This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X450, 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 SU100X450
The AirTAC Airtac SU63-100 Standard Cylinder SU100X450 is a double-acting profile-type standard cylinder with a Ø100mm bore and 450mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X450, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X450
The AirTAC SU100X450 is a discontinued double-acting profile-type standard cylinder featuring a 100mm bore and 450mm stroke. It delivers a robust 3927 N push force at 0.5 MPa and uses a 1/2" port with an M20x1.5 rod thread. AirTAC replaced this legacy unit with the SAU100X450, a direct upgrade retaining the exact same extruded aluminum body, bore, stroke, output force, port size, and SC-series mounting accessories.
Because this SKU lacks a magnet, it cannot accept a piston switch. The modern SAU100X450 replacement upgrades the sensor groove to support current CMSG, DMSG, and EMSG switches, and introduces the SAUF variant with a built-in 4M solenoid valve that the SU line never offered.

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 SAU100X450 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 SU100X450 Is Used
Heavy Stamping Press
Drives heavy-duty stamping and forming dies requiring high thrust over a 450mm travel distance.
Pallet Lift Station
Lifts loaded pallets vertically, utilizing the 200kg safe lifting capacity at 0.5 MPa.
Large Material Clamp
Secures bulky workpieces or structural components during machining and assembly operations.
Replacing the Airtac SU63-100 Standard Cylinder SU100X450 with the SAU100X450
To replace this discontinued SU100X450, order the SAU100X450 direct equivalent, verifying your 1/2" port, M20x1.5 rod thread, and SC-series mounting hardware. Since this specific SKU has no magnet (-S), it cannot support sensing; if your machine requires position detection, select an SAU100X450S and use the modern CMSG, DMSG, or EMSG sensor family instead of the legacy CS1-B or DS1-B switches. When sizing, the 100mm bore provides 3927 N push at 0.5 MPa; if you need less force, the neighboring 80mm bore offers 2513 N. Remember that a plain double-acting cylinder drifts without live air pressure, so fit an external rod lock or pilot-operated check valve for secure load holding. Finally, the 450mm stroke demands an external guide to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same bore / stroke → SAU100X450
- ✓ 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 SU100X450 FAQ
Yes, the SU100X450 is discontinued. The direct replacement is the AirTAC SAU100X450. It shares the identical 100mm bore, 450mm stroke, 1/2" port, output force, and SC-series mounting, so it drops directly into the same application.
At 0.5 MPa it provides 3927 N push and 3681 N pull force, rising to 5497 N at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot take a sensor; the SAU replacement supports CMSG, DMSG, and EMSG switches if sensing is required.
