Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-40S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-40S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 800mm 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 SAUJ100X800-40S
The AirTAC SAUJ100X800-40S is a double-acting single-rod profile cylinder with an on-site extend stroke trim of up to 40 mm. The nominal 800 mm stroke serves as the maximum, yielding a usable working range of 760-800 mm via an external stop screw. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at each end. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This 100 mm bore class delivers substantial power: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N push at 0.9 MPa. A practical computed insight from the 0.5 MPa data suggests a safe working load around 2356 N, or a vertical lift capacity of roughly 200 kg with a 2:1 margin. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors. For high-temperature environments up to 150 C, Viton H seals are available.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-40S Is Used
Large Press Feeders
Feeds heavy blanks into a press where the 40 mm stop screw dials in the exact material push distance during setup.
Pallet Positioning Stops
Acts as a heavy-duty end stop for large pallets, allowing 40 mm of field adjustment to accommodate varying load overhangs.
Divertor Gate Actuation
Drives a high-force divertor gate on a packaging line, using the adjustable extend stroke to fine-tune the diversion angle.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-40S the Right Cylinder?
When sizing this actuator, compare the 100 mm bore against the 80 mm option, which provides 2513 N push at 0.5 MPa. If 3927 N at 0.5 MPa is insufficient, stepping up is required. Choose the SAUJ over a fixed SAU when your machine assembly requires field tuning of the extend end position without buying a new cylinder. The 40 mm adjust window is ideal for final mechanical timing. Mounting options include Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Because the -S magnet is present, you can directly mount CMSG, DMSG, or EMSG switches. With an 800 mm stroke, you must manage side loads; use external guides to prevent rod bending and premature seal wear.
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 SAUJ100X800-40S FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull. Push force increases to 5497 N at 0.7 MPa, 7068 N at 0.9 MPa, and a theoretical max of 801 kgf at 1.0 MPa. The external stop screw shortens the extend stroke by up to 40 mm on-site, giving a usable range of 760-800 mm from the 800 mm maximum.
The -S suffix means a piston magnet is installed for CMSG, DMSG, or EMSG sensors. Regarding load holding, a plain cylinder does not hold its load on air loss; the piston drifts and the air cushion only decelerates near stroke end. The stop screw sets end position but is not a load lock. For a held load, use an external rod lock or pilot-operated check valve.
