Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350-10B 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 SAUF80X350-10B
The SAUF80X350-10B 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 makes it shorter than an ISO 15552 unit of the same bore. It uses a 3/8" valve port, a 3/8" cylinder port, and a Ø25 mm rod with an M20x1.5 thread.
Operating within the valve's 0.15-0.8 MPa window, it delivers a 2513 N push force at 0.5 MPa. The safe working load is roughly 1508 N, and the vertical lift capacity is about 128 kg with a 2:1 margin. The integrated valve flows 30 mm2 (Cv 1.68) and handles up to 4 cycles per second. The DC24V coil offers IP65 protection with a 0.05 s response time. This SKU lacks a magnet and cannot accept a sensor.

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 SAUF80X350-10B Is Used
Package Diverter
Uses one coil signal to push packages off a main belt without running air lines back to a central manifold.
Pallet Stop Gate
Decentralized actuation drops a heavy stop pin at a roller conveyor junction using the 4021 N push force.
Machine Guard Door
Opens a large access panel directly from a local valve island slot, saving tubing across the machine base.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X350-10B the Right Choice?
When sizing, compare neighbouring bores: the 63 mm bore provides 1559 N push at 0.5 MPa, while the 100 mm bore offers 3927 N. This 80 mm bore yields 2513 N push and 2268 N pull at 0.5 MPa. Confirm the DC24V terminal entry and PT thread suit your control panel. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa range. The rod retracts when the coil is energised; reposition the valve to switch to extend-when-energised. Because this is a 350 mm stroke, use external guides to prevent rod bending and side-load wear. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load on air loss.
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 SAUF80X350-10B FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa, reaching 4021 N at 0.8 MPa. The built-in valve is a 4M310-10 with a 3/8" port, Cv 1.68, and 30 mm2 flow. The coil is DC24V with terminal entry. You must size the force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend when energised. The valve only routes air and is not a load lock. If air is lost, the piston drifts and the 28 mm cushion only decelerates near stroke end. Add an external rod lock or pilot-operated check valve to hold a vertical load.
