Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-40S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X75-40S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 75mm 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 SAUJ100X75-40S
The AirTAC SAUJ100X75-40S is a double-acting, double-rod profile cylinder with an on-site extend stroke adjustment. An external stop screw lets you shorten the 75 mm nominal stroke by up to 40 mm, yielding a usable extend range of 35-75 mm. It features a 1/2 inch port, an M20x1.5 rod thread, 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 piston magnet for CMSG, DMSG, or EMSG sensors. High-temperature Viton H seals can extend operation from -20 to +70 C up to 150 C.

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 SAUJ100X75-40S Is Used
Press Fit Tuning
Dialing in precise insertion depths for bearing presses where the exact 75 mm extend requires 40 mm of field adjustment to compensate for material tolerances.
Variable Height Sealing
Adjusting the extend endpoint on the fly for carton sealing heads, allowing operators to shorten the stroke by up to 40 mm for different package profiles.
Pallet Positioning Stops
Acting as a heavy-duty 100 mm bore stopper that can be fine-tuned on-site to position pallets accurately before stretch wrapping.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-40S the Right Cylinder?
Choose the SAUJ over a fixed-stroke SAU when your assembly requires field tuning of the end position rather than relying on external mechanical stops. The 40 mm adjust window is ideal for dialing in precise extend distances on-site. Basic, FA, and LB mountings are available, sharing compatibility with the AirTAC SC series. The -S magnet supports CMSG/DMSG/EMSG switches. Because the 75 mm stroke is under 300 mm, side-load risks are minimal, but always guide the load. The stop screw sets the end position and is not a load lock; supply air must remain live.
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 SAUJ100X75-40S FAQ
The 75 mm nominal extend stroke can be shortened by up to 40 mm via an external stop screw, giving a 35-75 mm usable range. It uses a 1/2 inch port and 29 mm adjustable cushions.
No, the stop screw only sets the extend end position; it is not a load lock. A plain cylinder drifts when air is lost or valves are centered, as the air cushion merely decelerates the piston near stroke end. For secure load holding, you must install an external rod lock or a pilot-operated check valve.
