Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400S-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400S-10B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 400mm 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 SAUF80X400S-10B
The SAUF80X400S-10B is a double-acting profile 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 extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 3/8" valve port, 3/8" cylinder port, and a piston magnet for CMSG/DMSG/EMSG switches.
Operating within the valve's 0.15-0.8 MPa window, this 80mm bore delivers 2513 N push force at 0.5 MPa. The 4M310 valve provides 30 mm2 flow (Cv 1.68) at up to 4 cycles per second. The DC24V coil offers IP65 protection with a 0.05 s response. 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 SAUF80X400S-10B Is Used
Decentralized Diverters
Drives package diverters directly at the conveyor lane without routing air lines back to a central manifold.
Machine Tool Clamps
Provides independent clamping on large machining centers where a single coil signal per clamp saves installation time.
Vertical Lift Gates
Actuates material handling gates with a 128 kg vertical lift capacity while keeping the control cabinet simple.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400S-10B the Right Choice?
When sizing, compare neighboring bores: the 63mm bore yields 1559 N push at 0.5 MPa, while the 100mm bore reaches 3927 N. This 80mm actuator provides 2513 N at 0.5 MPa. Confirm your coil is DC24V with terminal entry before ordering. The rod retracts when the coil is energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and does not hold the load on pressure loss; add an external rod lock or pilot-operated check valve for holding. 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-10B FAQ
It generates 2513 N push and 2268 N pull at 0.5 MPa, reaching 4021 N at 0.8 MPa. The built-in valve is a 4M310-10 with 30 mm2 flow (Cv 1.68) and a 3/8" port. The DC24V coil runs at up to 4 cycles per second. You must size the force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
By default the rod retracts when the coil is energized, but you can reposition the valve to make it extend on signal. The valve only routes air; it is not a load lock. If air is lost, the piston drifts and the 28mm cushion only decelerates near stroke end. For true load holding, install an external rod lock or pilot-operated check valve.
