Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X1000-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X1000-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 1000mm 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 SAUF40X1000-08A
The SAUF40X1000-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 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 unit of the same bore. This bore uses a 1/4" cylinder port, a Ø16 mm rod, and an M12x1.25 rod-end thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 628 N push at 0.5 MPa. The 1/4" valve port gives 16 mm2 flow (Cv 0.89) and handles up to 5 cycles/sec. The AC220V terminal coil is IP65 rated. For sizing, the safe working load is roughly 377 N, and vertical lift capacity is about 32 kg with a 2:1 margin. Because this SKU lacks the S suffix, it cannot accept a magnetic sensor.

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 SAUF40X1000-08A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a long conveyor line. The integrated valve eliminates long tube runs back to a central manifold, speeding up the 1000 mm sorting stroke.
Remote Pusher Station
Ideal for a standalone pallet pusher in a large warehouse. The built-in 4M210-08 valve means a single AC220V wire drop actuates the pusher without extra plumbing.
Long-Stroke Machine Door
Operates a 1-meter automated equipment guard door. The compact profile barrel saves space while the self-contained switching simplifies installation across the factory floor.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X1000-08A the Right Choice?
Size force between the 0.15-0.8 MPa valve limits: this 40 mm bore yields 628 N push at 0.5 MPa, whereas the neighboring 50 mm bore offers 982 N. The 1000 mm stroke is within the 1200 mm standard maximum but requires an external guide to prevent rod bending under side loads. Confirm the AC220V terminal entry suits your control system. The rod retracts when the coil is energised; repositioning the valve changes it to extend-when-energised. Without air, the valve routes flow but does not lock the piston, so add an external rod lock or pilot-operated check valve for held 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 SAUF40X1000-08A FAQ
It generates 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec max) driven by an AC220V terminal coil. Although the cylinder body rates to 1.0 MPa, you must size force within the assembled valve's 0.15-0.8 MPa operating window.
Yes, you can reconfigure the default retract action to extend-when-energised simply by repositioning the valve. The 5/2 valve only routes air; it is not a load lock. If power or air drops, the piston drifts, so install an external rod lock or pilot-operated check valve for suspended loads.
