Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-75S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X80-75S 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 SAUJ100X80-75S
The AirTAC SAUJ100X80-75S is a double-acting double-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the 80 mm nominal stroke by up to 75 mm, yielding a usable working range of 5-80 mm. It features a 1/2 inch port, an M20x1.5 piston rod, and 29 mm adjustable air cushions. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
The -S suffix indicates a built-in magnet for CMSG, DMSG, or EMSG sensors. For high-heat environments up to 150 C, Viton H seals are available.

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 SAUJ100X80-75S Is Used
Press Fit Tuning
Allows operators to dial in the exact 5-80 mm extend position for inserting bearings without reprogramming a PLC or swapping actuators.
Variable Depth Sealing
Adjusts the extend stroke on-site to match different carton heights, ensuring precise sealing pressure for varied packaging formats.
Prototype Forming
Provides a 75 mm adjustment window for short-stroke pressing tasks, letting engineers test multiple material thicknesses rapidly.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-75S the Right Cylinder?
Choose this SAUJ model over a fixed-stroke SAU when your assembly requires manual end-position tuning without buying new hardware. It supports Basic, FA flange, and LB foot mounts, sharing mounting compatibility with the AirTAC SC series. The -S option enables electronic or reed sensor tracking. Since the nominal stroke is only 80 mm, side-load guide concerns are minimal, but always ensure rigid load alignment. Note the external stop sets the end position but is not a load lock.
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 SAUJ100X80-75S FAQ
This 100 mm bore cylinder pushes 3927 N and pulls 3681 N at 0.5 MPa. It reaches 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, with a max theoretical force of 801 kgf at 1.0 MPa. The external stop screw shortens the 80 mm extend stroke by up to 75 mm, giving a 5-80 mm usable range.
The -S suffix means a piston magnet is installed for CMSG, DMSG, or EMSG sensors. Regarding load holding, the cylinder does not lock the load on air loss; the piston drifts and the 29 mm cushion only decelerates near stroke end. Use an external rod lock or pilot-operated check valve for secure holding.
