors on the new SAU cylinder.
The 63 mm bore generates 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and 2805 N push at 0.9 MPa, with a theoretical max of 318 kgf at 1.0 MPa. Operating speed is 30-800 mm/s. The 3/8" port, 20 mm rod, M16x1.5 thread and 21 mm cushions remain identical on the SAU replacement.
