Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-20
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X800-20 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 SAUJ100X800-20
The AirTAC SAUJ100X800-20 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 20 mm, giving a usable range of 780 to 800 mm. The 1/2 inch port and 29 mm adjustable air cushions manage high kinetic energy, while the extruded aluminum profile keeps the unit shorter than an ISO 15552 cylinder of the same bore.
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 SAUJ100X800-20 Is Used
Press Fit Tuning
Allows on-site stroke reduction of up to 20 mm to dial in the exact bottoming position for pressing bearings without remachining stops.
Pallet Stop Calibration
Provides adjustable end-positioning for diverter arms on conveyors, letting operators tweak the 800 mm extend distance to suit varying pallet widths.
Long-Reach Forming
Handles deep-draw forming tasks where the nominal stroke must be finely adjusted to control material deformation depth accurately.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-20 the Right Cylinder?
Choose the SAUJ over a fixed SAU when you need final end-position tuning during machine commissioning without swapping cylinders. The 20 mm adjust window is ideal for fine-tuning clamping pressure. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Because this SKU has no -S magnet, position sensing is unavailable. For the 800 mm stroke, always use external guides to prevent rod bending and manage side loads.
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 SAUJ100X800-20 FAQ
Push force rises to 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw allows you to shorten the 800 mm extend stroke by up to 20 mm on-site, yielding a 780 to 800 mm usable range.
No, this SKU lacks a -S magnet so it cannot accept CMSG or DMSG sensors. Additionally, a plain cylinder does not hold load on air loss; the piston drifts and the cushion only decelerates. For vertical load holding, install an external rod lock or pilot-operated check valve.
