Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-100
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X800-100 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 SAUJ100X800-100
The AirTAC SAUJ100X800-100 is a double-acting, double-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 100 mm, giving a usable extend range of 700-800 mm without buying a new actuator. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions. The extruded aluminum profile barrel is noticeably shorter than an ISO 15552 cylinder of the same bore.
You can pair it with FA flange or LB foot mounts, and a high-temp Viton H seal option extends operation from -20 to +150 C. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

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 SAUJ100X800-100 Is Used
Large Press Dwell Tuning
Allows operators to fine-tune the 700-800 mm extend position on-site to set precise material forming depth without machining new hard stops.
Pallet Stop Calibration
Ideal for adjusting the extend stop distance to accommodate varying pallet lengths on a heavy-duty transfer line.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-100 the Right Cylinder?
Choose the SAUJ over a fixed-stroke SAU when your machine assembly requires field tuning of the end position within that 700-800 mm window. The external stop screw sets the end position but is not a load lock. For a nonstandard fixed length you would confirm from datasheet, but here the adjust code handles it. Because the stroke is 800 mm, you must use external guides to prevent rod bending and manage side loads. Mounting hardware is compatible with the AirTAC SC series only.
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 SAUJ100X800-100 FAQ
The nominal 800 mm extend stroke can be shortened by up to 100 mm via the external stop screw, yielding a 700-800 mm usable window. It uses a 1/2 inch port and 29 mm adjustable cushions.
No, the stop screw only sets the end position and the air cushion only decelerates the piston near stroke end; neither acts as a brake. If air is lost or the valve is centered, the piston will drift. For load holding, you must install an external rod lock or a pilot-operated check valve.
