Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900S-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 SAUF100X900S-08A
The SAUF100X900S-08A is a double-acting profile-type cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve mounted 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 cylinder of the same bore. This 100mm bore unit features a 1/2" cylinder port, an M20x1.5 rod thread, and a 29mm adjustable cushion.
It delivers 3927N push at 0.5MPa within the valve's 0.15-0.8MPa operating window. The safe working load is roughly 2356N, allowing a vertical lift of about 200kg with a 2:1 margin. The integrated valve flows 25mm2 (Cv 1.4) at 1/4", cycling up to 4 times per second. The AC220V terminal entry coil is IP65 rated. A piston magnet is included for CMSG/DMSG/EMSG switches.

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 SAUF100X900S-08A Is Used
Pallet Divertor
Uses the built-in 4M310-08 valve to locally switch a heavy divert arm without routing air lines back to a central manifold.
Vertical Lift Gate
Lifts a 200kg gate using the 100mm bore, relying on the integrated magnet for position feedback at stroke ends.
Long-Stroke Pusher
Pushes heavy workpieces 900mm, requiring external guides to manage side loads while saving a manifold slot.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X900S-08A the Right Choice?
Size between neighbours: the 80mm bore pushes 2513N at 0.5MPa, while this 100mm bore pushes 3927N. Confirm the AC220V terminal entry and 1/4" valve port meet your supply. The cylinder body rates to 1.0MPa, but you must size force within the built-in valve's 0.15-0.8MPa range. Default action retracts the rod when energised; reposition the valve to extend when energised. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold a load. For this 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 SAUF100X900S-08A FAQ
It pushes 3927N and pulls 3681N at 0.5MPa, reaching 6282N at 0.8MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port, Cv 1.4, and a 4 cycle/s limit. The cylinder body rates to 1.0MPa, but the assembled unit operates at 0.15-0.8MPa. The coil is AC220V with terminal entry.
By default, the rod retracts when the coil is energised; you can reposition the valve to extend when energised. The valve routes air and is not a load lock. The piston drifts on air loss, so add an external rod lock or pilot-operated check valve to hold a load.
