This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X800, 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 SU100X800
The AirTAC SU63-100 Standard Cylinder SU100X800 is a double-acting profile-type standard cylinder with a Ø100mm bore and 800mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X800, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X800
The AirTAC SU100X800 is a discontinued double-acting profile-type cylinder with a 100 mm bore and 800 mm stroke. It delivers 3927 N push force at 0.5 MPa and features a 1/2" port with a 25 mm piston rod. AirTAC replaced this unit with the SAU100X800, a direct alternative retaining the exact same body dimensions, output force, and SC-series mounting hardware.
Because this is a non-magnet SKU, it cannot accept position sensors. If sensing is needed on the SAU100X800 upgrade, you must order the -S option which uses modern CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. Note that a plain cylinder drifts on air loss; the cushions only decelerate, so use a rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X800 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 SAU100X800 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 SU100X800 Is Used
Heavy Stamp Press Ejection
Uses the full 3927 N push at 0.5 MPa to knock heavy stamped metal panels clear of the lower die on every cycle.
Palletized Load Push-Off
The 800 mm stroke provides the long traverse needed to push assembled pallet loads from a transfer deck onto a chain conveyor.
Large Assembly Fixture Clamping
Secures bulky machinery housings during machining, relying on the 25 mm rod to resist deflection across the extended length.
Replacing the Airtac SU63-100 Standard Cylinder SU100X800 with the SAU100X800
To replace the SU100X800, order the SAU100X800. Confirm the 1/2" port, M20x1.5 rod thread, and your SC-series mounting (LB/FA/FB/CA/CB). This non-magnet model cannot take a sensor; if you need switches on the SAU, add the -S option and migrate to CMSG/DMSG/EMSG sensors. Sizing checks: stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N. For the 800 mm stroke, prevent rod bending by using an external guide to absorb side loads. The cylinder will not hold a load without live air—install a pilot-operated check valve or external rod lock. The SAUF variant adds a built-in 4M valve if you need integrated control.
Replacement checklist
- ✓ Same bore / stroke → SAU100X800
- ✓ 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 SU100X800 FAQ
Yes, the SU100X800 is discontinued. The direct replacement is the AirTAC SAU100X800. It matches the 100 mm bore, 800 mm stroke, 1/2" port, and SC-series mounting accessories. You simply order the SAU100X800 for an identical installation footprint.
It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot accept sensors. The SAU100X800-S replacement supports modern CMSG/DMSG/EMSG switches, replacing the legacy CS1-B/DS1-B.
