This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X380S, 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 SU63X380S
The AirTAC SU63-100 Standard Cylinder SU63X380S is a double-acting profile-type standard cylinder with a Ø63mm bore and 380mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X380S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X380S
The AirTAC SU63X380S is a discontinued double-acting profile-type cylinder with a 63mm bore and 380mm stroke. It delivered 1559N push and 1402N pull at 0.5MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X380S, a direct upgrade retaining the exact body, force, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches on this -S model, and adds a SAUF valve-integrated option. Because the 380mm stroke invites rod bending, use external guides to prevent side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X380S 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 SAU63X380S 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 SU63X380S
| SU | Profile-type standard cylinder (discontinued). |

| 63 | Bore size in mm. |
| ×380 | 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 SU63X380S Is Used
Vertical Lift Gate
Raises loading bay gates through the 380mm stroke, requiring external linear guides to prevent rod bending during the extended vertical travel.
Clamp Actuation
Secures heavy machined parts for milling, delivering 2182N clamping force at 0.7MPa while fitting into compact machinery footprints.
Replacing the Airtac SU63-100 Standard Cylinder SU63X380S with the SAU63X380S
To replace the SU63X380S, order the SAU63X380S. Verify your 3/8" port, M16x1.5 rod thread, and SC-series mounts (LB/FA/FB/CA/CB) carry over directly. If downsizing, a 50mm bore yields 982N push at 0.5MPa; if upsizing, an 80mm bore provides 2513N. The -S magnet means your old CS1-B/DS1-B switches are incompatible with the SAU groove—you must migrate to CMSG/DMSG/EMSG sensors. For the 380mm stroke, support the load with external guides to avoid rod bending. Note that air cushions only decelerate; they do not hold load on air loss, so fit an external rod lock or pilot-operated check valve if needed. The SAUF variant offers a built-in valve if you want self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU63X380S
- ✓ 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 SU63X380S FAQ
Yes, the SU63X380S is discontinued. The direct replacement is the AirTAC SAU63X380S. It shares the identical 63mm bore, 380mm stroke, 3/8" port, output force, and SC-series mounting, so it bolts right in. The SAU also adds the option of a SAUF built-in valve variant the SU lacked.
The cylinder provides 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a theoretical max of 318kgf at 1.0MPa. Because your SU has the -S magnet, note that the SAU replacement requires upgrading from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family.
