This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X400STC, 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 SU63X400STC
The AirTAC SU63-100 Standard Cylinder SU63X400STC 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 SAU63X400STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X400STC
The AirTAC SU63X400STC is a discontinued double-acting profile-type cylinder with a 63mm bore and 400mm stroke. Delivering 1559 N push force at 0.5 MPa, it utilizes an extruded aluminum barrel with adjustable air cushions at both ends, making it more compact than an ISO 15552 cylinder of the same bore. The direct replacement is the SAU63X400STC, matching the bore, stroke, 3/8" port, output force, and SC-series TC mounting.
When upgrading to the SAU, the body and footprint remain identical, but the legacy CS1-B/DS1-B sensors used on this -S model are replaced by the current CMSG/DMSG/EMSG switch family. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve that the SU series lacked.

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 SAU63X400STC 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 SU63X400STC Is Used
Pallet Diversion
Handles 79 kg vertical lift loads on packaging lines, using the 400mm stroke to push heavy pallets onto parallel conveyors safely.
Press Ejection
Generates 1559 N of push force at 0.5 MPa to eject stamped metal parts from press dies, relying on adjustable cushions to stop smoothly.
Material Gate Control
Actuates large sorting gates in distribution centers, where the TC mount and 3/8" port provide stable flow for high-speed routing.
Replacing the Airtac SU63-100 Standard Cylinder SU63X400STC with the SAU63X400STC
To replace this discontinued SU63X400STC, order the SAU63X400STC. Verify the 3/8" port, M16x1.5 rod thread, and TC mounting accessory are retained. Because this SKU includes the -S magnet, note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. If you need self-switching, the SAU family offers the SAUF variant with a built-in valve. For neighboring bores, a 50mm bore provides 982 N push at 0.5 MPa, while an 80mm bore yields 2513 N. A plain cylinder drifts without live air, so for load holding use an external rod lock or pilot-operated check valve. At 400mm stroke, prevent rod bending by supporting the load against side-load forces with an external guide.
Replacement checklist
- ✓ Same bore / stroke → SAU63X400STC
- ✓ 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 SU63X400STC FAQ
Yes, the SU63X400STC is discontinued. The direct replacement is the SAU63X400STC. It offers the same 63mm bore, 400mm stroke, 3/8" port, output force, and SC-series TC mounting compatibility. You can install the SAU directly into your existing setup.
At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa it pushes 2182 N, with a theoretical max of 318 kgf at 1.0 MPa. Because this is an -S model, the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU upgrade.
