Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 225mm stroke and a built-in 4M210-06 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 SAUF40X225-06B
The SAUF40X225-06B is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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. It features a 1/4" cylinder port, an M12x1.25 rod thread, and 21mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa window, it delivers 628 N push and 528 N pull at 0.5 MPa. The 1/8" valve port yields a 14 mm2 flow (Cv 0.78) with a 5 cycle/s limit. The DC24V terminal coil offers IP65 protection and a 0.05 s response. For sizing, expect a safe working load around 377 N, or a vertical lift capacity near 32 kg with a 2:1 margin. This SKU lacks a magnet, so it cannot accept a magnetic switch.

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 SAUF40X225-06B Is Used
Inline Diverter Gate
Switches a routing flap directly on the conveyor frame using one DC24V signal, avoiding long tube runs back to a central manifold.
Compact Clamping Station
Provides 628 N of clamping force in a tight cell, using the integrated 4M210 valve to cycle at up to 5 Hz without extra plumbing.
Modular Test Fixture
Acts as a standalone actuator on a test bench, where the self-contained air routing simplifies setup and the 1/4" cylinder port matches standard fittings.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225-06B the Right Choice?
Size against the 0.5 MPa figures: this 40mm bore gives 628 N push, sitting between the 32mm (402 N) and 50mm (982 N) options. If your load needs more force, step up to the 50mm bore. Confirm the DC24V terminal coil and PT thread match your supply. The rod retracts when energised by default, but you can reconfigure it to extend by repositioning the valve. Because the built-in valve routes air rather than locking it, add an external rod lock or pilot-operated check valve to hold a load safely. For this 225mm stroke, ensure adequate side-load guidance. Remember the assembled unit operates at 0.15-0.8 MPa, not the 1.0 MPa cylinder body rating.
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 SAUF40X225-06B FAQ
It delivers 628 N push and 528 N pull at 0.5 MPa, powered by a built-in 4M210-06 valve with a 1/8" port, Cv 0.78, and a 5 cycle/s limit. The DC24V terminal coil is IP65 rated. You must size the force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
By default the rod retracts when the coil is energised, but you can reconfigure it to extend by repositioning the valve. The valve only routes air, so it cannot hold a load on air loss; you must add an external rod lock or pilot-operated check valve for secure load holding.
