This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X335S, 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 SU100X335S
The AirTAC SU63-100 Standard Cylinder SU100X335S is a double-acting profile-type standard cylinder with a Ø100mm bore and 335mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X335S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X335S
The AirTAC SU100X335S is a discontinued double-acting profile-type cylinder with a 100 mm bore and 335 mm stroke. It delivers 3927 N push force at 0.5 MPa and features a 1/2" port. AirTAC replaced this legacy unit with the SAU100X335S, a direct alternative retaining the exact same body dimensions, output force, port size, and SC-series mounting compatibility.
When upgrading to the SAU100X335S, your -S magnet equipped model will transition from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve, an option the original SU lacked.

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 SAU100X335S 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 SU100X335S Is Used
Heavy Stamping Press
Drives heavy stamping and forming dies requiring substantial push force, utilizing the 100 mm bore to deliver consistent impact over the 335 mm travel.
Pallet Diverting
Actuates large pallet routing gates and heavy diverters in high-throughput distribution centers, moving loads safely within its 200 kg vertical lift capacity.
Large Mold Ejection
Ejects substantial molded products or cast components from machinery, relying on the 29 mm adjustable end cushions to smoothly decelerate the 25 mm rod.
Replacing the Airtac SU63-100 Standard Cylinder SU100X335S with the SAU100X335S
To replace this SU100X335S, order the SAU100X335S and verify your 1/2" port thread (PT, G, or NPT) along with your SC-series mounting accessories, which remain fully compatible. Because this is a 335 mm stroke, you must support the load with external guides to prevent rod bending and premature seal wear from side loads. If your application requires a held load during air loss, note that the adjustable 29 mm air cushions only decelerate the piston at stroke ends; you must add an external rod lock or pilot-operated check valve, as a standard cylinder drifts without live air. For lower force needs, a 80 mm bore provides 2513 N push at 0.5 MPa, while staying at 100 mm bore offers 7068 N push at 0.9 MPa. If you want to simplify actuation, explore the SAUF built-in valve option.
Replacement checklist
- ✓ Same bore / stroke → SAU100X335S
- ✓ 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 SU100X335S FAQ
Yes, the SU100X335S is discontinued. The direct replacement is the AirTAC SAU100X335S. It matches the 100 mm bore, 335 mm stroke, 1/2" port, output force, and SC-series mounting accessories, so it fits the same application directly.
At 0.5 MPa it provides 3927 N push and 3681 N pull force, increasing to 5497 N push at 0.7 MPa, with a theoretical max of 801 kgf at 1.0 MPa. Because this is an -S magnet model, the original SU used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
