Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X600-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X600-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 600mm 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 SAUF40X600-08A
The SAUF40X600-08A 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 SKU uses terminal entry and has no magnet, so it cannot accept a position sensor.
Operating within the valve's 0.15-0.8 MPa range, this 40mm bore delivers 628N push and 528N pull at 0.5 MPa. The 1/4" valve port yields a 16 mm2 flow (Cv 0.89) and cycles up to 5 times per second. The cylinder port is 1/4". For sizing, the safe working load is roughly 377N, and vertical lift capacity is about 32kg 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 (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 SAUF40X600-08A Is Used
Divert Gate Actuation
Drives a decentralized diverting flap on a packaging line, switching itself locally to save manifold space and tubing runs.
Vertical Package Stopper
Raises and lowers a stopper blade on a gravity roller conveyor, utilizing the self-contained valve for rapid 5 cycle/sec response.
Machine Tool Guard
Operates a 600mm stroke safety guard door directly at the machine, requiring only a single AC220V signal to move.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X600-08A the Right Choice?
When sizing, compare neighboring bores: a 32mm bore offers 402N push while a 50mm bore provides 982N at 0.5 MPa. This 40mm unit delivers 628N push. Confirm the AC220V terminal coil and PT thread before ordering. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Size force strictly within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. For the 600mm 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 SAUF40X600-08A FAQ
It generates 628N push and 528N 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 valve's 0.15-0.8 MPa operating window.
Yes. The default action retracts the rod when energized, but you can reposition the built-in valve to make the rod extend on signal. Because this SKU lacks the -S magnet suffix, it cannot accept magnetic position switches.
