Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X500-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X500-08A 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 SAUF100X500-08A
The SAUF100X500-08A is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M310 5/2 solenoid valve on the cap. One coil signal drives the 500mm stroke, eliminating remote plumbing and saving a manifold slot. The 100mm bore has a 1/2 inch cylinder port, a 25mm rod, and M20x1.5 rod thread.
It operates within the valve's 0.15-0.8 MPa window, delivering 3927N push at 0.5MPa. The integrated valve has a 1/4 inch port, Cv 1.4, and runs up to 4 cycles/sec. For sizing, the safe working load is roughly 2356N (60% of the 0.5MPa push), allowing a 200kg vertical lift with a 2:1 margin. This terminal-entry AC220V SKU lacks a magnet (-S), so it cannot accept 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 SAUF100X500-08A Is Used
Heavy Stamp Feeder
Uses one coil signal to push heavy blanks into a press, saving manifold space while delivering 3927N push at 0.5MPa.
Pallet Diverter
Decentralized 500mm stroke diverts large pallets on a high-speed line without running long tubing to a remote valve bank.
Vertical Gate Actuator
Lifts a 200kg loading dock gate with a 2:1 safety margin, relying on the integrated 4M310 valve for direct switching.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X500-08A the Right Choice?
Size against the 63mm and 100mm bores: the 63mm bore yields 1559N push while this 100mm bore yields 3927N push at 0.5MPa. Confirm the AC220V terminal entry and PT threads suit your control panel. The cylinder body rates to 1.0MPa, but you must size force within the 4M310 valve's 0.15-0.8MPa working range. Default action retracts the rod when energised, but you can reposition the valve to extend-when-energised. Because the 500mm stroke risks rod bending, add external guides to handle side loads. The valve routes air and is not a lock; for load holding on air loss, install an external rod lock or pilot-operated check valve.
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 SAUF100X500-08A FAQ
It delivers 3927N push and 3681N pull at 0.5MPa, and up to 6282N push at 0.8MPa. The built-in valve is a 4M310-08 (1/4 inch port, Cv 1.4, max 4 cycles/sec). The cylinder body rates to 1.0MPa, but the assembled unit must operate in the 0.15-0.8MPa valve window. It uses an AC220V terminal-entry coil.
No, the built-in valve only routes air and is not a load lock; the piston drifts on air loss. For load holding, add an external rod lock or pilot-operated check valve. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised.
