This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X265S, 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 SU100X265S
The AirTAC SU63-100 Standard Cylinder SU100X265S is a double-acting profile-type standard cylinder with a Ø100mm bore and 265mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X265S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X265S
The AirTAC SU100X265S is a discontinued double-acting profile-type cylinder with a 100mm bore and 265mm stroke, delivering 3927N push and 3681N pull at 0.5 MPa. Its extruded aluminum barrel is shorter than an ISO 15552 unit of the same size. AirTAC replaced this EOL unit with the SAU100X265S, a direct replacement retaining the exact 1/2" port, M20x1.5 rod thread, and SC-series mounting.
Upgrading to the SAU100X265S keeps the body and force identical, but the legacy CS1-B/DS1-B switches on this -S magnet model must change to current CMSG/DMSG/EMSG sensors. The SAU line also adds a SAUF valve-integrated option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X265S 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 SAU100X265S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SU63-100 Standard Cylinder SU100X265S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×265 | 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 SU100X265S Is Used
Heavy Press Clamping
Secures large metal castings during machining operations, utilizing the 3927N push force at 0.5 MPa to prevent workpiece shifting under cutting loads.
Replacing the Airtac SU63-100 Standard Cylinder SU100X265S with the SAU100X265S
To replace the SU100X265S, order the SAU100X265S direct equivalent, verifying your 1/2" port, M20x1.5 rod thread, and SC-series mounting hardware. Because this SKU has the -S magnet, note the sensor family changes from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. Sizing both ways: dropping to an 80mm bore gives 2513N [email protected], while staying at 100mm yields 5497N [email protected]. A plain cylinder drifts without live air, so use an external rod lock for held loads. At 265mm stroke, use guide rails to prevent rod bending from side loads. The SAUF variant offers a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU100X265S
- ✓ 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 SU100X265S FAQ
Yes, the SU100X265S is discontinued. The direct replacement is the AirTAC SAU100X265S, which shares the same 100mm bore, 265mm stroke, 3927N force, 1/2" port, and SC-series mounting.
At 0.5 MPa it pushes 3927N and pulls 3681N; at 0.7 MPa it pushes 5497N, with a theoretical max of 801 kgf at 1.0 MPa. This -S model used legacy CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
