This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X90S, 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 SU100X90S
The AirTAC Airtac SU63-100 Standard Cylinder SU100X90S is a double-acting profile-type standard cylinder with a Ø100mm bore and 90mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X90S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X90S
The AirTAC SU100X90S is a discontinued double-acting profile-type cylinder with a 100mm bore and 90mm stroke. Delivering 3927 N push force at 0.5 MPa, its direct replacement is the SAU100X90S, which preserves the 1/2" port, M20x1.5 rod thread, and SC-series mounting.
Because the -S suffix denotes a magnet, this legacy unit relied on CS1-B/DS1-B switches; upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU also introduces the SAUF built-in-valve variant, an option the original SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X90S 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 SAU100X90S 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 SU100X90S Is Used
Heavy Press Clamping
Ideal for securing heavy metal components during machining, utilizing the 3927 N push force at 0.5 MPa to hold parts firmly against cutting loads.
Large Mold Ejection
Drives the ejection of bulky molds from injection machinery, where the 100mm bore and adjustable 29mm cushions ensure smooth part removal.
Replacing the Airtac SU63-100 Standard Cylinder SU100X90S with the SAU100X90S
To replace this discontinued SU100X90S, order the SAU100X90S direct equivalent, verifying the 100mm bore, 90mm stroke, 1/2" port, and PT/G/NPT thread choice. Retain your SC-series mounting brackets, but note the -S magnet now requires CMSG/DMSG/EMSG switches instead of the old CS1-B/DS1-B. If you need higher force, the 100mm bore provides 3927 N push at 0.5 MPa, while a smaller 80mm bore yields 2513 N. For load holding, remember a standard cylinder drifts without live air—the 29mm cushions only decelerate—so add an external rod lock or pilot-operated check valve for safety.
Replacement checklist
- ✓ Same bore / stroke → SAU100X90S
- ✓ 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 SU100X90S FAQ
Yes, the SU100X90S is discontinued. The direct replacement is the AirTAC SAU100X90S. It matches the 100mm bore, 90mm stroke, 1/2" port, output force, and SC-series mounting, but uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 1/2" port feeds a bore that generates 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. The 29mm adjustable cushions only decelerate the load near stroke end; they do not hold the load without live air.
