This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X35S, 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 SU100X35S
The AirTAC Airtac SU63-100 Standard Cylinder SU100X35S is a double-acting profile-type standard cylinder with a Ø100mm bore and 35mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X35S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X35S
The AirTAC SU100X35S is a discontinued double-acting profile-type cylinder with a 100mm bore and 35mm stroke. Delivering 3927N push force at 0.5MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same bore. AirTAC replaced this with the SAU100X35S, a direct upgrade retaining the exact 1/2 inch port, M20x1.5 rod thread, and SC-series mounting.
Because this is an -S magnet model, it used legacy CS1-B/DS1-B switches; the SAU replacement upgrades to CMSG/DMSG/EMSG sensors. The SAU line also introduces the SAUF valve-integrated variant, an option the SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X35S 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 SAU100X35S 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 SU100X35S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×35 | 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 SU100X35S Is Used
Heavy Press Clamping
Secures large metal castings in machining fixtures, using the 3927N push force at 0.5MPa to prevent deflection during aggressive milling operations.
Stamping Ejection
Ejects heavy formed parts from hydraulic presses, where the compact profile body fits tight press crowns and the 35mm short stroke delivers rapid ejection.
Replacing the Airtac SU63-100 Standard Cylinder SU100X35S with the SAU100X35S
To replace the SU100X35S, order the SAU100X35S direct equivalent, verifying your 1/2 inch port thread (PT, G, or NPT) and SC-series mounting hardware. If moving down a bore size, the 80mm provides 2513N push at 0.5MPa; stepping up is not available as 100mm is the largest profile. The -S suffix means you must account for the sensor family change from CS1-B/DS1-B to CMSG/DMSG/EMSG. A plain cylinder drifts without live air, as the 29mm adjustable cushion only decelerates; use an external rod lock for holding. For high-cycle automation, consider the SAUF variant with its built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU100X35S
- ✓ 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 SU100X35S FAQ
Yes, the SU100X35S is discontinued. The direct replacement is the SAU100X35S, which shares the identical 100mm bore, 35mm stroke, 1/2 inch port, output force, and SC-series mounting. You can swap it directly without altering your mechanical setup.
The 100mm bore yields 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, and a theoretical max of 801kgf at 1.0MPa. Because this is an -S model, it used legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
