Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900-10B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 900mm stroke and a built-in 4M310-10 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 SAUF80X900-10B
The AirTAC SAUF80X900-10B is a double-acting profile cylinder with a built-in 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. This 80mm bore uses a Ø25mm rod, M20x1.5 rod thread, and a 3/8" cylinder port.
Size force within the valve's 0.15-0.8 MPa window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it pushes 2513N and pulls 2268N. The safe working load is roughly 1508N, allowing a vertical lift of about 128kg with a 2:1 margin. The 4M310-10 valve delivers a 3/8" port, Cv 1.68 flow, and 4 cycles/s. It uses a DC24V terminal entry coil rated IP65. Without a -S suffix, this SKU cannot take a magnetic switch.

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 SAUF80X900-10B Is Used
Decentralized Conveyor Divert
Mounts directly on a conveyor diverter arm. The integrated DC24V valve switches the 900mm stroke locally, eliminating long tube runs back to a central manifold.
Large Carton Pusher
Pushes heavy packaging lines using the 2513N push force at 0.5 MPa. The built-in 4M310 valve handles the airflow, saving manifold space in tight control panels.
Automated Machine Gate
Actuates a large machine safety gate. The profile cylinder provides compact installation while the single coil signal simplifies wiring for decentralized automation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900-10B the Right Choice?
When sizing, compare neighbouring bores: the 63mm bore yields 1559N push at 0.5 MPa, while the 100mm bore yields 3927N. This 80mm bore provides 2513N push at 0.5 MPa. Confirm the DC24V terminal entry and PT thread suit your control system. The valve runs at 0.15-0.8 MPa, so never size the assembled unit at the 1.0 MPa cylinder body rating. The default action retracts the rod when energised, but repositioning the valve extends it on signal. The 900mm stroke requires an external guide to prevent rod bending and side-load wear. The valve routes air and is not a lock; 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 SAUF80X900-10B FAQ
It pushes 2513N and pulls 2268N at 0.5 MPa, reaching 4021N at 0.8 MPa. The built-in valve is a 4M310-10 with a 3/8" port and Cv 1.68. The DC24V coil operates at 0.15-0.8 MPa; do not exceed 0.8 MPa despite the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod on signal, but you can reposition the built-in valve to extend the rod when energised. This self-switching design means no remote valve is needed, though the valve only routes air and does not lock the load.
