Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X700S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X700S-08A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 700mm 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 SAUF63X700S-08A
The SAUF63X700S-08A is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 63mm bore has a 3/8 inch air port and a 20mm rod with an M16x1.5 thread. An integrated piston magnet allows switch mounting.
Operating in the 0.15-0.8 MPa valve window, it delivers 1559N push and 1402N pull at 0.5 MPa. The 1/4 inch valve port flows 25 mm2 (Cv 1.4) at up to 4 cycles per second. The AC220V terminal coil is IP65 rated. For sizing, the safe working load is about 935N, yielding a 79kg 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 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 SAUF63X700S-08A Is Used
Conveyor Diverter
Decentralized diverter gate on a long conveyor. The built-in valve provides local switching without running long tubing back to a central manifold.
Pallet Stopper
Independent pallet stop in a packaging line. One AC220V signal actuates the 700mm stroke, saving manifold slots for nearby actuators.
Machine Guard Gate
Remote access gate on a large machine. The integrated 4M310 valve simplifies installation and eliminates extra plumbing across the frame.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X700S-08A the Right Choice?
Size against the 63mm bore (1559N push at 0.5 MPa) or the neighbouring 50mm (982N) and 80mm (2513N) options. Confirm the AC220V terminal entry and PT threads. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. At 700mm stroke, use external guides to prevent rod bending and side loads.
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 SAUF63X700S-08A FAQ
It pushes 1559N and pulls 1402N at 0.5 MPa. The built-in valve is a 4M310-08 (1/4 inch port, Cv 1.4, 4 cycles/s max) driven by an AC220V terminal coil. The cylinder body rates to 1.0 MPa, but you must size force within the 0.15-0.8 MPa assembled valve window.
By default the rod retracts when the coil is energised, but you can reconfigure it to extend by repositioning the valve. The valve only routes air; it is not a load lock. The piston drifts on air loss, so add an external rod lock or pilot-operated check valve for load holding.
