This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X600, 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 SU63X600
The AirTAC Airtac SU63-100 Standard Cylinder SU63X600 is a double-acting profile-type standard cylinder with a Ø63mm bore and 600mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X600, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X600
The AirTAC SU63X600 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 600 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa through a 3/8" port. AirTAC replaced this EOL unit with the SAU63X600, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
Because this SKU lacks a magnet, it cannot accept a sensor. If sensing is needed, the SAU upgrade uses modern CMSG/DMSG/EMSG switches, whereas legacy SU units required CS1-B/DS1-B types. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X600 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 SAU63X600 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 SU63X600 Is Used
Long-Stroke Diverting
Pushes packages across a 600 mm conveyor lane using the 1559 N thrust at 0.5 MPa, relying on external guides to prevent rod bending.
Pallet Push-Off
Acts as a double-acting ejector for staged pallets, moving loads safely under the 935 N working load limit with SC-series mounts.
Material Transfer
Shifts workpieces between machining stations over a 600 mm gap, benefiting from adjustable 21 mm cushions to brake the end-of-stroke impact.
Replacing the Airtac SU63-100 Standard Cylinder SU63X600 with the SAU63X600
To replace the SU63X600, order the SAU63X600 and verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware. Since this specific SKU has no magnet (-S), it cannot support position sensing; if you require switches, migrate to the SAU and use CMSG/DMSG/EMSG sensors. If your application needs self-switching, explore the SAUF valve-integrated profile body. Sizing down, a 50 mm bore gives 982 N push at 0.5 MPa; sizing up, an 80 mm bore provides 2513 N. Note that a plain cylinder drifts on air loss—the 21 mm cushions only decelerate the piston, so add an external rod lock or pilot-operated check valve for load holding. Finally, at 600 mm of travel, prevent rod bending by guiding the load externally to avoid side-load damage.
Replacement checklist
- ✓ Same bore / stroke → SAU63X600
- ✓ 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 SU63X600 FAQ
Yes, the AirTAC SU63X600 is discontinued and end-of-life. The direct replacement is the SAU63X600. It shares the identical 63 mm bore, 600 mm stroke, 3/8" port, and SC-series mounting hardware, so it fits the same application directly.
At 0.5 MPa it provides 1559 N push and 1402 N pull; at 0.7 MPa it pushes 2182 N, and the theoretical max is 318 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot take a sensor. If you need sensing, the SAU replacement supports CMSG/DMSG/EMSG switches, replacing the legacy CS1-B/DS1-B sensors.
