Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X500S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X500S-08A is a genuine double-acting profile-type cylinder with a Ø100mm bore, 500mm 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 SAUF100X500S-08A
The SAUF100X500S-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 100mm bore delivers 3927N push and 3681N pull at 0.5MPa, with a 1/2" cylinder port and M20x1.5 rod thread.
This unit includes a piston magnet for CMSG/DMSG/EMSG switches. The integrated valve has a 1/4" port, Cv 1.4 flow, and runs at 4 cycles/sec. The cylinder body rates to 1.0MPa, but the valve limits operation to 0.15-0.8MPa. For sizing, the safe working load is roughly 2356N (60% of the 0.5MPa push force), yielding a 200kg vertical lift capacity 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 SAUF100X500S-08A Is Used
Automated Press Station
Decentralized actuation for a 200kg press head, using the built-in valve to eliminate long tubing runs from a central manifold.
Heavy Divert Gate
Switches a large divert gate directly at the actuator, saving a manifold slot and simplifying maintenance on the line.
Pallet Lift Unit
Lifts pallets within a 2356N safe working load, relying on the integrated 4M310 valve for rapid local 4Hz cycling.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X500S-08A the Right Choice?
Select this 100mm bore over the 80mm option when you need higher thrust, stepping down to 63mm if 1559N push at 0.5MPa is sufficient. Confirm the AC220V terminal entry and PT thread match your supply. The 4M310-08 valve restricts working pressure to 0.15-0.8MPa despite the 1.0MPa cylinder rating. Default action retracts the rod when energised; reposition the valve to extend on signal. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold loads. For the 500mm 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 SAUF100X500S-08A FAQ
It pushes 3927N and pulls 3681N at 0.5MPa, reaching 6282N at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4 cycles/sec) running on AC220V. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within 0.15-0.8MPa.
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve on the cap. This self-switching design means one signal drives the cylinder without needing a separate remote valve.
