Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X100-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X100-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 100mm 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 SAUF100X100-08B
The SAUF100X100-08B 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 unit of the same bore. This 100mm bore pushes 3927N and pulls 3681N at 0.5MPa, operating via a 1/2" cylinder port and an M20x1.5 rod thread.
The integrated valve features a 1/4" port with 25mm2 flow (Cv 1.4) and switches up to 4 cycles per second. The DC24V terminal coil offers IP65 protection and a 0.05s response. Size force within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder body rating. 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 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 SAUF100X100-08B Is Used
Machine Tool Clamping
Decentralized clamping on large CNC fixtures where running a 100mm bore back to a central manifold wastes tubing and cycle time.
Heavy Diverter Gate
Actuating a high-force routing gate directly at the lane, using the built-in 4M310 valve to switch locally without extra plumbing.
Pallet Stopper Arm
Independent stopper arms on multiple conveyor zones, each driven by one DC24V signal to simplify controls and eliminate valve islands.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X100-08B the Right Choice?
When sizing, compare this 100mm bore (3927N push at 0.5MPa) against the 80mm neighbor (2513N) to ensure adequate force. The 100mm stroke is above the 75mm SAUF minimum for this bore. Confirm the DC24V terminal coil and PT thread match your supply. The rod retracts by default when energized; reposition the valve to extend on signal. Because the 4M310 valve routes air rather than locking it, add an external rod lock or pilot-operated check valve for load holding on air loss. For any stroke at or above 300mm, use side-load guides to prevent rod damage.
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 SAUF100X100-08B FAQ
It delivers 3927N push and 3681N pull at 0.5MPa, reaching 6282N at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4 cycles/sec max) with a DC24V terminal coil. You must size force within the 0.15-0.8MPa valve operating window, even though the cylinder body rates to 1.0MPa.
This specific SKU lacks the -S magnet option, so it cannot accept a magnetic switch. Additionally, the built-in 5/2 valve routes air but does not lock the piston; on air loss the load drifts. Install an external rod lock or pilot-operated check valve if you need to hold a load.
