Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X160-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X160-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 160mm 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 SAUF80X160-08A
The SAUF80X160-08A is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. It is shorter than an ISO 15552 cylinder of the same bore and mounts with AirTAC SC-series accessories. The bore dictates a 3/8" cylinder port and an M20x1.5 rod thread.
Operating strictly within the 0.15-0.8 MPa valve window, it generates 2513 N push force at 0.5 MPa. This yields a safe working load of roughly 1508 N, or a 128 kg vertical lift with a 2:1 margin. The integrated valve flows 25 mm2 (Cv 1.4) via a 1/4" port, cycling up to 4 times per second. The AC220V terminal-entry coil is IP65 rated. Since this SKU lacks the -S suffix, it cannot accept a magnetic 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 SAUF80X160-08A Is Used
Transfer Line Diverter
Mounts directly on a conveyor diverter arm. The built-in valve removes long tube runs back to a central manifold, keeping cycle times fast.
Pallet Stop Gate
Ideal for decentralized pallet handling stops. One AC220V signal actuates the gate, saving manifold space and simplifying machine wiring.
Press Ejection Unit
Ejects parts from a press bed. The integrated 4M310 valve delivers high flow for rapid ejection without needing a separate remote valve bank.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X160-08A the Right Choice?
When sizing, compare both directions against neighboring bores: the 63mm bore yields 1559 N push at 0.5 MPa, while the 100mm bore reaches 3927 N. This 80mm bore provides 2513 N push and 2268 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa valve operating range, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry meets your supply. The rod retracts by default when energized; you can reconfigure it to extend by repositioning the valve. Because the 160mm stroke exceeds 300mm, ensure external side-load guidance. The valve only routes air, so add an external rod lock or pilot-operated check valve for load holding.
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 SAUF80X160-08A FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa, reaching 4021 N at 0.8 MPa. Size within the 0.15-0.8 MPa valve window. The built-in 4M310-08 valve has a 1/4" port, Cv 1.4, and runs an AC220V terminal-entry coil.
No. The built-in valve routes air but does not lock the piston. If air is lost, the load drifts. For vertical load holding, add an external rod lock or pilot-operated check valve.
