Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-40
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X80-40 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 SAUJ100X80-40
The AirTAC SAUJ100X80-40 is a double-acting, double-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the 80mm nominal stroke by up to 40mm, yielding a usable 40-80mm working window. This hard-anodized aluminum extrusion is notably shorter than an ISO 15552 cylinder of the same bore. It features a 25mm rod, M20x1.5 rod thread, and a 1/2 inch port.
It includes 29mm adjustable air cushions at each end. 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 SAUJ100X80-40 Is Used
Press Fit Depth Tuning
Ideal for light press operations where the exact insertion depth of a bearing requires field adjustment via the external stop screw.
Variable Height Pallet Stops
Useful on conveyor lines where pallets of varying heights need the extend stroke shortened on-site to act as an adjustable physical end stop.
Adjustable Clamping Fixtures
Suits clamping stations holding parts of different widths, allowing operators to trim the extend stroke by up to 40mm without changing hardware.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-40 the Right Cylinder?
If your application needs less force, step down to the 80mm bore. Choose the SAUJ over a fixed SAU when your machine assembly requires on-site end-position tuning without buying multiple cylinders. The 40mm adjust window is ideal for fine-tuning clamping or pressing depth. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Since the 80mm stroke is under 300mm, side-load guide concerns are minimal, but always guide the load. This non-magnetic SKU cannot support position sensing.
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 SAUJ100X80-40 FAQ
Push force is 5497N at 0.7MPa, 7068N at 0.9MPa, and the theoretical max is 801kgf at 1.0MPa. The 80mm nominal extend stroke can be shortened by up to 40mm on-site using the external stop screw, giving a usable range of 40-80mm.
No. A plain cylinder does not hold its load on air loss or when the valve is centered; the piston drifts. The 29mm adjustable air cushion only decelerates the piston near the stroke end and the stop screw only sets the end position. For a held load, you must use an external rod lock or a pilot-operated check valve.
