This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X350STC, 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 SU63X350STC
The AirTAC SU63-100 Standard Cylinder SU63X350STC is a double-acting profile-type standard cylinder with a Ø63mm bore and 350mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X350STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X350STC
The AirTAC SU63X350STC is a discontinued double-acting profile-type cylinder with a 63mm bore and 350mm stroke. It delivers 1559N push force at 0.5MPa through a 3/8" port. AirTAC replaced this legacy unit with the SAU63X350STC, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series TC mounting interface.
The SAU upgrade modernizes the sensor groove: your original -S magnet worked with legacy CS1-B/DS1-B switches, but the SAU replacement requires current CMSG/DMSG/EMSG sensors. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X350STC 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 SAU63X350STC 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 SU63X350STC Is Used
Package Diversion
Uses the 1559N push force at 0.5MPa to deflect heavy cartons on a sorting line, with the 350mm stroke clearing the adjacent lane.
Pallet Stopping
Deploys the TC mount to arrest inbound pallets at a packaging station, absorbing kinetic energy via the 21mm adjustable air cushions.
Replacing the Airtac SU63-100 Standard Cylinder SU63X350STC with the SAU63X350STC
To replace this SU63X350STC, order the SAU63X350STC. Confirm the 3/8" port, M16x1.5 rod thread, and TC mounting accessory are retained. Because this SKU includes the -S magnet, you must switch your legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors on the new cylinder. If you need integrated flow control, explore the SAUF valve-integrated variant. For sizing both ways, dropping to a 50mm bore yields 982N push at 0.5MPa, while stepping up to an 80mm bore provides 2513N. Note that a plain cylinder drifts on air loss—the cushion only decelerates, so add an external rod lock for held loads. Finally, at 350mm stroke, prevent rod bending by supporting the load against side-load forces with an external guide.
Replacement checklist
- ✓ Same bore / stroke → SAU63X350STC
- ✓ 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 SU63X350STC FAQ
Yes, the SU63X350STC is discontinued. The direct replacement is the AirTAC SAU63X350STC. It shares the identical 63mm bore, 350mm stroke, 3/8" port, output force, and SC-series TC mounting, so it drops directly into your existing setup.
The 63mm bore provides 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a 318kgf maximum at 1.0MPa. Because your model has the -S magnet, note that the legacy CS1-B/DS1-B switches are incompatible with the SAU replacement; you must upgrade to CMSG/DMSG/EMSG sensors.
