This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X650S, 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 SU100X650S
The AirTAC SU63-100 Standard Cylinder SU100X650S 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 SAU100X650S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X650S
The AirTAC SU100X650S is a discontinued double-acting profile-type cylinder with a 100mm bore and 650mm stroke. Delivering 3927 N push force at 0.5 MPa, it features a 1/2" port and an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this end-of-life unit with the SAU100X650S, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting.
The -S magnet on this legacy model worked with CS1-B/DS1-B switches, but the SAU replacement uses current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF built-in 4M solenoid valve option the SU never had. Note that a plain cylinder drifts without live air; the cushions only decelerate.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X650S 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 SAU100X650S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 100 | Bore size in mm. |
| ×650 | 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 SU100X650S Is Used
Press Ejection Systems
Ejects heavy formed parts from industrial presses, utilizing the 650mm stroke and adjustable 29mm cushions to decelerate loads smoothly.
Large Material Diversion
Diverts bulky items on high-capacity conveyor lines, where the 100mm bore provides the necessary thrust and the profile body saves space.
Replacing the Airtac SU63-100 Standard Cylinder SU100X650S with the SAU100X650S
To replace this discontinued SU100X650S, order the SAU100X650S direct equivalent, confirming the 100mm bore, 650mm stroke, 1/2" port, M20x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this -S model has a magnet, you must switch from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family. Sizing both ways: a neighboring 80mm bore yields 2513 N push at 0.5 MPa, while stepping up is unnecessary if 3927 N suffices. For the 650mm stroke, use an external guide to prevent rod bending under side loads. This cylinder does not hold load on air loss; use an external rod lock or pilot-operated check valve for secure holding. If you need integrated control, explore the SAUF variant with its built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU100X650S
- ✓ 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 SU100X650S FAQ
Yes, the SU100X650S is discontinued. The direct replacement is the AirTAC SAU100X650S. It matches the 100mm bore, 650mm stroke, 1/2" port, output force, 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. The -S magnet on this legacy model used CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
