This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X90SFA, 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 SU100X90SFA
The AirTAC SU63-100 Standard Cylinder SU100X90SFA 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 SAU100X90SFA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X90SFA
The AirTAC SU100X90SFA is a discontinued double-acting profile-type cylinder with a 100mm bore and 90mm stroke. It delivers a robust 3927 N push force at 0.5 MPa, making it a heavy-duty choice for demanding pneumatic setups. AirTAC replaced this end-of-line unit with the SAU100X90SFA, a direct upgrade retaining the exact 1/2" port, M20x1.5 rod thread, and SC-series FA mounting interface.
This transition brings key upgrades: the SAU accepts modern CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used on this -S SKU, and introduces the SAUF built-in 4M valve option the SU line lacked. The extruded aluminum profile remains shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X90SFA 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 SAU100X90SFA 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 SU100X90SFA Is Used
Heavy-Duty Stamping
Drives large press tools and forming dies requiring up to 3927 N of push force at 0.5 MPa with stable FA foot mounting.
Automated Clamping
Secures large fabricated steel frames during welding or machining operations using its 90mm stroke and robust 801 kgf max force.
Replacing the Airtac SU63-100 Standard Cylinder SU100X90SFA with the SAU100X90SFA
To replace this SU100X90SFA, order the SAU100X90SFA, confirming the 100mm bore, 90mm stroke, 1/2" port, and FA foot mounting are retained for a direct. If downsizing, a neighboring 80mm bore yields 2513 N push at 0.5 MPa; if uprating to 0.7 MPa provides 5497 N. Because this SKU includes a magnet (-S), note that your legacy CS1-B/DS1-B switches must change to CMSG/DMSG/EMSG sensors on the SAU. A plain cylinder drifts without live air—the cushion only decelerates—so fit an external rod lock for held loads. The SAUF valve-integrated variant is worth exploring if you need self-switching. At 90mm stroke, side-load rod bending is minimal, but always guide the load.
Replacement checklist
- ✓ Same bore / stroke → SAU100X90SFA
- ✓ 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 SU100X90SFA FAQ
Yes, the SU100X90SFA is discontinued. The direct replacement is the SAU100X90SFA, which matches the 100mm bore, 90mm stroke, 1/2" port, output force, and SC-series FA mounting. You simply order the SAU equivalent.
At 0.5 MPa it pushes 3927 N and pulls 3681 N; at 0.7 MPa it pushes 5497 N, with a theoretical max of 801 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement uses current CMSG/DMSG/EMSG sensors.
