This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X145S, 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 SU100X145S
The AirTAC Airtac SU63-100 Standard Cylinder SU100X145S is a double-acting profile-type standard cylinder with a Ø100mm bore and 145mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X145S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X145S
The AirTAC SU100X145S is a discontinued double-acting profile-type cylinder with a 100mm bore and 145mm stroke. It delivers 3927N push force at 0.5MPa via a 1/2" port. The direct replacement is the SAU100X145S, matching the exact bore, stroke, output force, port size, and SC-series mounting.
The SAU upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S model, and offers a new SAUF valve-integrated variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X145S 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 SAU100X145S 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 SU100X145S Is Used
Heavy Press Clamping
Secures large metal castings during machining, utilizing the 3927N push force at 0.5MPa to hold components firmly against the cutting tool vibration.
Pallet Reject Arm
Pushes overweight or misaligned pallets off a high-speed conveyor line, where the 145mm stroke provides the exact reach needed to clear the belt path.
Mold Ejection Station
Ejects dense injected plastic parts from heavy tooling, relying on the compact extruded aluminum profile to fit within tight press boundaries.
Replacing the Airtac SU63-100 Standard Cylinder SU100X145S with the SAU100X145S
To replace this SU100X145S, order the SAU100X145S direct equivalent, verifying the 1/2" port, M20x1.5 rod thread, and SC-series mounting. If downsizing, a 80mm bore yields 2513N push at 0.5MPa; if upsizing, note the 100mm bore already hits 801kgf max at 1.0MPa. Because this is a 145mm stroke, ensure adequate guide support to prevent rod bending under heavy lateral loads. The -S magnet means you must migrate from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock for held loads. The SAUF variant adds a built-in valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU100X145S
- ✓ 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 SU100X145S FAQ
Yes, the SU100X145S is discontinued. The direct replacement is the SAU100X145S. It matches the 100mm bore, 145mm stroke, 1/2" port, force, and SC-series mounting, but the -S magnet now requires CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B.
The 1/2" port bore delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, and a maximum theoretical force of 801kgf at 1.0MPa. Operating speed is 30-800mm/s.
