Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-30
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X80-30 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 80mm 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 SAUJ100X80-30
The AirTAC SAUJ100X80-30 is a double-acting, double-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the nominal 80 mm stroke by up to 30 mm, yielding a usable working range of 50-80 mm without buying a new actuator. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at each end.
The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. Note this SKU lacks a magnet, so it cannot take a magnetic switch.

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 SAUJ100X80-30 Is Used
Press Fit Tuning
Allows operators to dial in the exact 50-80 mm extend position for seating bearings without swapping physical spacers.
Variable Carton Flap Folding
Provides adjustable end-stops to accommodate different box heights on a packaging line, trimming up to 30 mm on-site.
End-Of-Line Stopper Gate
Offers a field-adjustable physical barrier for pallets, letting maintenance shorten the stroke to match new pallet dimensions.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-30 the Right Cylinder?
Choose the SAUJ over a fixed SAU when your machine assembly requires precise end-position tuning during commissioning. The external stop sets the end position but is not a load lock; for dead-load holding you must add an external rod lock or pilot-operated check valve, as the cushion only decelerates. Mounting options include Basic, FA, and LB styles, sharing compatibility with the AirTAC SC series. Since this SKU has no -S suffix, it cannot accept CMSG or DMSG sensors. For the 80 mm stroke, side-load is minimal, but always guide the load rigidly.
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 SAUJ100X80-30 FAQ
The nominal 80 mm extend stroke can be shortened by up to 30 mm via the external stop screw, giving a 50-80 mm usable range. It uses a 1/2 inch port and 29 mm adjustable air cushions.
No, the stop screw only sets the extend end position; it is not a load lock. A plain cylinder drifts on air loss, and the cushion solely decelerates the piston near the end. For secure load holding, install an external rod lock or a pilot-operated check valve. Additionally, this specific SKU lacks a magnet, so it cannot support magnetic sensing.
