This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X325S, 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 SU100X325S
The AirTAC SU63-100 Standard Cylinder SU100X325S is a double-acting profile-type standard cylinder with a Ø100mm bore and 325mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X325S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X325S
The AirTAC SU100X325S is a discontinued double-acting profile-type cylinder with a 100mm bore and 325mm stroke. Delivering 3927 N push force at 0.5 MPa, it features an extruded aluminum barrel and adjustable air cushions. AirTAC replaced this EOL unit with the SAU100X325S, a direct replacement retaining the exact bore, stroke, 1/2" port, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches used on this -S model, and adds a SAUF built-in-valve option the SU line lacked. Note that plain cylinders drift on air loss; use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X325S 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 SAU100X325S 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.
Where the Airtac SU63-100 Standard Cylinder SU100X325S Is Used
Heavy Press Operations
Drives large stamping or forming presses requiring substantial thrust, utilizing the 3927 N push force at 0.5 MPa to deform heavy materials reliably.
Large Component Machining
Actuates heavy clamping fixtures on CNC machining centers for large block components, ensuring rigid holding without relying on air pressure for static retention.
Replacing the Airtac SU63-100 Standard Cylinder SU100X325S with the SAU100X325S
To replace the SU100X325S, order the SAU100X325S direct equivalent, verifying the 100mm bore, 325mm stroke, 1/2" port, M20x1.5 rod thread, and SC-series mounting. Because this is a -S magnet model, you must switch from the old CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family. If you need integrated flow control, explore the SAUF variant with its built-in 4M solenoid valve. For forces, the 100mm bore yields 3927 N push at 0.5 MPa; dropping to an 80mm bore gives 2513 N. The 325mm stroke requires external guides to prevent rod bending under side loads. Finally, remember the air cushion only decelerates; it does not hold the load—add a pilot-operated check valve for static positioning.
Replacement checklist
- ✓ Same bore / stroke → SAU100X325S
- ✓ 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 SU100X325S FAQ
Yes, the AirTAC SU100X325S is discontinued. The direct replacement is the SAU100X325S. It shares the identical 100mm bore, 325mm stroke, 1/2" port, output force, and SC-series mounting, but requires upgrading your sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG family.
The 100mm bore cylinder features a 1/2" port and a 25mm piston rod. It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa. Operating speed ranges from 30-800 mm/s.
