Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 450mm 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 SAUF50X450-06A
The SAUF50X450-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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 cylinder of the same bore. This 50mm bore uses a 1/4" cylinder port, a 1/8" valve port, and a Ø20mm rod with an M16x1.5 thread.
Operating within the valve's 0.15-0.8 MPa window, it delivers 982N push and 825N pull at 0.5MPa. The integrated valve flows 14mm2 (Cv 0.78) at up to 5 cycles per second. For sizing, the safe working load is roughly 589N, and it can vertically lift about 50kg with a 2:1 margin. Because this 450mm stroke exceeds 300mm, add external guides to prevent rod bending. 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAUF50X450-06A Is Used
Conveyor Diverter Gate
A single electrical signal actuates this diverter directly at the conveyor lane, removing the need to run long pneumatic tubes back to a central manifold.
Decentralized Pallet Stop
Mounts independently on a pallet line. The integrated 4M210-06 valve switches the 450mm stroke locally, saving manifold space and simplifying plumbing.
Component Pusher Station
Pushes parts between machine zones. The self-contained AC220V valve handles the 5 cycles per second demand without burdening a main valve island.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450-06A the Right Choice?
When sizing, compare neighbouring bores: a 40mm bore gives 628N push while a 63mm bore provides 1559N at 0.5MPa. This 50mm bore outputs 982N push and 825N pull at 0.5MPa. Confirm your coil is AC220V with terminal entry before ordering. The cylinder body rates to 1.0MPa, but you must size force within the built-in valve's 0.15-0.8MPa operating range. By default the rod retracts when the coil is energised, but you can reconfigure it to extend by repositioning the valve. The 450mm stroke requires external guides to manage side-load and rod-bending forces. The valve only routes air, so for load holding on air loss add an external rod lock or pilot-operated check valve. This SKU has no magnet and cannot take a sensor.
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 SAUF50X450-06A FAQ
It pushes 982N and pulls 825N at 0.5MPa. The built-in valve is a 4M210-06 (5/2 solenoid) with 1/8" ports, Cv 0.78, and runs up to 5 cycles/sec. The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0MPa, the assembled unit must operate in the 0.15-0.8MPa valve window.
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve on the cap. This self-contained switching means you only run one electrical signal to the cylinder, completely eliminating the need for a separate remote valve.
