This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X350STC, 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.

The AirTAC SU63-100 Standard Cylinder SU100X350STC is a double-acting profile-type standard cylinder with a Ø100mm bore and 350mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X350STC, which matches its bore, stroke, force and mounting.
The AirTAC SU100X350STC is a discontinued double-acting profile-type cylinder featuring a 100mm bore, 350mm stroke, and an extruded aluminum barrel. It delivers 3927 N push force at 0.5 MPa and uses a 1/2" port. AirTAC replaced this end-of-life unit with the SAU100X350STC, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
The SAU replacement introduces current CMSG/DMSG/EMSG sensors, superseding the legacy CS1-B/DS1-B switches used on this SU -S model, and adds an optional SAUF built-in-valve variant. Note that a plain cylinder drifts without live air; the 29mm adjustable cushions only decelerate near stroke ends, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X350STC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X350STC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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.
Provides the robust 3927 N push force required to eject dense stamped metal components from a hydraulic press bed.
Acts as a high-force stop gate in conveyor systems, securely halting fully loaded 1000kg pallets before a wrapping station.
Drives heavy-duty clamping arms to secure large injection molds, utilizing the TC mount to handle substantial off-center loads.
To replace the SU100X350STC, order the SAU100X350STC, confirming the 100mm bore, 350mm stroke, 1/2" port, M20x1.5 rod thread, and TC mounting. Because the -S magnet is present, prepare to upgrade from CS1-B/DS1-B switches to the SAU's CMSG/DMSG/EMSG sensor family. If you need higher force, the next standard bore up offers 5497 N push at 0.7 MPa; if lowering pressure is desired, this 100mm bore still yields 3927 N at 0.5 MPa. With a 350mm stroke, prevent rod bending by supporting the load against side-load forces with an external guide. For load holding on air loss, add a pilot-operated check valve or rod lock, as cushions only decelerate. The SAUF variant adds a built-in 4M solenoid valve if integrated switching is needed.
Replacement checklist
Yes, the AirTAC SU100X350STC is discontinued. The direct replacement is the SAU100X350STC. It matches the original 100mm bore, 350mm stroke, 1/2" port, force, and SC-series TC mounting, so no mechanical redesign is needed.
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. Because this is an -S model with a piston magnet, the original CS1-B/DS1-B switches must be replaced by CMSG/DMSG/EMSG sensors on the new SAU unit.
