Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X1000S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X1000S-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 1000mm 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 SAUF80X1000S-08B
The SAUF80X1000S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One DC24V 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 80mm bore pushes 2513N at 0.5MPa, scaling to 4021N at the 0.8MPa assembled maximum. The cylinder port is 3/8" and the valve port is 1/4".
The integrated valve flows 25mm2 (Cv 1.4) at up to 4 cycles per second. Because the valve routes air, it is not a load lock. For sizing, a safe working load is roughly 1508N (60% of the 0.5MPa push force), translating to a vertical lift capacity of about 128kg with a 2:1 margin. The piston magnet supports CMSG/DMSG/EMSG switches, and the 1000mm stroke requires external guiding to prevent rod bending.

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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 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 SAUF80X1000S-08B Is Used
Decentralized Conveyor Divert
Mounts directly on the line for one-signal diverting. The integrated 4M310-08 valve eliminates long tube runs back to a central manifold, improving cycle response.
Vertical Lift Gate
Provides a safe 128kg vertical lift capacity with a 2:1 margin at 0.5MPa. The built-in piston magnet allows precise end-of-stroke detection via CMSG switches.
Long-Stroke Material Pusher
Drives heavy workpieces over 1000mm. The compact profile barrel saves space, while the self-contained DC24V valve simplifies electrical wiring across large machine layouts.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X1000S-08B the Right Choice?
Size force between 0.15 and 0.8 MPa: this 80mm bore yields 2513N push at 0.5MPa, while the neighboring 63mm bore yields 1559N and the 100mm bore yields 3927N under the same pressure. Confirm the DC24V terminal entry and PT threads match your control scheme. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. The valve only routes air, so add an external rod lock or pilot-operated check valve for load holding. Because the 1000mm stroke exceeds 300mm, use external guides to manage side-load and rod-bending forces.
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 SAUF80X1000S-08B FAQ
It generates 2513N push and 2268N pull at 0.5MPa, reaching 4021N at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25mm2 flow) running on a DC24V terminal-entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
No. The built-in 5/2 valve only routes air; it is not a locking mechanism. If air is lost or the valve is centered, the piston will drift. To maintain a vertical or suspended load, you must install an external rod lock or a pilot-operated check valve.
