This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X550S, 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 SU100X550S
The AirTAC SU63-100 Standard Cylinder SU100X550S is a double-acting profile-type standard cylinder with a Ø100mm bore and 550mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X550S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X550S
The AirTAC SU100X550S is a discontinued double-acting profile-type cylinder with a 100mm bore and 550mm stroke. Delivering 3927 N push and 3681 N pull at 0.5 MPa, its direct replacement is the SAU100X550S. The SAU retains the same extruded aluminium body, 1/2" port, M20x1.5 rod thread and SC-series mounting accessories.
Upgrading to the SAU100X550S keeps the 29 mm adjustable air cushions and 30-800 mm/s speed unchanged, but introduces notable improvements. The -S magnet on this legacy SU operated with older CS1-B / DS1-B switches, whereas the SAU replacement utilises the current CMSG / DMSG / EMSG sensor family. Furthermore, the SAU line offers a SAUF variant featuring a built-in 4M solenoid valve for self-switching operation, an option the SU series never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X550S 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 SAU100X550S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SU100X550S Is Used
Heavy Press Ejection
Ideal for pushing heavy stampings out of a hydraulic press, using the 3927 N push force at 0.5 MPa to reliably clear thick metal blanks.
Pallet Diverting
Drives large loaded pallets across conveyor lanes, where the 100mm bore handles high lateral mass and the 550mm stroke shifts the load completely clear.
Replacing the Airtac SU63-100 Standard Cylinder SU100X550S with the SAU100X550S
To replace the SU100X550S, order the SAU100X550S and verify your 1/2" port thread (PT, G or NPT) and SC-series mounting (LB, FA, FB, CA, CB). Because this 550 mm stroke exceeds 300 mm, you must support the load with external guides to prevent rod bending and premature seal wear from side loads. If sizing alternatives, a neighbouring 80mm bore provides 2513 N push at 0.5 MPa, while this 100mm bore reaches 5497 N at 0.7 MPa. Remember that a standard cylinder drifts without live air; the cushions only decelerate at stroke end, so fit an external rod lock or pilot-operated check valve for held loads. Finally, if ordering the SAU, note the -S magnet now requires CMSG/DMSG/EMSG switches, and consider the SAUF valve-integrated body if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU100X550S
- ✓ 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 SU100X550S FAQ
Yes, the AirTAC SU100X550S is discontinued and end-of-life. The direct replacement is the SAU100X550S. It provides identical bore, stroke, output force, 1/2" port size and SC-series mounting compatibility, fitting the exact same application space.
The 100mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 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 SAU100X550S replacement requires the current CMSG/DMSG/EMSG sensor family.
