Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X1000S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X1000S-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 SAUF40X1000S-08A
The SAUF40X1000S-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 makes it shorter than an ISO 15552 unit of the same bore. This 40mm bore has a 1/4" cylinder port, an M12x1.25 rod thread, and a 1000mm stroke.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 628N push and 528N pull at 0.5 MPa. The valve flows 16 mm2 (Cv 0.89) at up to 5 cycles/s. The AC220V terminal coil is IP65 rated with a 0.05s response. Computed buyer insight: safe working load is roughly 377N (60% of the 0.5MPa push), yielding a 32kg vertical lift capacity with a 2:1 margin. The -S suffix provides a piston magnet 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 SAUF40X1000S-08A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate. The integrated 4M210-08 valve fires the 1000mm stroke from a single AC220V signal without running long tubing back to a central manifold.
Remote Machine Guard Gate
Ideal for isolated guard doors on large equipment. The built-in valve handles 5 cycles/s, and the -S magnet tracks gate position via CMSG switches for safety interlocks.
Long-Reach Package Pusher
Pushes parcels along a sorting line using the full 1000mm stroke. The 40mm bore provides 628N push at 0.5MPa, while the profile barrel saves space in tight transfer chutes.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X1000S-08A the Right Choice?
Size by checking both neighbors: the 32mm bore pushes 402N at 0.5MPa, while the 63mm bore pushes 1559N. This 40mm bore fits applications needing around 628N push. Always confirm the AC220V terminal entry and PT threads match your control panel. The cylinder body rates to 1.0MPa, but you must size force within the 0.15-0.8MPa valve limit. The rod retracts when the coil energizes; reposition the valve to reverse this to extend-when-energized. Because the 1000mm stroke exceeds 300mm, use an external guide to prevent rod bending and side-load wear. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold loads safely.
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 SAUF40X1000S-08A FAQ
It uses a built-in 4M210-08 valve (1/4" port, Cv 0.89, 5 cycles/s) with an AC220V terminal coil. Force is 628N push and 528N pull at 0.5MPa. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
No, the built-in valve only routes air and is not a load lock. If air is lost, the piston drifts. For load holding, install an external rod lock or a pilot-operated check valve. The default action retracts the rod when energized, but you can reposition the valve to extend on signal.
