Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900-08A 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 SAUF100X900-08A
The SAUF100X900-08A is a double-acting profile cylinder with a built-in AirTAC 4M310 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 is shorter than an ISO 15552 unit of the same bore. This 100mm bore uses a 1/2" cylinder port, a 1/4" valve port, and a 25mm piston rod.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 3927 N push force at 0.5 MPa. The integrated valve flows 25 mm2 (Cv 1.4) at up to 4 cycles per second. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 2356 N, allowing a vertical lift of about 200 kg with a 2:1 margin. This SKU lacks a magnet and cannot accept a sensor.

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)

|---|---|---|
| 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 SAUF100X900-08A Is Used
Pallet Diversion
Decentralized pallet routing on a long conveyor. The built-in valve provides local switching for the 900mm reach without running long control tubes back to a central manifold.
Vertical Material Lift
Lifting heavy totes in an automated warehouse. The 100mm bore handles the load safely, while the integrated AC220V coil simplifies electrical wiring at the pick station.
Press Ejection
Ejecting finished parts from a large stamping press. One signal directly cycles the cylinder, removing the need for a dedicated remote valve island on the machine frame.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900-08A the Right Choice?
Size by comparing neighbor bores: the 80mm bore yields 2513 N push at 0.5 MPa, while this 100mm bore provides 3927 N. Confirm the AC220V terminal entry and PT thread meet your control voltage. The rod retracts when the coil energizes; reposition the valve to switch to extend-when-energised. Because the 4M310 valve routes air, it is not a load lock—add an external rod lock or pilot-operated check valve to hold loads. The cylinder body rates to 1.0 MPa, but the assembled unit must operate at 0.15-0.8 MPa. For the 900mm stroke, use external guides to prevent rod bending and side-load damage.
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 SAUF100X900-08A FAQ
It generates 3927 N push and 3681 N pull at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow) running an AC220V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
No remote valve is needed; the integrated 4M310 valve switches the cylinder directly. However, the valve only routes air and is not a lock. The rod drifts on air loss, so you must add an external rod lock or pilot-operated check valve for vertical load holding.
