Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X450-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X450-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 450mm stroke and a built-in 4M310-08 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 SAUF100X450-08B
The SAUF100X450-08B is a double-acting profile cylinder with a built-in AirTAC 4M310 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 100mm bore unit features a 1/2" cylinder port, a 25mm rod, and 29mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa window, it delivers a 3927 N push force at 0.5 MPa. The integrated 4M310-08 valve has a 1/4" port, Cv 1.4, and cycles up to 4 times per second. The DC24V terminal coil is IP65 rated. For sizing, the safe working load is roughly 2356 N, allowing a vertical lift of about 200 kg with a 2:1 margin. 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAUF100X450-08B Is Used
Heavy Press Station
Decentralized pressing in a large assembly line. The built-in valve provides immediate actuation without routing long tubing back to a central manifold.
Pallet Diverting
High-force lane switching for heavy pallets. One coil signal drives the 100mm bore directly at the diverting point, simplifying installation.
Vertical Lift Gate
Lifting a 200kg materials gate. The integrated 4M310 valve handles the airflow locally, saving manifold space on the control panel.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X450-08B the Right Choice?
Size by comparing neighboring bores: the 80mm bore pushes 2513 N while this 100mm bore pushes 3927 N at 0.5 MPa. Confirm the DC24V terminal coil and PT thread suit your control system. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The 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 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 SAUF100X450-08B FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec) with a DC24V terminal coil. Size the force within the valve's 0.15-0.8 MPa operating window; do not use the 1.0 MPa cylinder body rating for the assembled unit.
No. The built-in 5/2 valve routes air but is not a load lock. On air loss the piston drifts, and the 29mm cushion only decelerates near stroke end. Install an external rod lock or pilot-operated check valve to hold a load. Also, since this SKU lacks a magnet, it cannot accept a sensor.
