This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X100S, 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 SU100X100S
The AirTAC Airtac SU63-100 Standard Cylinder SU100X100S is a double-acting profile-type standard cylinder with a Ø100mm bore and 100mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X100S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X100S
The AirTAC SU100X100S is a discontinued double-acting profile-type cylinder featuring a 100mm bore and 100mm stroke. It delivers 3927 N push force at 0.5 MPa and includes a piston magnet for position sensing. AirTAC replaced this unit with the SAU100X100S, a direct replacement retaining the exact 1/2" port, M20x1.5 rod thread, and SC-series mounting compatibility.
This SAU upgrade keeps the compact extruded aluminum body but modernizes the sensor groove. Your original CS1-B/DS1-B switches are obsolete; the SAU requires CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X100S 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 SAU100X100S 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 SU100X100S

| 100 | Bore size in mm. |
| ×100 | 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 SU100X100S Is Used
Heavy Stamping Press
Drives heavy-duty stamping and forming dies requiring high thrust, utilizing the 7068 N push force at 0.7 MPa to shape thick metal blanks reliably.
Pallet Lift Station
Lifts loaded pallets vertically in distribution hubs, safely moving loads up to 200 kg while benefiting from the 29mm adjustable end cushions to prevent shock.
Automated Clamping Cell
Secures large automotive components during machining operations, taking advantage of the compact extruded profile to save floor space in tight cells.
Replacing the Airtac SU63-100 Standard Cylinder SU100X100S with the SAU100X100S
To replace the SU100X100S, order the SAU100X100S direct equivalent, verifying your 1/2" port thread (PT, G, or NPT) and SC-series mounting brackets (LB, FA, FB, CA, CB, TC). Because this SKU includes the -S magnet, prepare to upgrade your legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. If sizing alternatives, the neighboring 80mm bore yields 2513 N push at 0.5 MPa, while stepping up is unnecessary given this bore's 801 kgf maximum at 1.0 MPa. For any stroke length over 300mm, add external guide rails to prevent rod bending under side loads. Remember that neither the SU nor SAU holds load without live air; the cushions only decelerate, so install an external rod lock or pilot-operated check valve for fail-safe holding.
Replacement checklist
- ✓ Same bore / stroke → SAU100X100S
- ✓ 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 SU100X100S FAQ
Yes, the SU100X100S is discontinued. The direct replacement is the AirTAC SAU100X100S. It shares the identical 100mm bore, 100mm stroke, 1/2" port, output force, and SC-series mounting hardware, allowing a direct physical swap without machine modifications.
The cylinder provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa. Because your SU model has the -S magnet, note that the SAU replacement changes the sensor family: legacy CS1-B/DS1-B switches are replaced by current CMSG/DMSG/EMSG switches.
