Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X800S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X800S-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 800mm 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 SAUF100X800S-08A
The SAUF100X800S-08A is a double-acting profile-type cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote valves and saving a manifold slot. The 100mm bore has a 1/2" air port, a 25mm rod, and an M20x1.5 rod-end thread. An integrated piston magnet supports CMSG/DMSG/EMSG switches.
The 4M310-08 valve has a 1/4" port, Cv 1.4 flow, and cycles up to 4 times per second. The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly within the 0.15-0.8 MPa valve window. At 0.5 MPa it pushes 3927 N and pulls 3681 N. A practical computed insight: the safe working load is about 2356 N (60% of the 0.5 MPa push force), translating to a vertical lift capacity of roughly 200 kg with a 2:1 margin.

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 SAUF100X800S-08A Is Used
Pallet Divertor
Decentralized diverting arm on a high-flow line. The built-in 4M310 valve handles the 100mm bore directly at the station without long tubing runs back to a main manifold.
Heavy Gate Actuator
One-signal switching for a 200kg vertical lifting gate. The integrated magnet allows position confirmation, while the 800mm stroke provides the necessary travel.
Press Ejection
Ejecting heavy parts from a press bed. The 4M310-08 valve delivers Cv 1.4 flow for rapid ejection, and the 5/2 configuration ensures reliable double-action cycling.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X800S-08A the Right Choice?
Size force between the 63mm bore (1559 N push) and this 100mm bore (3927 N push) at 0.5 MPa. This model uses an AC220V terminal entry coil with PT threads. The rod retracts when energised; reposition the valve to switch to extend-when-energised. Always size within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. For the 800mm 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 SAUF100X800S-08A FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa, reaching 6282 N push at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec) with an AC220V terminal entry coil. The cylinder body rates to 1.0 MPa, but the assembled unit must operate within the 0.15-0.8 MPa valve window.
By default, the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve on the cap. Note that the valve only routes air; it is not a load lock, so you need an external rod lock or pilot-operated check valve to hold a load on air loss.
