Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-20
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X80-20 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 SAUJ100X80-20
The AirTAC SAUJ100X80-20 is a double-acting double-rod profile cylinder with an on-site extend stroke trim of up to 20mm via an external stop screw. The nominal 80mm stroke is the maximum; you can shorten it to a 60mm usable length. It features a 1/2 inch port, an M20x1.5 rod thread, and 29mm adjustable air cushions. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
Choose this adjustable unit over a fixed SAU plus external stop to save build space and simplify mechanical alignment.

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 SAUJ100X80-20 Is Used
Press Fit Calibration
Dial in the exact 60-80mm extend position for seating bearings without swapping cylinders or machining limit spacers.
Diverter Gate Adjustment
Tune the extend stop on-site to alter the gate angle for different package sizes on a packaging line.
Pallet Stop Tuning
Adjust the 20mm window to set the precise pallet stop height for varying load widths on a conveyor.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-20 the Right Cylinder?
If 3927N is excessive, drop to the 80mm size. The 20mm adjust window is ideal for fine-tuning the 80mm nominal extend to a precise 60-80mm endpoint without machining spacers. Mounting options include Basic, FA flange, and LB foot, matching the AirTAC SC series footprint. This SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. For any stroke over 300mm, guide the load to prevent side-load damage. Note that the stop screw sets end position but does not lock the load; without live air the piston drifts, so fit an external rod lock 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 SAUJ100X80-20 FAQ
The 80mm nominal extend stroke can be shortened by up to 20mm on-site using the external stop screw, yielding a 60-80mm usable range.
No, this SKU lacks a magnet and cannot accept CMSG or DMSG sensors. The stop screw only sets the end position; it is not a load lock. The cushion solely decelerates. Without live air the piston drifts, so use an external rod lock or pilot-operated check valve for load holding.
