Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-40S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X80-40S 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 SAUJ100X80-40S
The AirTAC SAUJ100X80-40S is a double-acting double-rod profile cylinder with an on-site stroke adjustment. An external stop screw lets you shorten the extend stroke by up to 40 mm, giving a usable working range of 40 to 80 mm. The 80 mm nominal stroke serves as the maximum travel. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. The -S suffix means a piston magnet is built in for CMSG, DMSG, or EMSG 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 SAUJ100X80-40S Is Used
Press Fit Tuning
Allows operators to dial in the exact 40 to 80 mm extend position for pressing bearings without swapping physical spacers.
Variable Diverter Gate
Provides adjustable reach for a sorting gate, letting maintenance shorten the extend stroke by 40 mm to accommodate new package sizes.
Adjustable Stopper Arm
Sets a precise physical stop for heavy pallets on a roller line, fine-tuning the contact point on-site to handle different pallet depths.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-40S the Right Cylinder?
If your application demands more than 3927 N, step up the pressure to achieve 5497 N at 0.7 MPa. Choose the SAUJ over a fixed SAU when you need on-site extend length tuning without buying a new cylinder. The 40 mm adjust window is ideal for finalizing exact end positions during machine commissioning. Basic, FA, and LB mountings are available, sharing compatibility with the AirTAC SC series. The -S magnet supports CMSG/DMSG/EMSG switches. For any stroke exceeding 300 mm, always use external guide rails to prevent side-load damage.
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 SAUJ100X80-40S FAQ
Push increases 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 80 mm nominal extend stroke by up to 40 mm on-site, yielding a 40 to 80 mm usable range. The stop sets the end position and is not a load lock.
The -S suffix indicates a built-in piston magnet for mounting CMSG, DMSG, or EMSG electronic or reed sensors directly onto the profile barrel. Note that a plain cylinder does not hold load on air loss; the piston drifts and the 29 mm air cushion only decelerates near stroke end. For secure load holding, install an external rod lock or a pilot-operated check valve.
