Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-20S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X80-20S 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 SAUJ100X80-20S
The AirTAC SAUJ100X80-20S is a double-acting double-rod profile cylinder with an on-site extend stroke trim of up to 20 mm. Its external stop screw lets you dial the usable extend stroke down from the 80 mm maximum to 60 mm, eliminating the need to buy a fixed-length unit for every minor machine variation. The hard-anodized extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG position sensing.

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 SAUJ100X80-20S Is Used
Press Fit Tuning
Dial in the exact insertion depth of bearings or pins on-site using the 20 mm stop screw window, ensuring perfect seating without over-stressing the part.
Variable Depth Sealing
Adjust the extend stroke on a carton sealing or forming head to accommodate different package heights, using the 60 to 80 mm usable range.
Component Clamping
Securely hold varying castings in a machining fixture; the 100 mm bore delivers 3927 N at 0.5 MPa while the stop screw sets the precise clamp position.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-20S the Right Cylinder?
Choose the SAUJ over a fixed SAU when your assembly needs slight positional tweaking after installation, as the 20 mm stop screw window prevents costly cylinder swaps. Basic, FA flange, and LB foot mountings are available, and mounting compatibility is with the AirTAC SC series only. The included -S magnet allows electronic or reed switch mounting. Because the nominal 80 mm stroke is well under the 300 mm side-load threshold, guide rails are less critical here, but always support off-center loads. Operating pressure is 0.15-1.0 MPa.
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 SAUJ100X80-20S FAQ
The theoretical max is 801 kgf at 1.0 MPa. The nominal 80 mm extend stroke can be shortened by up to 20 mm on-site via an external stop screw, yielding a 60 to 80 mm usable range.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG position switches. 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. The stop screw sets end position but is not a load lock. For held loads, use an external rod lock or pilot-operated check valve.
