Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225-10B is a genuine double-acting profile-type cylinder with a Ø80mm bore, 225mm 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 SAUF80X225-10B
The SAUF80X225-10B is a double-acting profile-type cylinder with a built-in AirTAC 4M310 5-port 2-position solenoid valve mounted on the cap. One coil signal drives the cylinder directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore.
Operating within the valve's 0.15-0.8 MPa window, this 80mm bore delivers 2513N push force at 0.5MPa. The integrated 4M310-10 valve has a 3/8" port, Cv 1.68 flow, and cycles up to 4 times per second. For sizing, the safe working load is roughly 1508N, and it can vertically lift about 128kg with a 2:1 margin. The cylinder body rates to 1.0MPa, but the assembled unit is limited by the valve to 0.8MPa.

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 SAUF80X225-10B Is Used
Machine Tool Clamping
Decentralized clamping on a large CNC machining center where routing long air lines to a central manifold is impractical.
Diverting Gate Actuation
Independent diverting arms on a packaging conveyor, using one coil signal per station to save manifold slots.
Pallet Stopper Control
Individual pneumatic stoppers on an assembly line, switched locally without extra tubing runs back to a main panel.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF80X225-10B the Right Choice?
When sizing, compare neighboring bores: the 63mm bore provides 1559N push at 0.5MPa, while the 100mm bore offers 3927N. This 80mm bore yields 2513N push and 2268N pull at 0.5MPa. Confirm your coil is DC24V with terminal entry and PT threads. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Remember the 1.0MPa cylinder body limit is capped at 0.15-0.8MPa by the built-in valve. This SKU lacks a magnet (-S), so it cannot accept magnetic switches. For stroke lengths over 300mm, use side-load guides to prevent rod damage.
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 SAUF80X225-10B FAQ
It generates 2513N push and 2268N pull at 0.5MPa, reaching 4021N push at 0.8MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, max 4 cycles/sec). The coil is DC24V with terminal entry. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within the valve's 0.15-0.8MPa range.
No, the built-in 5/2 valve only routes air and is not a load lock. If air is lost, the piston drifts and the 28mm cushions only decelerate near stroke end. To hold a load securely, add an external rod lock or a pilot-operated check valve.
