Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X225-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X225-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 225mm 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 SAUF100X225-08B
The AirTAC SAUF100X225-08B is a double-acting profile cylinder with a built-in 4M 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 pushes 3927N and pulls 3681N at 0.5MPa, operating within the 0.15-0.8MPa valve window.
It uses a 4M310-08 valve with a 1/4" port, delivering 25mm2 flow (Cv 1.4) at up to 4 cycles per second. The DC24V terminal coil offers IP65 protection. The cylinder body rates to 1.0MPa, but the assembled unit operates at 0.15-0.8MPa. Based on the 0.5MPa push force, the safe working load is roughly 2356N, capable of a 200kg vertical lift with a 2:1 margin. The 1/2" cylinder port and M20x1.5 rod thread handle high flow.

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 SAUF100X225-08B Is Used
Decentralized Press Clamps
Ideal for large presses needing individual clamping. The integrated 4M310-08 valve switches the 100mm bore directly, saving manifold space and tubing.
Heavy Diverter Arms
Provides robust diverting force on high-mass conveyors. One DC24V signal actuates the arm without routing a separate valve line across the frame.
Pallet Lift Stations
Handles vertical lifting in automated palletizers. The 1/2" cylinder port supports the high air flow needed for rapid 100mm bore motion.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X225-08B the Right Choice?
When sizing, compare neighboring bores: the 80mm bore pushes 2513N while the 100mm bore pushes 3927N at 0.5MPa. This model uses a DC24V terminal entry coil. The rod retracts when energized by default, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 225mm stroke, ensure adequate side-load guidance using SC-series mounts.
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 SAUF100X225-08B FAQ
It delivers 3927N push and 3681N pull at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4) running on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the 0.15-0.8MPa valve window.
No remote valve is needed; the integrated 5/2 valve switches the cylinder directly. However, the valve only routes air and is not a load lock. For vertical loads that must be held on air loss, install an external rod lock or pilot-operated check valve.
