Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450-08A is a genuine double-acting profile-type cylinder with a Ø50mm 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 SAUF50X450-08A
The SAUF50X450-08A 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 makes it shorter than an ISO 15552 cylinder of the same bore. This SKU lacks a magnet, so it cannot take a magnetic switch.
It delivers 982 N push and 825 N pull at 0.5 MPa. The safe working load is roughly 589 N, and it can vertically lift about 50 kg with a 2:1 margin. The integrated valve has a 1/4" port, 16 mm2 flow (Cv 0.89), and handles 5 cycles per second. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window. The bore's air port is 1/4" with a PT thread, and it uses PU tube Ø8xØ5.

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 SAUF50X450-08A Is Used
Diverter Gate Actuation
Drives a sorting flap directly at the lane, using the built-in valve to switch instantly without running long tubing back to a central manifold.
Decentralized Pallet Stop
Raises and lowers a pallet stop in a large storage line, saving manifold slots and simplifying installation across multiple zones.
Inline Carton Sealing
Cycles a sealing head on demand, with the integrated 4M210 valve ensuring rapid local response without complex remote plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450-08A the Right Choice?
When sizing, compare both directions against neighbouring bores: a 40 mm bore gives 628 N push while a 63 mm bore gives 1559 N at 0.5 MPa. This 50 mm bore yields 982 N push and 825 N pull. Confirm the AC220V terminal entry meets your control voltage. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Always operate within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body limit. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold a load. For this 450 mm stroke, use external guides to prevent rod bending and 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 SAUF50X450-08A FAQ
It provides 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) with an AC220V terminal entry 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.
By default, the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The valve only routes air; it is not a lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve for load holding.
