Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 250mm 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 SAUF100X250-08B
The SAUF100X250-08B 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. It has a 100mm bore, 250mm stroke, 1/2" cylinder port, and an M20x1.5 rod thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 3927N push force at 0.5MPa. The integrated 4M310-08 valve has a 1/4" port, Cv 1.4, and runs up to 4 cycles/sec. The DC24V coil offers IP65 protection with terminal entry. 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. Note this SKU lacks the S suffix, so it cannot take a magnetic 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 SAUF100X250-08B Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center. The built-in 4M310 valve switches this 100mm bore directly, saving manifold space and tubing runs.
Heavy Diverter Gate
Actuating a heavy diverter on a packaging line. One DC24V signal drives the 3927N push force without routing a separate remote valve back to a central island.
Pallet Stopper Arm
Controlling pallet flow in a high-cycle warehouse. The integrated valve handles 4 cycles/sec, and the compact profile fits tight conveyor frames.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250-08B the Right Choice?
Size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. At 0.5MPa this 100mm bore pushes 3927N and pulls 3681N; the neighboring 80mm bore pushes 2513N. Confirm the DC24V terminal entry and PT threads meet your control specs. The rod retracts when energized by default, but you can reposition the valve to extend on signal. Because the 250mm stroke is under 300mm, side-load guides are less critical, but always guide the load. The valve only routes air; it is not a lock. For load holding on air loss, add an external rod lock or pilot-operated check valve. This non-S model cannot accept magnetic switches.
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 SAUF100X250-08B FAQ
It pushes 3927N and pulls 3681N at 0.5MPa, sizing within the 0.15-0.8 MPa valve window. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec). The coil is DC24V with terminal entry. The cylinder body rates to 1.0 MPa, but the assembled unit must operate at 0.15-0.8 MPa.
By default, the rod retracts when the coil is energized; you can reposition the valve to extend on signal. The 5/2 valve routes air but does not lock the piston. If air drops, the load drifts. For holding, install an external rod lock or pilot-operated check valve.
