Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500S-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500S-10A is a genuine double-acting profile-type cylinder with a Ø80mm bore, 500mm 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 SAUF80X500S-10A
The SAUF80X500S-10A is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M310-10 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 80mm bore delivers 2513N push at 0.5MPa, operating safely within the valve's 0.15-0.8MPa window.
This unit features a 3/8" valve port with 30mm2 flow (Cv 1.68) and a 3/8" cylinder port. The AC220V terminal entry coil is IP65 rated. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG sensors. Based on the 2513N push at 0.5MPa, the safe working load is approximately 1508N, yielding a vertical lift capacity of about 128kg with a 2:1 margin.

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 SAUF80X500S-10A Is Used
Divert Gate Actuation
Drives a heavy diverting gate directly at the conveyor lane using one AC220V signal, skipping the main valve manifold.
Pallet Stopper Control
Raises and lowers a 128kg pallet stop independently, relying on the built-in 4M310-10 valve for localized routing.
Long-Stroke Press Ejection
Ejects parts from a press over a 500mm distance, using adjustable 28mm cushions to decelerate the payload smoothly.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X500S-10A the Right Choice?
When sizing, compare neighboring bores: the 63mm bore provides 1559N push while the 100mm bore yields 3927N push at 0.5MPa. This 80mm bore provides 2513N push and 2268N pull at 0.5MPa. Always size force within the 0.15-0.8MPa valve operating range, never the 1.0MPa cylinder body rating. Confirm the AC220V terminal entry coil meets your supply. The rod retracts when energized by default but can be reconfigured to extend by repositioning the valve. For this 500mm stroke, use external guides to prevent rod bending and side-load damage. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads securely.
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 SAUF80X500S-10A FAQ
It generates 2513N push and 2268N pull at 0.5MPa, reaching 4021N push at 0.8MPa. The built-in valve is a 4M310-10 5/2 solenoid with a 3/8" port, Cv 1.68, and a 4 cycles/s max frequency. It uses an AC220V terminal entry coil. The cylinder body rates to 1.0MPa, but you must size force within the valve's 0.15-0.8MPa operating window.
By default the rod retracts when energized, but you can reconfigure it to extend by repositioning the valve. The 5/2 valve only routes air; it is not a load lock. The piston will drift on air loss, so you must add an external rod lock or pilot-operated check valve for load holding.
