Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100-08B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 100mm 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 SAUF40X100-08B
The SAUF40X100-08B is an extruded aluminum profile-type double-acting cylinder with a built-in AirTAC 4M 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The 40mm bore delivers 628N push and 528N pull at 0.5MPa, operating safely inside the valve's 0.15-0.8MPa window.
This unit uses a 4M210-08 valve with a 1/4" port, 16mm2 flow (Cv 0.89), and a 5 cycle/s max frequency. The DC24V terminal entry coil is IP65 rated. Computed buyer insight: safe working load is roughly 377N (60% of the 0.5MPa push force), allowing a 32kg vertical lift with a 2:1 margin. The cylinder port is 1/4" with an M12x1.25 rod thread.

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 SAUF40X100-08B Is Used
Inline Diverter Gate
Decentralized conveyor sorting uses one coil signal to actuate the diverter flap directly at the line, removing long tube runs back to a central manifold.
Independent Clamping Station
A standalone machining fixture clamps parts using the integrated 4M210-08 valve, freeing up manifold slots for other actuators on the cell.
Localized Package Stopper
A packing line stopper arm deploys via the built-in valve, simplifying installation by requiring only a single DC24V electrical connection and air supply.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X100-08B the Right Choice?
Size force between the 32mm bore (402N push) and 50mm bore (982N push) at 0.5MPa. This 40mm bore gives 628N push. Confirm the DC24V terminal entry coil and 1/4" valve port meet your supply. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Size strictly within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body rating. This SKU lacks a magnet and cannot take a sensor. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. For this 100mm stroke, side-load guides are optional but recommended for rigid mounting.
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 SAUF40X100-08B FAQ
It delivers 628N push and 528N pull at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s max) with a DC24V terminal entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
The default action retracts the rod when energised. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This self-switching design means no remote valve is needed, saving tubing and installation time.
