Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300S-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 300mm 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 SAUF80X300S-08B
The SAUF80X300S-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. A piston magnet is included for CMSG/DMSG/EMSG switches.
The 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, operating within the valve's 0.15-0.8MPa window. The integrated 4M310-08 valve has a 1/4" port, Cv 1.4, and 4 cycles/sec. Computed insight: safe working load is ~1508N, allowing a vertical lift of ~128kg with a 2:1 margin. The cylinder port is 3/8", with a 28mm adjustable cushion and M20x1.5 rod thread.

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 SAUF80X300S-08B Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center. The integrated valve provides rapid local actuation without routing long control lines back to a central manifold.
Diverting Gate Control
Operating heavy diverting gates on a packaging line. The 80mm bore provides high push force, while the built-in 4M310 valve ensures immediate response for high throughput.
Pallet Stopper Actuation
Controlling heavy pallet stops in automated storage systems. One coil signal per actuator simplifies wiring and eliminates the need for a dedicated remote valve island.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X300S-08B the Right Choice?
Size by force: the 80mm bore yields 2513N push at 0.5MPa, sitting between the 63mm (1559N) and 100mm (3927N) options. Keep pressure within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body rating. This DC24V terminal entry unit defaults to retract-when-energised but can be reconfigured to extend by repositioning the valve. For the 300mm stroke, use external guides to prevent rod bending and side loads. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve for held loads.
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 SAUF80X300S-08B FAQ
It delivers 2513N push and 2268N pull at 0.5MPa, reaching 4021N at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec) with a DC24V terminal entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
By default, the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve. The valve only routes air; it is not a load lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve for load holding.
