This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X355S, 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 SU100X355S
The AirTAC Airtac SU63-100 Standard Cylinder SU100X355S is a double-acting profile-type standard cylinder with a Ø100mm bore and 355mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X355S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X355S
The AirTAC SU100X355S is a discontinued double-acting profile-type cylinder featuring a 100mm bore, 355mm stroke, and a 1/2 inch air port. Delivering 3927 N of push force at 0.5 MPa, this extruded aluminum unit is more compact than an ISO 15552 cylinder of the same bore and shares AirTAC SC-series mounting accessories.
The direct replacement is the SAU100X355S, matching the bore, stroke, output force, port size, and mounts. Because this SKU includes a magnet (-S), note that its legacy CS1-B/DS1-B switches are upgraded to CMSG/DMSG/EMSG sensors on the SAU, which also introduces the SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X355S 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 SAU100X355S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×355 | Stroke length in mm. |
| -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.
Where the Airtac SU63-100 Standard Cylinder SU100X355S Is Used
Heavy Press Clamping
Secures large metal castings in machining fixtures, utilizing the 3927 N push force at 0.5 MPa to hold components rigidly against cutting forces.
Bulk Material Diversion
Drives large profile diverters on high-throughput packaging lines, where the 355mm stroke provides the reach needed to redirect heavy goods.
Replacing the Airtac SU63-100 Standard Cylinder SU100X355S with the SAU100X355S
To replace this discontinued SU100X355S, order the SAU100X355S direct equivalent, verifying your 1/2 inch port threads (PT/G/NPT) and SC-series mounting hardware. The -S magnet means you must migrate from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For sizing alternatives, a neighboring 80mm bore yields 2513 N push at 0.5 MPa, while the 100mm bore hits 5497 N at 0.7 MPa. A plain cylinder drifts without live air—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for held loads. With the 355mm stroke, use external guides to prevent rod bending under side loads. Consider the SAUF variant if you need a built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU100X355S
- ✓ 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 SU100X355S FAQ
Yes, the SU100X355S is discontinued. The direct replacement is the SAU100X355S, which matches the 100mm bore, 355mm stroke, 1/2 inch port, output force, and SC-series mounting. You simply order the SAU equivalent.
The bore delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a maximum theoretical force of 801 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAU upgrade.
