Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450S-08A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 450mm 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 SAUF80X450S-08A
The SAUF80X450S-08A is a double-acting profile-type cylinder with a built-in AirTAC 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 makes it shorter than an ISO 15552 cylinder of the same bore. It includes a piston magnet for CMSG/DMSG/EMSG switches.
The 80mm bore delivers 2513N push at 0.5MPa within the valve's 0.15-0.8MPa working window. The integrated 4M310-08 valve has a 1/4" port, Cv 1.4, and runs up to 4 cycles/sec. The coil is AC220V with terminal entry. Computed buyer insight: safe working load is roughly 1508N (60% of the 0.5MPa push), yielding a 128kg vertical lift with a 2:1 margin. The cylinder port is 3/8".

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 SAUF80X450S-08A Is Used
Decentralized Conveyor Diverter
Mounts directly at the divert station. One AC220V signal actuates the 4M310 valve, pushing packages without running air lines back to a central manifold.
Independent Stacking Gate
Ideal for isolated pallet stops. The built-in valve handles 4 cycles/sec, and the 450mm stroke accommodates varying pallet widths without extra plumbing.
Remote Machine Guard
Deployed on distant safety doors. The IP65 coil and terminal entry provide reliable switching, saving manifold slots on the main control panel.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X450S-08A the Right Choice?
Size between neighbours: the 63mm bore gives 1559N push at 0.5MPa, while the 100mm bore gives 3927N. This 80mm bore yields 2513N push and 2268N pull at 0.5MPa, peaking at 4021N push at the 0.8MPa valve limit. Confirm the AC220V terminal entry and PT threads. Default action retracts the rod when energised; reposition the valve to extend-when-energised. The valve routes air and is not a load lock—add an external rod lock or pilot-operated check valve to hold a load. For the 450mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF80X450S-08A FAQ
It pushes 2513N and pulls 2268N at 0.5MPa, reaching 4021N push at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec) with an AC220V terminal-entry coil. Although the cylinder body rates to 1.0MPa, size force within the valve's 0.15-0.8MPa window. The cylinder port is 3/8".
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised by repositioning the valve. The 5/2 valve only routes air; it is not a load lock. On air loss the piston drifts, so add an external rod lock or pilot-operated check valve for suspended loads.
