Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X800S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X800S-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 SAUF100X800S-08B
The SAUF100X800S-08B is a double-acting profile cylinder featuring an integrated 4M310 5/2 solenoid valve directly on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot in large decentralized machinery. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. It includes a piston magnet for CMSG/DMSG/EMSG switches.
This 100mm bore delivers 3927N push force at 0.5MPa, scaling to 6282N at the 0.8MPa assembled maximum. The integrated valve provides 25mm2 flow (Cv 1.4) via a 1/4" port, cycling up to 4 times per second. For sizing, the safe working load is roughly 2356N (about 60% of the 0.5MPa push), yielding a 200kg vertical lift capacity with a 2:1 margin. The cylinder body rates to 1.0MPa, but the valve limits operation to 0.15-0.8MPa.

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 SAUF100X800S-08B Is Used
Decentralized Press Clamping
Uses the integrated 4M310 valve to clamp heavy workpieces directly at the press station, eliminating long tubing runs back to a central manifold.
Inline Divert Gate
Actuates a large divert gate along a high-speed conveyor. The built-in DC24V coil provides rapid 4 cycle/sec shifting without a remote valve bank.
Pallet Lift Station
Lifts pallets vertically in an automated storage system. The 100mm bore provides 3927N push at 0.5MPa, easily handling 200kg loads with a 2:1 margin.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X800S-08B the Right Choice?
When sizing, compare neighboring bores: the 80mm bore offers 2513N push at 0.5MPa, while this 100mm bore provides 3927N. Confirm the DC24V terminal entry and PT thread meet your control specs. The default action retracts the rod when the coil is energized, but you can reposition the valve to extend on energization. Always size force within the 0.15-0.8MPa valve window, never the 1.0MPa cylinder body rating. Because the 800mm stroke exceeds 300mm, use 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 loads 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 SAUF100X800S-08B FAQ
It generates 3927N push and 3681N pull at 0.5MPa, reaching 6282N push at 0.8MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port, Cv 1.4, and 25mm2 flow. The coil is DC24V with terminal entry. Although the cylinder body rates to 1.0MPa, the integrated valve restricts the working pressure to 0.15-0.8MPa.
No. The built-in valve only routes air; it does not lock the piston. If air is lost, the rod will drift. You must add an external rod lock or a pilot-operated check valve to hold a load safely. The default action retracts the rod when energized, but you can reposition the valve to extend on energization.
