Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 75mm stroke and a built-in 4M210-06 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 SAUF40X75-06B
The SAUF40X75-06B is a double-acting profile cylinder with a built-in AirTAC 4M210 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. It has a 1/4" cylinder port, an M12x1.25 rod thread, and 21mm adjustable cushions.
Driven by a 4M210-06 valve (1/8" port, Cv 0.78, 5 cycles/s), it operates on DC24V via terminal entry. The cylinder body rates to 1.0 MPa, but the assembled unit must run within the 0.15-0.8 MPa valve window. At 0.5 MPa it pushes 628 N and pulls 528 N. For sizing, expect a safe working load around 377 N, or a vertical lift capacity of roughly 32 kg 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 (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 SAUF40X75-06B Is Used
Modular Assembly Cells
Ideal for decentralized clamping where one coil signal per actuator eliminates long tube runs back to a central manifold.
Diverter Gates
Provides standalone push-off action on conveyor lines, saving manifold space while delivering 628 N push at 0.5 MPa.
Component Insertion
Compact profile cylinder fits tight machine footprints, using its built-in 4M210 valve to cycle parts at up to 5 Hz.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X75-06B the Right Choice?
Size by force: this 40mm bore delivers 628 N push at 0.5 MPa; step up to a 50mm bore for 982 N, or down to a 32mm bore for 402 N. Confirm the DC24V terminal coil and 1/8" valve port meet your supply. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Because this SKU lacks a magnet, it cannot take a magnetic switch. The 4M210 valve routes air but is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For this 75mm stroke side-load is minimal, but for strokes over 300mm add a guide.
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 SAUF40X75-06B FAQ
It pushes 628 N and pulls 528 N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s) running on DC24V terminal entry. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
By default the rod retracts when the coil is energised, but you can reposition the valve to make it extend-when-energised. The valve only routes air; it is not a load lock, so add an external rod lock or pilot-operated check valve if you need to hold a load.
