This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X550, 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 SU100X550

About the Airtac SU63-100 Standard Cylinder SU100X550
The AirTAC SU100X550 is a discontinued double-acting profile-type cylinder with a 100mm bore and 550mm stroke. It delivers a robust 3927 N push force at 0.5 MPa, utilizing a 25mm piston rod and a 1/2 inch air port. AirTAC replaced this end-of-line unit with the SAU100X550 direct replacement, preserving the exact body profile, force output, and SC-series mounting compatibility.
This specific SKU lacks a magnet, so it cannot accept a position sensor. Additionally, the SAU upgrade introduces a SAUF variant with a built-in 4M solenoid valve, a self-switching feature absent in the original SU line.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X550 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 SAU100X550 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 SU100X550 Is Used
Pallet Lift Station
Lifts loaded pallets in a distribution hub, requiring an external pilot-operated check valve to hold the load safely if air pressure drops during the 550mm travel.
Mold Actuation
Secures heavy industrial molds on an SC-series center mount, where the 1/2 inch port supplies the necessary volume to move the 25mm rod rapidly.
Replacing the Airtac SU63-100 Standard Cylinder SU100X550 with the SAU100X550
To replace the SU100X550, order the SAU100X550, confirming the 100mm bore, 550mm stroke, 1/2 inch port, M20x1.5 rod thread, and SC-series mounting hardware. Because this SKU has no magnet, it cannot support legacy CS1-B/DS1-B switches; if sensing is needed, specify an SAU-S model and migrate to the current CMSG/DMSG/EMSG sensor family. When sizing, the 100mm bore yields 3927 N push and 3681 N pull at 0.5 MPa, while an 80mm neighbor provides 2513 N push. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for held loads. Finally, the 550mm stroke demands external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU100X550
- ✓ 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 SU100X550 FAQ
Yes, the SU100X550 is discontinued. The direct replacement is the AirTAC SAU100X550, which matches the 100mm bore, 550mm stroke, 3927 N force, 1/2 inch port, and SC-series mounting.
It 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. This specific SKU lacks a magnet and cannot take a sensor; the SAU-S replacement uses CMSG/DMSG/EMSG switches.
