Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X1000-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X1000-08B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 1000mm stroke and a built-in 4M210-08 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 SAUF40X1000-08B
The SAUF40X1000-08B is a double-acting profile cylinder with a built-in AirTAC 4M210-08 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 cylinder of the same bore. This 40mm bore uses a 1/4" air port, a 16mm rod, and an M12x1.25 rod-end thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 628N push and 528N pull at 0.5 MPa. The 4M210 valve provides 16mm2 flow (Cv 0.89) and handles up to 5 cycles per second. The DC24V coil offers IP65 protection with terminal entry. Based on the 0.5MPa push force, the computed safe working load is roughly 377N, and it can vertically lift about 32kg with a 2:1 margin. This SKU lacks the S suffix for a magnet, so it cannot accept a magnetic switch.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAUF40X1000-08B Is Used
Long-Stroke Diversion
Pushes packages across a conveyor belt over a 1000mm distance using a single DC24V signal without needing a remote valve manifold.
Decentralized Press
Provides 628N clamping force at 0.5 MPa in a compact profile cylinder, ideal for distributed assembly stations saving manifold slots.
Vertical Material Gate
Lifts a 32kg gate with a 2:1 safety margin. The built-in 4M210 valve simplifies installation at distant loading bons.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X1000-08B the Right Choice?
When sizing, compare neighboring bores: a 32mm bore yields 402N push at 0.5 MPa, while a 50mm bore provides 982N. This 40mm bore gives 628N push and 528N pull at 0.5 MPa. Size your force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry coil meets your supply. The rod retracts when energized, but you can reposition the valve to extend on signal. Without air, the valve only routes flow and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. At 1000mm 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 SAUF40X1000-08B FAQ
It generates 628N push and 528N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec max) driven by a DC24V terminal entry coil. The cylinder body rates to 1.0 MPa, but you must size force within the 0.15-0.8 MPa assembled valve window.
No remote valve is needed; the integrated 4M valve switches the actuator directly. However, the valve only routes air and is not a load lock. On air loss the piston drifts. For vertical holding, add an external rod lock or pilot-operated check valve. The default action retracts when energized, but you can reposition the valve to extend on signal.
