This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X650, 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 SU100X650
The AirTAC Airtac SU63-100 Standard Cylinder SU100X650 is a double-acting profile-type standard cylinder with a Ø100mm bore and 650mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X650, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X650
The AirTAC SU100X650 is a discontinued double-acting profile-type cylinder featuring a 100 mm bore and 650 mm stroke. Built with an extruded aluminum barrel, it is shorter and more compact than an ISO 15552 cylinder of the same bore, delivering 3927 N of push force at 0.5 MPa. The direct replacement is the SAU100X650, matching the bore, stroke, 1/2" port, output force, and SC-series mounting.
This unit has no magnet (-S) and cannot accept a magnetic sensor. If sensing is needed on the SAU replacement, it uses current CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B type. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the original SU line lacked.

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 SAU100X650 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 SU100X650 Is Used
Heavy Stamp Press Feed
Drives robust 200 kg material blanks into a hydraulic press, utilizing the 3927 N push force at 0.5 MPa to overcome initial mechanical friction.
Pallet Discharge Gate
Actuates a 650 mm travel discharge door on a high-volume packaging line, moving heavy loaded pallets laterally with reliable 1/2" port airflow.
Mold Ejection System
Ejects dense composite molds from a curing oven, requiring the 7068 N thrust at 0.9 MPa to break the part free from the heated tooling surface.
Replacing the Airtac SU63-100 Standard Cylinder SU100X650 with the SAU100X650
To replace the discontinued SU100X650, order the SAU100X650 direct equivalent, verifying the 100 mm bore, 650 mm stroke, 1/2" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU lacks a magnet, it cannot take a sensor; if position detection is required on the new SAU, you must migrate to the CMSG/DMSG/EMSG switch family. When sizing, consider the neighboring 80 mm bore (2513 N push at 0.5 MPa) for lighter loads, or the 100 mm bore at 0.7 MPa (5497 N) for heavier demands. For the 650 mm stroke, use external guides to prevent rod bending and side-load damage. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock or pilot-operated check valve for held loads. The SAUF valve-integrated variant is available if self-switching is desired.
Replacement checklist
- ✓ Same bore / stroke → SAU100X650
- ✓ 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 SU100X650 FAQ
Yes, the AirTAC SU100X650 is discontinued and end-of-life. The direct replacement is the SAU100X650. It provides identical specifications: 100 mm bore, 650 mm stroke, 1/2" port, M20x1.5 rod thread, and SC-series mounting compatibility. You can install the SAU100X650 directly into the same application without modifying the fixture.
At 0.5 MPa it provides 3927 N push and 3681 N pull; at 0.7 MPa it pushes 5497 N, and 7068 N at 0.9 MPa. The theoretical maximum is 801 kgf at 1.0 MPa. This specific SKU has no magnet and cannot accept a sensor. If you need position detection on the SAU replacement, you must use the current CMSG/DMSG/EMSG switch family, as the older CS1-B/DS1-B switches are obsolete.
