Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900S-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900S-10B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 900mm 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 SAUF80X900S-10B
The SAUF80X900S-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 is shorter than an ISO 15552 unit of the same bore. This 80mm bore model includes a piston magnet for switches and delivers a 2513N push force at 0.5MPa. The cylinder port is 3/8" and the rod thread is M20x1.5.
The integrated 4M310-10 valve has a 3/8" port, Cv 1.68 flow, and cycles up to 4 times per second. The DC24V coil offers IP65 protection with terminal entry. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within the 0.15-0.8MPa valve window. Based on the 0.5MPa push force, the safe working load is about 1508N, allowing a vertical lift of roughly 128kg 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 SAUF80X900S-10B Is Used
Decentralized Sorting Diverter
Mounts directly on the conveyor frame to push packages, needing only one electrical signal to actuate without a central valve manifold.
Long-Reach Vertical Gate
Uses the 900mm stroke to open large bin doors, relying on the built-in 4M310-10 valve to save tubing across the storage facility.
Independent Machine Clamp
Provides standalone clamping on a multi-station machine, eliminating the pneumatic routing complexity of remote valve banks.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X900S-10B the Right Choice?
When sizing, compare neighboring bores: the 63mm bore offers 1559N push at 0.5MPa, while the 100mm bore provides 3927N. This 80mm bore yields 2513N push and 2268N pull at 0.5MPa, peaking at 4021N push at the 0.8MPa valve limit. Confirm your coil is DC24V with terminal entry before ordering. By default the rod retracts when energized, but repositioning the valve switches it to extend-when-energized. Because the 900mm stroke exceeds 300mm, use an external guide to prevent rod bending and side-load damage. The valve only routes air; it is not a lock. To hold a load on air loss, add an external rod lock or pilot-operated check valve.
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 SAUF80X900S-10B FAQ
It delivers 2513N push and 2268N pull at 0.5MPa, reaching 4021N push at 0.8MPa. The built-in valve is a 4M310-10 with Cv 1.68. The DC24V coil runs at 0.15-0.8MPa. Although the cylinder body rates to 1.0MPa, the assembled unit must stay within the 0.15-0.8MPa valve window.
The default action retracts the rod when the coil is energized. You can reconfigure it to extend-when-energized by repositioning the built-in valve. This self-switching design removes the need for a remote valve, saving manifold space and tubing.
