Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X800-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X800-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 800mm 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 SAUF100X800-08B
The SAUF100X800-08B 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 makes it shorter than an ISO 15552 cylinder of the same bore. This 100mm bore pushes 3927N and pulls 3681N at 0.5MPa, operating within the valve's 0.15-0.8MPa window.
The integrated valve offers 1/4-inch porting, Cv 1.4 flow, and a 4 cycles/s limit. It uses a DC24V terminal coil rated IP65. The cylinder body rates to 1.0MPa but the assembled unit is capped at 0.8MPa. For sizing, the safe working load is roughly 2356N (60% of the 0.5MPa push), allowing a vertical lift of about 200kg with a 2:1 margin. This SKU lacks the S suffix for a magnet, so 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 (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 SAUF100X800-08B Is Used
Decentralized Press Clamps
Ideal for large press lines where running individual lines to a central manifold is impractical, switching each clamp directly with one DC24V signal.
Independent Diverters
Perfect for long conveyor sorting gates that need isolated actuation without dedicating a remote valve island slot for every single movement.
Vertical Lift Stations
Suitable for heavy material lift stations, providing up to 200kg vertical lift capacity with a 2:1 safety margin at 0.5MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X800-08B the Right Choice?
When sizing, compare neighboring bores: the 80mm bore yields 2513N push while the 100mm bore provides 3927N at 0.5MPa. Always size force within the 0.15-0.8MPa valve window, never the 1.0MPa cylinder body rating. Confirm the DC24V terminal entry and PT thread match your supply. The rod retracts when the coil is energized, but you can reposition the valve to extend on signal. Because the 800mm stroke exceeds 300mm, add external guides to prevent rod bending and side-load wear. The valve only routes air; it is not a lock, so add an external rod lock or pilot-operated check valve to hold a load safely.
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 SAUF100X800-08B FAQ
It pushes 3927N and pulls 3681N at 0.5MPa. The built-in valve is a 4M310-08 (1/4-inch port, Cv 1.4, max 4 cycles/s) with a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the 0.15-0.8MPa valve window. The bore's air port is 1/2-inch.
Yes, you can reconfigure the valve position to make the rod extend when the coil is energized. The valve routes air but does not lock the piston, so the load drifts on air loss. Add an external rod lock or pilot-operated check valve for secure holding.
