Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 350mm 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 SAUF80X350-08B
The SAUF80X350-08B is a double-acting profile 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 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 in the 0.15-0.8 MPa valve window, it delivers 2513 N push force at 0.5 MPa. The 1/4" valve port yields a Cv of 1.4 and cycles up to 4 times per second. The DC24V terminal coil is IP65 rated. For sizing, the safe working load is roughly 1508 N, and vertical lift capacity is about 128 kg 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 SAUF80X350-08B Is Used
Package Divert Gate
Decentralized sorting line actuator where the integrated valve switches the divert gate directly at the station without long tubing runs back to a central manifold.
Vertical Lift Stopper
Independent lifting stopper in a high-bay storage buffer. The built-in 4M310 valve provides fast local response for a 350mm stroke blocking mechanism.
Machine Tool Clamp
Single-actuator clamping station on a machining line. One DC24V coil signal controls the clamp, freeing up manifold slots for other machine functions.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350-08B the Right Choice?
When sizing, compare neighboring bores: the 63mm bore offers 1559 N push at 0.5 MPa, while the 100mm bore provides 3927 N. This 80mm bore gives 2513 N. Confirm the DC24V terminal entry and PT threads suit your supply. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Without air, the valve routes flow but does not lock the piston; add an external rod lock or pilot-operated check valve to hold loads. For this 350mm stroke, use external guides to prevent rod bending and side-load damage.
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 SAUF80X350-08B FAQ
It generates 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, max 4 cycles/sec) driven by a DC24V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate in the 0.15-0.8 MPa valve window.
This specific SKU lacks the S suffix for a magnet, so it cannot take a magnetic switch. The default action retracts the rod when the coil is energized; you can reconfigure it to extend when energized by repositioning the valve. The valve only routes air, so it is not a load lock.
