Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700-08A 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 SAUF40X700-08A
The AirTAC SAUF40X700-08A is a double-acting profile cylinder with a built-in 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 cylinder of the same bore. This SKU uses terminal entry with PT threads and has no magnet, so it cannot accept a magnetic switch.
It delivers 628 N push at 0.5 MPa, sized within the valve's 0.15-0.8 MPa operating window. The 1/4" valve port yields a 16 mm2 flow (Cv 0.89) with a 5 cycle/s limit. For sizing, the safe working load is roughly 377 N (about 60% of the 0.5 MPa push), and vertical lift capacity is about 32 kg with a 2:1 margin. The cylinder body rates to 1.0 MPa, but the assembled unit is capped by the valve at 0.8 MPa.

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 SAUF40X700-08A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate to push packages. One AC220V coil signal actuates the 700 mm stroke without running long tubing back to a central manifold.
Remote Machine Guard Gate
Operates a safety gate far from the control cabinet. The built-in 4M210-08 valve routes air locally, saving manifold space and simplifying installation.
Long-Stroke Pallet Stop
Deploys a 700 mm stop arm on a pallet line. The profile cylinder provides compact mounting while the integrated valve ensures fast 5 cycle/s response.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X700-08A the Right Choice?
Size by checking both neighboring bores: the 32 mm bore yields 402 N push while the 50 mm bore yields 982 N push at 0.5 MPa. Confirm this AC220V terminal entry coil matches your supply. Default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Because the 700 mm stroke is long, use an external guide to prevent rod bending and side loads. The valve only routes air; it is not a lock. Add an external rod lock or pilot-operated check valve to hold a load securely.
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 SAUF40X700-08A FAQ
It provides 628 N push and 528 N pull at 0.5 MPa, reaching 1005 N push at 0.8 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s max) running on AC220V. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly within the 0.15-0.8 MPa valve window. The bore's air port is 1/4".
Yes. The default action retracts the rod when the coil is energized. You can reconfigure it to extend-when-energized simply by repositioning the built-in valve. This decentralized setup means one coil signal drives the cylinder directly, with no remote valve needed.
