This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X500, 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 SU63X500
The AirTAC Airtac SU63-100 Standard Cylinder SU63X500 is a double-acting profile-type standard cylinder with a Ø63mm bore and 500mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X500, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X500
The AirTAC SU63X500 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 500 mm stroke. AirTAC replaced this unit with the SAU63X500, a direct upgrade retaining the exact 3/8" port, M16x1.5 rod thread, output force, and SC-series mounting footprint.
Because this SKU lacks a magnet, it cannot accept position sensors. If sensing is needed, the SAU replacement uses modern CMSG/DMSG/EMSG switches (the SU line relied on legacy CS1-B/DS1-B parts). The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, a self-switching feature the original never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X500 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 SAU63X500 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 SU63X500 Is Used
Long-Stroke Diversion
Pushes heavy pallets sideways off a main conveyor line using the full 500 mm travel and 1559 N thrust at 0.5 MPa.
Multi-Station Indexing
Shifts a machining fixture between tooling stations over a 500 mm span, relying on external guides to prevent rod bending.
Replacing the Airtac SU63-100 Standard Cylinder SU63X500 with the SAU63X500
To replace the SU63X500, order the SAU63X500. Verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware (LB/FA/FB/CA/CB) — all remain identical. Since this specific SKU has no magnet (-S), it cannot support a sensor; if your application requires end-of-stroke detection, specify an SAU63X500S and migrate to CMSG/DMSG/EMSG switches. For sizing, a 50 mm bore provides 982 N push at 0.5 MPa (too small), while an 80 mm bore offers 2513 N. At 500 mm stroke, prevent rod bending and premature seal wear by guiding the load externally to avoid side-loading. Note that a standard cylinder drifts on air loss; for load holding, install an external rod lock or pilot-operated check valve, as the adjustable 21 mm cushions only decelerate near stroke end.
Replacement checklist
- ✓ Same bore / stroke → SAU63X500
- ✓ 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 SU63X500 FAQ
Yes, the SU63X500 is end-of-life. The direct replacement is the AirTAC SAU63X500. It matches the 63 mm bore, 500 mm stroke, 3/8" port, M16x1.5 thread, force output, and SC-series mounting accessories, so it fits the same application without mechanical changes.
At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa it pushes 2182 N, with a theoretical max of 318 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot take a sensor. If you need position detection, the SAU replacement requires CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B.
