Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700S-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 700mm stroke and a built-in 4M210-08 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 SAUF40X700S-08A
The SAUF40X700S-08A is a double-acting profile cylinder with a built-in AirTAC 4M 5/2 solenoid valve 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 40mm bore unit has a 1/4" cylinder port and a 700mm stroke.
It uses a 4M210-08 valve (1/4" port, Cv 0.89, 5 cycles/s). The coil is AC220V with terminal entry. The cylinder body rates to 1.0 MPa, but size force within the valve's 0.15-0.8 MPa window. At 0.5 MPa it pushes 628N and pulls 528N. The safe working load is about 377N, allowing a vertical lift of roughly 32kg with a 2:1 margin. The S suffix means a piston magnet is present 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAUF40X700S-08A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate. One AC220V signal actuates the 700mm stroke without tubing back to a central manifold.
Long-Reach Pallet Stop
Ideal for extended pallet stops. The built-in 4M210-08 valve handles the 5 cycle/s demand right at the actuator.
Independent Machine Gate
Uses the S suffix magnet with CMSG switches for position feedback on standalone safety gates across the 700mm travel.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700S-08A the Right Choice?
Size against the 40mm bore force: 628N push and 528N pull at 0.5 MPa. The neighbouring 32mm bore yields 402N push, while the 50mm bore yields 982N push. Confirm the AC220V terminal entry meets your control voltage. Default action retracts the rod when energised; reposition the valve to extend on signal. The assembled unit operates at 0.15-0.8 MPa, not the 1.0 MPa cylinder body limit. The valve routes air and is not a lock; for load holding add an external rod lock or pilot-operated check valve. For the 700mm 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 SAUF40X700S-08A FAQ
It pushes 628N and pulls 528N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89). The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
The default action retracts the rod when the coil is energised. You can reconfigure it to extend when energised by repositioning the built-in valve. This self-switching design removes the need for a remote valve.
