Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400S-08B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 400mm 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 SAUF80X400S-08B
The SAUF80X400S-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 in decentralized setups. The 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, operating safely within the valve's 0.15-0.8MPa range.
The integrated 4M310-08 valve features a 1/4 inch port, 25mm2 flow (Cv 1.4), and switches up to 4 cycles per second. The DC24V terminal coil offers IP65 protection with a 0.05s response. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG sensors. Based on the 2513N push force at 0.5MPa, the computed safe working load is about 1508N, translating to a 128kg vertical lift 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 SAUF80X400S-08B Is Used
Decentralized Divert Gate
Actuates a sorting diverter directly on the conveyor frame without routing long air lines back to a central manifold.
Independent Pallet Stop
Deploys a heavy pallet stopper on a roller lane using a single DC24V signal, simplifying modular cell installation.
Machine Tool Clamp
Provides isolated clamping on a large machining center, saving manifold slots while offering position feedback via the magnet.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400S-08B the Right Choice?
Size by checking both neighbor bores: the 63mm bore yields 1559N push while the 100mm bore yields 3927N push at 0.5MPa. This 80mm bore provides 2513N push at 0.5MPa, peaking at 4021N at the 0.8MPa valve limit. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts when the coil is energised, but you can reposition the valve to extend on energisation. The integrated valve routes air; it does not lock the piston, so add an external rod lock or pilot-operated check valve to hold loads safely. For this 400mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF80X400S-08B FAQ
It generates 2513N push and 2268N pull at 0.5MPa, reaching 4021N at 0.8MPa. The built-in 4M310-08 valve has a 1/4 inch port, Cv 1.4, and runs a DC24V coil. You must size force within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder body rating. The 80mm bore uses a 3/8 inch cylinder port.
By default the rod retracts when the coil is energised. You can reconfigure it to extend when energised simply by repositioning the integrated valve. Because the valve only routes air, it cannot hold a load without air pressure; always add an external rod lock for suspended loads.
