This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X400N, 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 SU63X400N
The AirTAC SU63-100 Standard Cylinder SU63X400N is a double-acting profile-type standard cylinder with a Ø63mm bore and 400mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X400N, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X400N
The AirTAC SU63X400N is a discontinued double-acting profile-type cylinder with a 63 mm bore and 400 mm stroke. It delivers 1559 N push force at 0.5 MPa via a 3/8 inch port. AirTAC replaced this end-of-line unit with the SAU63X400N, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting.
The SAU body uses current CMSG/DMSG/EMSG sensors, whereas this legacy SKU lacks a magnet and cannot accept any switch. The SAU line also adds a SAUF built-in 4M valve option the SU never had. The NBR seal handles -20 to +70 C.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X400N 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 SAU63X400N produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Pallet Lift Gates
Actuates 63 mm bore lifting gates using 3/8 inch ports, relying on external guides for the 400 mm extension.
Replacing the Airtac SU63-100 Standard Cylinder SU63X400N with the SAU63X400N
To replace this SU63X400N, order the SAU63X400N: it matches the 63 mm bore, 400 mm stroke, M16x1.5 rod thread, 3/8 inch port, and SC-series mounts. Because this SKU has no -S magnet, it cannot support sensing, but if you need sensors on the SAU, specify the -S option and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. If downsizing, a 50 mm bore gives 982 N push at 0.5 MPa; if upsizing, an 80 mm bore yields 2513 N. At 400 mm stroke, prevent rod bending by guiding the load externally. The cushion only decelerates the piston; for load holding on air loss, install an external rod lock or pilot-operated check valve. The SAUF valve-integrated variant can simplify cycling if you lack a separate solenoid.
Replacement checklist
- ✓ Same bore / stroke → SAU63X400N
- ✓ 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 SU63X400N FAQ
Yes, the SU63X400N is discontinued. The direct replacement is the AirTAC SAU63X400N, which shares the identical 63 mm bore, 400 mm stroke, force, 3/8 inch port, and SC-series mounting.
It delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N at 0.9 MPa, and a 318 kgf max at 1.0 MPa. This non-magnetic SKU cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
