Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 900mm 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 SAUF80X900-08A
The SAUF80X900-08A is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M310 5/2 solenoid valve on the cap. One coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The 80mm bore uses a 3/8" cylinder port and a 1/4" valve port. This compact profile is shorter than an ISO 15552 cylinder of the same bore.
Operating within the 0.15-0.8 MPa valve window, it delivers 2513N push at 0.5 MPa and 4021N at 0.8 MPa. The integrated valve flows 25 mm2 (Cv 1.4) at up to 4 cycles/sec. Computed buyer insight: safe working load is about 1508N (60% of the 0.5MPa push), yielding a 128kg vertical lift with a 2:1 margin. This terminal-entry AC220V SKU has no magnet and cannot accept a 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 (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 SAUF80X900-08A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a long conveyor line. One AC220V signal actuates the 80mm bore to push cartons, eliminating tubing runs back to a central manifold.
Palletizer Pusher Unit
Acts as a standalone pusher on a large palletizer. The built-in 4M310 valve handles the 900mm extend stroke independently, saving valve island space on the main frame.
Machine Guard Gate
Drives a 900mm safety guard on a large machine cell. The integrated valve ensures immediate local response without delayed air travel from a remote valve bank.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900-08A the Right Choice?
Size force between the 0.15-0.8 MPa valve limits, not the 1.0 MPa cylinder body rating. At 0.5 MPa this 80mm bore yields 2513N push and 2268N pull; the neighbouring 63mm bore gives 1559N push, and the 100mm bore gives 3927N push. Confirm the AC220V terminal entry and PT thread. Default action retracts the rod when energised; reposition the valve to extend on energise. Because this is a 900mm stroke, support the load with external guides to prevent rod bending and side-load wear. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. Without a -S suffix, this SKU cannot take a magnetic switch.
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 SAUF80X900-08A FAQ
It pushes 2513N and pulls 2268N at 0.5 MPa, reaching 4021N push at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4 cycles/sec max) running on AC220V terminal entry. Size the force within the 0.15-0.8 MPa valve operating window, as the assembled unit cannot use the 1.0 MPa cylinder body rating.
No remote valve is needed; the integrated 5/2 valve switches the cylinder from one coil signal. The valve only routes air, so it cannot hold a load on air loss. For vertical load holding, install an external rod lock or pilot-operated check valve, as the 28mm adjustable cushion only decelerates near stroke end.
