This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X320, 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 SU100X320
The AirTAC Airtac SU63-100 Standard Cylinder SU100X320 is a double-acting profile-type standard cylinder with a Ø100mm bore and 320mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X320, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X320
The AirTAC SU100X320 is a discontinued double-acting profile-type cylinder with a 100 mm bore and 320 mm stroke. It delivers 3927 N push force at 0.5 MPa and features a 1/2 inch air port. AirTAC replaced this EOL unit with the SAU100X320, a direct alternative retaining the exact bore, stroke, output force, port size and SC-series mounting.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a SAUF built-in 4M solenoid valve option the SU line lacked. Note this non-magnetic SKU cannot accept a sensor, and the air cushion only decelerates; it will not hold a load without an external rod lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X320 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 SAU100X320 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 SU100X320 Is Used
Heavy Stamping Press
Drives heavy-duty stamping and forming dies requiring high thrust, utilizing the 3927 N push force at 0.5 MPa to shape thick metal components.
Bulk Material Diversion
Actuates large routing gates on heavy-duty conveyor lines, relying on the robust 25 mm piston rod to deflect dense bulk materials.
Replacing the Airtac SU63-100 Standard Cylinder SU100X320 with the SAU100X320
To replace the SU100X320, order the SAU100X320. Verify your 1/2 inch port thread (PT, G or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB) which carry over directly. Because this is a non-magnetic SKU, it cannot accept a sensor; if detection is needed, specify an SAU100X320S and migrate to CMSG/DMSG/EMSG switches. Sizing both ways: dropping to an 80 mm bore yields 2513 N push at 0.5 MPa, while a 100 mm bore at 0.7 MPa provides 5497 N. For the 320 mm stroke, use external guides to prevent rod bending under side loads. Remember the cushion only decelerates; use a pilot-operated check valve for load holding. Consider the SAUF variant if you need a built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU100X320
- ✓ 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 SU100X320 FAQ
Yes, the SU100X320 is discontinued. The direct replacement is the AirTAC SAU100X320. It matches the 100 mm bore, 320 mm stroke, 1/2 inch port, force output, and SC-series mounting accessories perfectly.
It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot accept a sensor. The SAU replacement with a magnet (-S) uses CMSG/DMSG/EMSG switches.
