Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X150S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X150S-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 150mm 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 SAUF80X150S-08A
The SAUF80X150S-08A is a double-acting profile 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. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. It features a 3/8" cylinder port, an M20x1.5 rod thread, and 28mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa range, it delivers 2513 N push force at 0.5 MPa. The 1/4" valve port provides 25 mm2 flow (Cv 1.4) at up to 4 cycles/sec. The AC220V terminal coil is IP65 rated. Based on the 0.5 MPa push force, the safe working load is about 1508 N, allowing a 128 kg vertical lift with a 2:1 margin. The -S suffix denotes a piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF80X150S-08A Is Used
Package Divert Gate
Uses one coil signal to actuate a heavy divert arm directly at the conveyor lane, skipping long tube runs back to a central manifold.
Pallet Stopper Unit
Deploys a robust stop block on a packaging line. The integrated valve ensures immediate local response without needing a remote valve island.
Press Ejection Arm
Cycles at up to 4 Hz to eject parts from a machine bed. The built-in 4M310 valve handles the 2513 N push force efficiently.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X150S-08A the Right Choice?
Size by checking both neighboring bores: the 63mm bore offers 1559 N push at 0.5 MPa, while the 100mm bore provides 3927 N. This 80mm bore yields 2513 N push and 2268 N pull at 0.5 MPa. Confirm the AC220V terminal entry and PT threads match your supply. The cylinder body rates to 1.0 MPa, but you must size force within the built-in valve's 0.15-0.8 MPa window. The rod retracts when energized; reposition the valve to reverse this. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold loads. For this 150mm stroke, ensure side-load guidance.
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 SAUF80X150S-08A FAQ
It delivers 2513 N push and 2268 N pull at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow) running on AC220V. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate in the 0.15-0.8 MPa valve window.
No. The built-in 5/2 valve only routes air; it is not a locking device. If air is lost, the piston drifts. Install an external rod lock or pilot-operated check valve for secure load holding.
