This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X590S, 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 SU100X590S
The AirTAC SU63-100 Standard Cylinder SU100X590S is a double-acting profile-type standard cylinder with a Ø100mm bore and 590mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X590S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X590S
The AirTAC SU100X590S is a discontinued double-acting profile-type cylinder with a 100mm bore and 590mm stroke. It delivers 3927 N push force at 0.5 MPa and features a 1/2 inch port. AirTAC replaced this end-of-line unit with the SAU100X590S, a direct replacement retaining the exact same body dimensions, output force, and SC-series mounting compatibility.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used on this SU -S model, and offers a new SAUF built-in-valve variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X590S 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 SAU100X590S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×590 | 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 SU100X590S Is Used
Heavy Material Transfer
Drives robust pallet stops and heavy-gauge workpiece diverters on high-capacity conveyor lines using its 3927 N push force.
Press Ejection
Ejects dense molded or stamped components from heavy machinery, relying on adjustable 29mm end cushions to absorb impact.
Replacing the Airtac SU63-100 Standard Cylinder SU100X590S with the SAU100X590S
To replace the SU100X590S, order the SAU100X590S direct equivalent. Verify your 1/2 inch port thread (PT, G, or NPT) and SC-series mounting hardware (LB, FA, FB, CA, CB, TC). Because this unit has a -S magnet, you must upgrade your switches: legacy CS1-B/DS1-B sensors will not fit the SAU, requiring current CMSG/DMSG/EMSG equivalents. If you need higher force, step up to a larger bore; if less, step down. Note that a plain cylinder does not hold load on air loss—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for holding. Given the 590mm stroke, use an external guide to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same bore / stroke → SAU100X590S
- ✓ 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 SU100X590S FAQ
Yes, the SU100X590S is discontinued. The direct replacement is the SAU100X590S. It matches the 100mm bore, 590mm stroke, 1/2 inch port, output force, and SC-series mounting. You can swap it directly without altering your mechanical setup.
At 0.5 MPa it provides 3927 N push and 3681 N pull force; 5497 N push at 0.7 MPa; 7068 N at 0.9 MPa; with a theoretical max of 801 kgf at 1.0 MPa. Because this is a -S model with a magnet, it used legacy CS1-B/DS1-B switches. The SAU replacement requires upgrading to current CMSG/DMSG/EMSG sensors.
