This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X400SN, 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 SU100X400SN
The AirTAC SU63-100 Standard Cylinder SU100X400SN is a double-acting profile-type standard cylinder with a Ø100mm bore and 400mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X400SN, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X400SN
The AirTAC SU100X400SN is a discontinued double-acting profile cylinder with a 100mm bore and 400mm stroke. AirTAC replaced this legacy unit with the SAU100X400SN, a direct alternative retaining the exact 1/2" port, M20x1.5 rod thread, and SC-series mounting footprint.
Because this SKU includes the -S magnet and -N NBR seal, it originally used legacy CS1-B/DS1-B switches and operates from -20 to +70 C. The SAU replacement upgrades sensing to CMSG/DMSG/EMSG switches while preserving the compact extruded aluminum body. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X400SN carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X400SN 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 SU100X400SN Is Used
Heavy Press Ejection
Provides the 3927 N push force needed to eject dense stamped parts from a hydraulic press bed over a 400mm travel distance.
Pallet Stopper Gate
Acts as a high-force stop gate on a heavy-duty roller conveyor, securely halting loaded pallets up to 200 kg in vertical lift scenarios.
Replacing the Airtac SU63-100 Standard Cylinder SU100X400SN with the SAU100X400SN
To replace the SU100X400SN, order the SAU100X400SN with the identical 100mm bore, 400mm stroke, 1/2" port, and SC-series mounting hardware. Confirm your thread standard (PT, G, or NPT) during ordering. Since your model has the -S magnet, note that legacy CS1-B/DS1-B switches are obsolete; you must upgrade to CMSG/DMSG/EMSG sensors for the SAU body. If you need integrated air control, explore the SAUF variant featuring a built-in 4M solenoid valve. For sizing alternatives, dropping to an 80mm bore reduces push force to 2513 N at 0.5 MPa, while maintaining 100mm gives 5497 N at 0.7 MPa. At 400mm stroke, prevent rod bending by supporting the load with an external guide. Finally, a plain cylinder drifts on air loss—the cushion only decelerates—so install an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAU100X400SN
- ✓ 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 SU100X400SN FAQ
Yes, the SU100X400SN is discontinued. The direct replacement is the SAU100X400SN. It preserves the 100mm bore, 400mm stroke, 1/2" port, 801 kgf max force, and SC-series mounting compatibility, fitting the same application space.
At 0.5 MPa it pushes 3927 N and pulls 3681 N; at 0.7 MPa it pushes 5497 N, with a theoretical max of 801 kgf at 1.0 MPa. The -S magnet works with legacy CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
