This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X310S, 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 SU100X310S
The AirTAC SU63-100 Standard Cylinder SU100X310S is a double-acting profile-type standard cylinder with a Ø100mm bore and 310mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X310S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X310S
The AirTAC SU100X310S is a discontinued double-acting profile-type cylinder with a 100mm bore and 310mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 unit of the same bore and delivers 3927 N push force at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAU100X310S, a direct replacement retaining the exact bore, stroke, 1/2" port, M20x1.5 rod thread and SC-series mounting.
The -S magnet on this legacy model paired with CS1-B/DS1-B switches, whereas the SAU upgrade utilizes current CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF variant featuring a built-in 4M solenoid valve, an integrated self-switching option the SU series never offered.

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 SAU100X310S 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 SU100X310S Is Used
Heavy Pressing
Drives large stamping or forming presses requiring up to 5497 N of push force at 0.7 MPa, utilizing the 100mm bore for heavy industrial deformation tasks.
Bulk Diversion
Actuates heavy-duty diverter arms on high-capacity conveyor lines, using the 310mm stroke to clear wide product flows effectively.
Replacing the Airtac SU63-100 Standard Cylinder SU100X310S with the SAU100X310S
To replace the SU100X310S, order the SAU100X310S direct equivalent, verifying your thread type (PT/G/NPT) and SC-series mounting hardware (LB/FA/FB/CA/CB). Because this SKU includes the -S magnet, note that your legacy CS1-B/DS1-B switches must change to the CMSG/DMSG/EMSG family on the new SAU cylinder. When sizing, the 100mm bore yields 3927 N push and 3681 N pull at 0.5 MPa; if stepping down to an 80mm bore, expect a drop to 2513 N push. For load holding, a plain cylinder drifts on air loss since the 29mm adjustable cushions only decelerate near stroke end—install an external rod lock or pilot-operated check valve for secure positioning. At 310mm stroke, prevent rod bending by using an external guide to absorb side loads. If valve integration is desired, explore the SAUF variant.
Replacement checklist
- ✓ Same bore / stroke → SAU100X310S
- ✓ 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 SU100X310S FAQ
Yes, the AirTAC SU100X310S is discontinued. The direct replacement is the SAU100X310S, which matches the 100mm bore, 310mm stroke, 1/2" port, output force and SC-series mounting. You simply order the SAU equivalent.
At 0.5 MPa it provides 3927 N push and 3681 N pull; at 0.7 MPa push is 5497 N, with a theoretical max of 801 kgf at 1.0 MPa. The -S magnet on this unit works with legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
