Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 225mm 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 SAUF40X225-08A
The AirTAC SAUF40X225-08A is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve on the cap. One AC220V 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. It features a 1/4" cylinder port, an M12x1.25 rod thread, and 21 mm adjustable cushions.
Operating strictly within the valve's 0.15-0.8 MPa window, this bore pushes 628 N and pulls 528 N at 0.5 MPa. The integrated valve provides a 16 mm2 flow (Cv 0.89) and handles up to 5 cycles per second. For sizing, the safe working load is roughly 377 N, and it can vertically lift about 32 kg with a 2:1 margin. This terminal-entry SKU lacks a magnet, so it cannot accept a magnetic 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 SAUF40X225-08A Is Used
Decentralized Clamping
Drives independent clamping fixtures directly at the point of operation, removing the need for a central valve manifold.
Inline Diverters
Powers sorting gates on a conveyor line using a single AC220V signal, cutting installation tubing and simplifying maintenance.
Independent Pick-Place
Handles small component transfer across multiple machine zones, where each actuator switches itself locally.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225-08A the Right Choice?
Size force between the 0.15-0.8 MPa valve limits: this 40 mm bore yields 628 N push at 0.5 MPa, whereas the adjacent 50 mm bore yields 982 N. Confirm the AC220V terminal entry meets your control voltage. Default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Because this SKU lacks a magnet, it cannot mount a sensor. The built-in valve routes air; it is not a lock, so add an external rod lock or pilot-operated check valve to hold a load. For this 225 mm stroke, guide the mechanism to manage side loads.
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 SAUF40X225-08A FAQ
It generates 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec max) running on AC220V terminal entry. Although the cylinder body rates to 1.0 MPa, size force within the assembled valve's 0.15-0.8 MPa operating window.
Yes. The default action retracts the rod on energisation, but you can reposition the valve to make it extend instead. The valve only routes air; it is not a lock. The rod will drift on air loss, so fit an external rod lock or pilot-operated check valve for load holding.
