Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400-10B 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 SAUF80X400-10B
The SAUF80X400-10B 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 is shorter than an ISO 15552 unit of the same bore. This SKU uses terminal entry, PT threads, and Ø10xØ6.5 PU tubing.
It delivers 2513 N push at 0.5 MPa, rising to 4021 N at the 0.8 MPa assembled limit. The 4M310-10 valve provides 3/8" ports, Cv 1.68, and 4 cycles/sec. Computed buyer insight: safe working load is ~1508 N (60% of the 0.5 MPa push), allowing a ~128 kg vertical lift with a 2:1 margin. The cylinder body rates to 1.0 MPa, but size force within the valve's 0.15-0.8 MPa window.

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 SAUF80X400-10B Is Used
Divert Gate Actuation
Decentralized divert gates use this self-switching cylinder to push packages without running long air lines back to a central manifold.
Pallet Stopper Control
One coil signal raises and lowers heavy pallet stops directly at the station, saving manifold slots and simplifying machine plumbing.
Press Ejection System
Ejects parts locally inside a large press. The integrated 4M310 valve handles the high flow needed for rapid ejection cycles.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X400-10B the Right Choice?
Size between neighbours: bore 63 gives 1559 N push at 0.5 MPa, while bore 100 gives 3927 N. This 80 mm bore provides 2513 N push at 0.5 MPa. Confirm the DC24V coil and terminal entry suit your control panel. The rod retracts when energised, but you can reconfigure it to extend by repositioning the valve. The cylinder body rates to 1.0 MPa, but the assembled unit operates at 0.15-0.8 MPa. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. With a 400 mm stroke, use external guides to prevent rod bending and side 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 SAUF80X400-10B FAQ
It delivers 2513 N push and 2268 N pull at 0.5 MPa, reaching 4021 N push at 0.8 MPa. The built-in valve is a 4M310-10 (5/2 solenoid) with 3/8" ports, Cv 1.68, and 4 cycles/sec. The coil is DC24V with terminal entry. The cylinder body rates to 1.0 MPa, but the assembled unit must operate within the valve's 0.15-0.8 MPa window.
No, the built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. Also, this specific SKU lacks the -S suffix, so it cannot take a magnetic switch. The default action retracts the rod when energised, but you can reposition the valve to extend on signal.
