This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X275S, 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 SU100X275S
The AirTAC SU63-100 Standard Cylinder SU100X275S is a double-acting profile-type standard cylinder with a Ø100mm bore and 275mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X275S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X275S
The AirTAC SU100X275S is a discontinued double-acting profile-type cylinder with a 100mm bore and 275mm stroke. Delivering 3927N push and 3681N pull at 0.5MPa, it uses an extruded aluminium barrel that is more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this end-of-life unit with the SAU100X275S, a direct replacement retaining the exact 1/2in port, M20x1.5 rod thread, 29mm cushions, output force and SC-series mounting.
When upgrading to the SAU100X275S, note that your legacy CS1-B/DS1-B switches must change to the current CMSG/DMSG/EMSG sensor family, as the magnet groove geometry evolved. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the original SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X275S 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 SAU100X275S 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. |
| ×275 | 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 SU100X275S Is Used
Heavy Press Clamping
Ideal for securing heavy metal components during machining, utilising the 3927N push force at 0.5MPa to hold parts firmly against the fixture bed.
Bulk Material Diversion
Actuates heavy-duty deflector gates on high-throughput conveyor lines, relying on the 29mm adjustable air cushions to decelerate the 275mm stroke smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU100X275S with the SAU100X275S
To replace the discontinued SU100X275S, order the SAU100X275S direct equivalent, verifying your 1/2in port, M20x1.5 rod thread, PT/G/NPT thread standard, and SC-series mounting hardware (LB/FA/FB/CA/CB). Because this SKU includes the -S magnet, you must upgrade your position sensors from the old CS1-B/DS1-B reed switches to the modern CMSG/DMSG/EMSG electronic family. If your application requires integrated flow control, explore the SAUF variant which features a built-in 4M valve. For loads requiring 7068N push at 0.9MPa, this 100mm bore is ideal, but if you need less force, consider the 80mm bore (2513N push at 0.5MPa). Remember, a standard cylinder does not hold load without live air; the 29mm adjustable cushions only decelerate near stroke end, so add an external rod lock or pilot-operated check valve for fail-safe holding. With a 275mm stroke, ensure adequate guidance to prevent rod bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU100X275S
- ✓ 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 SU100X275S FAQ
Yes, the AirTAC SU100X275S is discontinued. The direct replacement is the SAU100X275S. It shares the identical 100mm bore, 275mm stroke, 1/2in port, force output, and SC-series mounting, so it fits the same application. You simply order the SAU100X275S as a direct replacement.
At 0.5MPa it provides 3927N push and 3681N pull, increasing to 5497N push at 0.7MPa, with a theoretical maximum of 801kgf at 1.0MPa. Because this is an -S magnet model, it originally used CS1-B/DS1-B switches. When upgrading to the SAU replacement, you must switch to the current CMSG/DMSG/EMSG sensor family.
