This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X320S, 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 SU63X320S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X320S is a double-acting profile-type standard cylinder with a Ø63mm bore and 320mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X320S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X320S
The AirTAC SU63X320S is a discontinued double-acting profile-type cylinder with a 63mm bore and 320mm stroke. Delivering 1559 N push at 0.5 MPa, its extruded aluminum barrel is shorter than an ISO 15552 unit of the same size. AirTAC replaced it with the direct replacement SAU63X320S: identical bore, stroke, force, 3/8" port and SC-series mounting.
The SAU upgrade switches the -S magnet from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors, and adds a SAUF built-in-valve option the SU lacked. Note that a standard cylinder drifts without live air; use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X320S 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 SAU63X320S 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 SU63X320S Is Used
Package Diverting
Actuates routing gates on packaging lines, using the 1559 N push force to deflect heavy cartons at high throughput speeds.
Material Lowering
Lowers stacked components with a 79 kg vertical lift capacity, relying on adjustable end cushions to decelerate the 320mm travel smoothly.
Clamp Actuation
Drives medium-duty workholding clamps on machining fixtures, maintaining grip through the 63mm bore during automated milling cycles.
Replacing the Airtac SU63-100 Standard Cylinder SU63X320S with the SAU63X320S
To replace this SU63X320S, order the SAU63X320S. Verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB/TC). Because this SKU includes a magnet (-S), you must upgrade your legacy CS1-B/DS1-B switches to the SAU-compatible CMSG/DMSG/EMSG family. If sizing neighbors, a 50mm bore yields 982 N push while an 80mm bore yields 2513 N at 0.5 MPa. The 320mm stroke warrants an external guide to prevent rod bending under side loads. For load holding on air loss, add a pilot-operated check valve or rod lock, as cushions only decelerate. The SAUF variant offers a built-in 4M valve if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU63X320S
- ✓ 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 SU63X320S FAQ
Yes, the SU63X320S is discontinued. The direct replacement is the AirTAC SAU63X320S. It shares the identical 63mm bore, 320mm stroke, output force, 3/8" port, and SC-series mounting, so it fits the same application. You simply order the SAU63X320S.
At 0.5 MPa it provides 1559 N push and 1402 N pull; 2182 N push at 0.7 MPa; 2805 N at 0.9 MPa; with a theoretical max of 318 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
