Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-30
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X800-30 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 800mm stroke, 1/2" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-30
The AirTAC SAUJ100X800-30 is a double-acting double-rod profile cylinder with an adjustable extend stroke. An external stop screw lets you trim the extend stroke by up to 30mm on-site, giving a usable working range of 770-800mm. This avoids buying a custom cylinder when you need fine end-position tuning. It features a 1/2 inch port and a hard-anodized extruded aluminum barrel, making it shorter than an ISO 15552 cylinder of the same 100mm bore.
The adjustable air cushions are 29mm at each end. Note this SKU lacks a magnet (-S), so it cannot take CMSG or DMSG sensors. For high-heat environments up to 150C, Viton H seals are available.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-30 Is Used
Press Fit Tuning
Final press depth varies slightly by material batch. Trim the extend stroke by up to 30mm on-site to set the exact insertion depth without swapping cylinders.
Pallet Stop Adjustment
Actuate a heavy 200kg pallet stop gate. The 100mm bore provides the push force needed, and the stop screw fine-tunes the gate resting position for different pallet widths.
Heavy Load Diverter
Push heavy cartons on a sorting line. The 770-800mm working stroke handles large items, while the external guide rails absorb side-load forces during the 800mm travel.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-30 the Right Cylinder?
Choose the SAUJ over a fixed SAU when your machine assembly needs on-site stroke tuning without machining external hard stops. The 30mm adjust window is ideal for final mechanical timing. Mounting options include Basic, FA flange, and LB foot, with compatibility matching the AirTAC SC series. Because this is a non-magnetized SKU, you cannot mount position sensors. With an 800mm stroke, you must support the load with external guides to prevent rod bending and excessive side-loading. The stop screw sets the end position but is not a load lock; without live air the piston drifts, so use an external rod lock or pilot-operated check valve for holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-30 FAQ
The theoretical max is 801kgf at 1.0MPa. The nominal 800mm extend stroke is the maximum; an external stop screw lets you shorten it by up to 30mm on-site, yielding a 770-800mm usable range. It uses a 1/2 inch port and 29mm adjustable air cushions.
This specific SKU lacks the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG magnetic switches. Regarding load holding, the cylinder does not hold its load on air loss or when the valve is centered; the piston drifts and the cushion only decelerates near the end. The stop screw sets the end position but is not a brake. For secure load holding, install an external rod lock or a pilot-operated check valve.
