Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-75S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-75S 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 SAUJ100X800-75S
The AirTAC SAUJ100X800-75S is a double-acting single-rod profile cylinder with an on-site extend-stroke trim window. The external stop screw lets you shorten the 800 mm nominal stroke by up to 75 mm, yielding a usable 725-800 mm extend position. It features a 100 mm bore, a 1/2 inch port, and a 25 mm rod with an M20x1.5 thread. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This bore delivers robust force: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N at 0.9 MPa. A safe working load is roughly 2356 N (about 60 percent of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. The -S suffix means a piston magnet is built in for CMSG, DMSG, or EMSG sensors. Adjustable 29 mm air cushions manage end-of-stroke deceleration.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-75S Is Used
Heavy Press Tonnage
Apply up to 7068 N of push force at 0.9 MPa for forming or stamping operations, with the 75 mm stop screw allowing exact bottom-dead-center field calibration.
Large Pallet Diversion
Actuate heavy transfer arms on packaging lines; the 1/2 inch port and 100 mm bore provide the airflow and power needed to shift loaded pallets smoothly.
Vertical Lift Gates
Lift 200 kg materials using the 0.5 MPa thrust rating; the adjustable extend window lets you fine-tune the gate opening height on-site without changing hardware.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-75S the Right Cylinder?
When sizing this unit, look both ways: a 100 mm bore yields 3927 N push at 0.5 MPa, while an 80 mm bore gives 2513 N. Choose the 100 mm if you need the extra thrust for heavy payloads. Pick this SAUJ over a fixed SAU when your machine assembly requires field tuning of the extend end position without buying a new cylinder. The 75 mm adjust window is set via the external stop screw. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. The -S magnet supports CMSG/DMSG/EMSG switches. Because the stroke is 800 mm, use external guides to prevent rod bending and manage side loads. Remember the stop screw sets 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 SAUJ100X800-75S FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull. Push force is 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 nominal stroke is 800 mm. The external stop screw allows you to shorten the extend stroke by up to 75 mm on-site, giving a usable extend range of 725-800 mm.
The -S suffix indicates a built-in piston magnet for direct mounting of CMSG, DMSG, or EMSG reed or electronic switches. Regarding load holding: a plain cylinder does not hold its load on air loss or when the valve is centered. The piston will drift, and the 29 mm air cushion only decelerates near the end of stroke. For a held load, install an external rod lock or a pilot-operated check valve.
