This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X420S, 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 SU100X420S
The AirTAC SU63-100 Standard Cylinder SU100X420S is a double-acting profile-type standard cylinder with a Ø100mm bore and 420mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X420S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X420S
The AirTAC SU100X420S is a discontinued double-acting profile cylinder with a 100mm bore and 420mm stroke. Delivering 3927 N push force at 0.5 MPa, it features a 1/2" port and M20x1.5 rod thread. AirTAC replaced this end-of-life unit with the SAU100X420S—a direct replacement retaining the exact bore, stroke, force, port, and SC-series mounting.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used on this -S model, and adds the SAUF built-in-valve option. The 29 mm adjustable cushions only decelerate; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X420S 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 SAU100X420S 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 SU100X420S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×420 | 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 SU100X420S Is Used
Heavy Press Ejection
Provides the 3927 N push at 0.5 MPa needed to eject dense metal stampings from a hydraulic press bed over the 420mm travel.
Mold Clamping Arm
Secures large injection molds via SC-series mounts, using its 801 kgf maximum theoretical force to lock heavy tooling halves in place.
Replacing the Airtac SU63-100 Standard Cylinder SU100X420S with the SAU100X420S
To replace this SU100X420S, order the SAU100X420S direct equivalent, verifying your 1/2" port, M20x1.5 thread, and SC-series mounting. Because the -S magnet is present, note the mandatory sensor family change: legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG on the SAU. If downsizing, a 80mm bore yields 2513 N push at 0.5 MPa; if upsizing is impossible, this 100mm bore hits 7068 N at 0.9 MPa. The 420mm stroke requires external guides to prevent rod bending under side loads. For load holding during air loss, add a pilot-operated check valve, as standard cushions only decelerate.
Replacement checklist
- ✓ Same bore / stroke → SAU100X420S
- ✓ 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 SU100X420S FAQ
Yes, the AirTAC SU100X420S is discontinued. The direct replacement is the SAU100X420S. It shares the identical 100mm bore, 420mm stroke, 1/2" port, output force, and SC-series mounting, but the SAU uses modern CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
This double-acting cylinder has a 1/2" port and generates 3927 N push / 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a maximum theoretical force of 801 kgf at 1.0 MPa.
