Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250S-08A 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 SAUF100X250S-08A
The SAUF100X250S-08A 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. The 1/2" cylinder port and M20x1.5 rod thread handle high flow, while the 29mm adjustable cushions decelerate the rod near stroke ends.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 3927 N push at 0.5 MPa. The AC220V terminal coil offers IP65 protection and a 0.05s response. The integrated 4M310-08 valve features a 1/4" port, Cv 1.4 flow, and 4 cycles/s. For sizing, a safe working load is roughly 2356 N, allowing a vertical lift of about 200 kg 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)

|---|---|---|
| 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 SAUF100X250S-08A Is Used
Heavy Press Clamping
Decentralized clamping on large machining centers where the integrated valve provides immediate high-force actuation without long tubing runs from a central manifold.
Pallet Diverting
Independent diverting arms on packaging lines benefit from the one-signal operation, removing the need to plumb each station back to a main valve island.
Vertical Material Gates
High-thrust lifting gates in automated storage systems use the built-in 4M310 valve to cycle reliably, saving manifold slots and simplifying machine wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X250S-08A the Right Choice?
Size against the 63mm and 80mm neighbors: this 100mm bore provides 3927 N push at 0.5 MPa versus 2513 N for the 80mm. Verify the AC220V terminal entry matches your control voltage. The rod retracts by default when energized; reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve limit, never the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load safely. For this 250mm stroke, ensure external side-load guidance to prevent rod binding.
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 SAUF100X250S-08A FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa, reaching 6282 N push at 0.8 MPa. The built-in 4M310-08 valve has a 1/4" port, Cv 1.4, and runs on AC220V. You must size force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod when energized, but you can reposition the integrated 4M 5/2 valve to make it extend on signal. This decentralized switching means one coil signal drives the actuator directly, with no remote valve required.
