Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225-06A 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 SAUF40X225-06A
The SAUF40X225-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum body is shorter than an ISO 15552 unit of the same bore. This 40mm bore uses a 1/4" cylinder port and a 1/8" valve port.
Operating strictly within the valve's 0.15-0.8 MPa window, it generates 628N push and 528N pull at 0.5 MPa. The integrated 4M210-06 valve flows 14 mm2 (Cv 0.78) at up to 5 cycles/sec. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 377N (about 60% of the 0.5 MPa push force), translating to a vertical lift capacity of approximately 32kg with a 2:1 margin. Note this SKU lacks a magnet and cannot accept a 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 SAUF40X225-06A Is Used
Inline Diverter Gate
Uses the built-in valve to actuate a sorting flap directly on the conveyor frame without routing air lines back to a central manifold.
Decentralized Pallet Stop
Deploys a physical stop pin at a packing cell. The integrated 4M210 valve switches locally, saving manifold space and tubing.
Independent Clamp Station
Clamps parts at a standalone machining cell. One AC220V signal drives the clamp, simplifying installation on large machines.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225-06A the Right Choice?
When sizing, compare neighbouring bores: a 32mm bore yields 402N push at 0.5 MPa, while a 50mm bore yields 982N. This 40mm bore provides 628N push, making it ideal for medium loads. Always confirm the AC220V terminal entry coil matches your supply. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Remember the cylinder body rates to 1.0 MPa, but the assembled unit must operate at 0.15-0.8 MPa. The valve only routes air; it is not a lock, so add an external rod lock or pilot-operated check valve if you need to hold a load. For this 225mm stroke, ensure adequate side-load guidance.
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 SAUF40X225-06A FAQ
It generates 628N push and 528N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) driven by an AC220V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
No, the 5/2 valve only routes air and is not a lock; the piston will drift on air loss, so use an external rod lock or pilot-operated check valve for holding. Additionally, this specific SKU lacks a magnet (-S) and cannot accept a magnetic sensor.
