This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X630S, 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 SU63X630S
The AirTAC SU63-100 Standard Cylinder SU63X630S is a double-acting profile-type standard cylinder with a Ø63mm bore and 630mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X630S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X630S
The AirTAC SU63X630S is a discontinued double-acting profile-type cylinder with a 63mm bore and 630mm stroke. Delivering 1559N push force at 0.5MPa, it uses a 3/8" port and M16x1.5 rod thread. AirTAC replaced this end-of-line unit with the SAU63X630S, a direct replacement retaining the exact bore, stroke, force, port, and SC-series mounting.
Because this SKU includes a magnet, it originally used legacy CS1-B/DS1-B switches, whereas the SAU successor upgrades to CMSG/DMSG/EMSG sensors. The SAU family also adds a SAUF built-in-valve option the SU never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X630S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X630S 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 SU63X630S Is Used
Long-Stroke Diversion
Pushes heavy packages across transfer lines with a 630mm reach, utilizing the 1559N thrust at 0.5MPa to overcome lateral friction.
Multi-Station Indexing
Shifts machining pallets between work cells, relying on adjustable end cushions to safely decelerate moving masses at stroke completion.
Replacing the Airtac SU63-100 Standard Cylinder SU63X630S with the SAU63X630S
To replace this discontinued SU63X630S, order the SAU63X630S, confirming the 3/8" port, M16x1.5 thread, and SC-series mounting. If moving down to a 50mm bore, output drops to 982N push at 0.5MPa; stepping up to 80mm yields 2513N. Note that the -S magnet means you must switch from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. A 630mm stroke demands external guides to prevent rod bending under side loads. Finally, the cushion only decelerates; use an external rod lock or pilot-operated check valve to hold loads safely, as standard air cylinders drift without live air pressure.
Replacement checklist
- ✓ Same bore / stroke → SAU63X630S
- ✓ 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 SU63X630S FAQ
Yes, the SU63X630S is discontinued. The direct replacement is the AirTAC SAU63X630S. It shares the identical 63mm bore, 630mm stroke, 1559N output force at 0.5MPa, 3/8" port, and SC-series mounting accessories, so it bolts right in.
The 63mm bore delivers 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a 318kgf maximum at 1.0MPa. Because this is an -S magnet model, the original legacy CS1-B/DS1-B switches are obsolete; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
