Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350S-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350S-10A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 350mm 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 SAUF80X350S-10A
The SAUF80X350S-10A is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M310 5-port 2-position solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 80mm bore uses a 3/8" air port, a Ø25mm rod with an M20x1.5 thread, and 28mm adjustable cushions. This unit includes a piston magnet (-S) for CMSG/DMSG/EMSG switches.
It pushes 2513N and pulls 2268N at 0.5MPa. The integrated 4M310-10 valve has a 3/8" port, Cv 1.68, and cycles up to 4 times per second. The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa window. Based on the 0.5MPa push force, the safe working load is roughly 1508N, capable of a 128kg vertical lift with a 2:1 margin. The AC220V terminal coil is IP65 rated.

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 SAUF80X350S-10A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate to eliminate long tubing runs back to a central manifold, using the 4M310 valve for immediate local switching.
Independent Pallet Stopper
Acts as a standalone pallet stop on a packing line, driven by one AC220V signal without consuming a slot on the main valve island.
Machine Tool Clamp
Provides localized clamping on a large machining center, saving installation time by integrating the 5/2 valve directly on the cylinder cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350S-10A the Right Choice?
Size against the 63mm and 100mm neighbors: the 63mm bore yields 1559N push at 0.5MPa, while the 100mm bore provides 3927N. This 80mm unit delivers 2513N push at 0.5MPa, reaching 4021N at the 0.8MPa valve maximum. Confirm the AC220V terminal entry and PT threads suit your control panel. The default action retracts the rod when the coil is energized; reposition the valve to extend on energization. Because the 350mm stroke exceeds 300mm, use an external guide to prevent rod bending and side-load wear. The integrated valve routes air but does not function as a load lock—add an external rod lock or pilot-operated check valve to hold a suspended load 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 SAUF80X350S-10A FAQ
It generates 2513N push and 2268N pull at 0.5MPa, maxing out at 4021N push at 0.8MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, 4 cycles/sec max). It uses an AC220V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa range.
Yes. The default action retracts the rod when energized, but you can reposition the valve to extend on energization. The valve only routes air; it is not a load lock. The piston will drift on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a load.
