Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 900mm stroke and a built-in 4M310-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900-08B
The SAUF100X900-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/2" cylinder port, an M20x1.5 rod thread, and 29mm adjustable cushions.
Operating in the 0.15-0.8 MPa valve window, it delivers 3927 N push force at 0.5 MPa. The DC24V terminal entry coil offers IP65 protection and a 0.05s response. For sizing, the safe working load is roughly 2356 N, allowing a vertical lift of about 200 kg with a 2:1 margin. The 4M310 valve provides a Cv of 1.4 and handles up to 4 cycles per second. This SKU lacks the S suffix, so it cannot take a magnetic switch.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAUF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAUF datasheet. Port options: PT / G.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAUF does not hold its load without air — the valve routes air, it is not a lock. For a held load, add an external rod lock or a pilot-operated check valve.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900-08B Is Used
Decentralized Pallet Diversion
Drives a large diverter arm directly on the conveyor frame. The integrated 4M310 valve means one DC24V signal extends the 900mm rod without running long tubing back to a central manifold.
Vertical Lift Gate Actuation
Raises and lowers a heavy material gate. Providing 3927 N push at 0.5 MPa, it safely lifts 200 kg loads with a 2:1 margin while saving manifold space in the control cabinet.
Machine Guard Door Control
Opens a tall automated guard door. The compact profile fits tight machine cavities, and the built-in valve simplifies wiring to a single local output for reliable 4 cycles per second operation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900-08B the Right Choice?
Size this 100mm bore against the 63mm and 80mm neighbors using the 0.5 MPa figures: 100mm gives 3927 N push, while 80mm gives 2513 N. Confirm the DC24V terminal coil matches your supply. The default action retracts the rod when energized; reposition the valve to extend on signal. Size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. For the 900mm stroke, use external guides to prevent rod bending and side-load wear.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900-08B FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec) driven by a DC24V terminal coil. Although the cylinder body rates to 1.0 MPa, you must size force within the 0.15-0.8 MPa valve operating window.
No. The 4M310 valve routes air but is not a load lock; air loss causes the piston to drift. For vertical holding you must add an external rod lock or pilot-operated check valve. Also, because this SKU lacks the S suffix, it cannot accept a magnetic position sensor.
