Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450-08A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 450mm 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 SAUF40X450-08A
The SAUF40X450-08A 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 cylinder of the same bore. This 40mm bore unit pushes 628N at 0.5MPa, operating within the 0.15-0.8MPa valve window. The cylinder port is 1/4".
The integrated valve delivers a 16mm2 flow (Cv 0.89) at 1/4" and handles up to 5 cycles per second. It uses an AC220V terminal entry coil rated IP65. Based on the 628N push force at 0.5MPa, the safe working load is roughly 377N, yielding a vertical lift capacity of about 32kg with a 2:1 margin. Since this SKU lacks a magnet suffix, 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 SAUF40X450-08A Is Used
Diverter Gate Actuation
Drives a sorting diverter directly at the conveyor lane. The built-in 4M210 valve provides local switching without running long tubing back to a central manifold.
Decentralized Pallet Stop
Raises and lowers a pallet stop in a storage line. One AC220V signal operates the 40mm bore, saving manifold space while providing 628N push at 0.5MPa.
Independent Clamp Station
Powers a clamping mechanism on a remote machining cell. The integrated valve handles 5 cycles per second, ideal for isolated actuators requiring rapid action.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450-08A the Right Choice?
Size against the 32mm and 50mm bores: the 32mm bore yields 402N push at 0.5MPa, while the 50mm bore yields 982N. This 40mm bore provides 628N push and 528N pull at 0.5MPa. Always size force within the 0.15-0.8MPa valve operating range, not the 1.0MPa cylinder body rating. The AC220V terminal entry coil is fixed. The rod retracts when energised, but you can reposition the valve to extend on signal. Without air, the valve routes air but does not lock the load—add an external rod lock or pilot-operated check valve for holding. At 450mm 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 SAUF40X450-08A FAQ
It generates 628N push and 528N pull at 0.5MPa. The built-in valve is a 4M210-08 (5/2 solenoid) with a 1/4" port, Cv 0.89, and 16mm2 flow. The AC220V terminal entry coil runs the assembled unit at 0.15-0.8MPa, despite the 1.0MPa cylinder body rating.
Yes. The default action retracts the rod when the coil is energised, but you can reconfigure it to extend by repositioning the valve. The valve only routes air; it does not lock the piston. For load holding on air loss, install an external rod lock or pilot-operated check valve.
