Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450-08B 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 SAUF50X450-08B
The SAUF50X450-08B is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than a standard ISO 15552 unit of the same bore. This bore uses a 1/4" cylinder port, an M16x1.5 rod thread, and adjustable 21 mm cushions.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 982 N push force at 0.5 MPa. This yields a safe working load of roughly 589 N, or a 50 kg vertical lift with a 2:1 margin. The 1/4" valve port provides 16 mm2 flow (Cv 0.89) at up to 5 cycles per second. Because this SKU lacks the S 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 (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 SAUF50X450-08B Is Used
Diverter Gate Actuation
Drives a routing flap on a conveyor line directly from one coil signal, removing the need to run tubing back to a central manifold.
Decentralized Pallet Stop
Raises and lowers a pallet stop in a packaging cell, saving manifold space while providing 982 N of push force at 0.5 MPa.
Independent Clamp Station
Powers a clamping fixture on a large machine bed without extra plumbing, utilizing the integrated 4M210-08 valve.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450-08B the Right Choice?
Size force between the 50 mm bore (982 N push at 0.5 MPa) and the 63 mm bore (1559 N) based on your load. Verify the DC24V terminal entry and PT threads. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size within the 0.15-0.8 MPa valve limit, not the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a load lock; 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 SAUF50X450-08B FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (Cv 0.89, 16 mm2 flow) running on DC24V. You must size loads within the 0.15-0.8 MPa valve operating window. The cylinder port is 1/4" and the rod thread is M16x1.5.
No. The built-in valve only routes air; it is not a lock. The rod drifts on air loss. For load holding, install an external rod lock or pilot-operated check valve. Also, note this SKU lacks a magnet and cannot take a sensor.
