Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 150mm 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 SAUF40X150-06B
The SAUF40X150-06B 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 unit of the same bore. This model uses a 1/4" cylinder port and an M12x1.25 rod thread.
Operating within the valve's 0.15-0.8 MPa range, it delivers 628 N push force at 0.5 MPa. A practical computed insight sizes the safe working load at roughly 377 N, with a vertical lift capacity around 32 kg using a 2:1 margin. The integrated 4M210-06 valve features a 1/8" port, 14 mm2 flow (Cv 0.78), and cycles up to 5 times per second. The DC24V coil offers IP65 protection with terminal entry, and because this SKU lacks a magnet suffix, 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 SAUF40X150-06B Is Used
Clamp Station
Decentralized clamping on a machining line where the integrated valve provides immediate local actuation without running long tubing back to a central manifold.
Divert Gate
Independent diverting gate control on a conveyor, using the single coil signal to switch the 150 mm stroke directly at the actuator mounting point.
Package Stopper
Remote package stopper in a high-speed logistics hub, saving manifold space and simplifying wiring by utilizing the built-in 4M210 valve.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X150-06B the Right Choice?
When sizing, compare neighboring bores: the 32 mm bore pushes 402 N at 0.5 MPa, while the 50 mm bore reaches 982 N. This 40 mm bore provides 628 N push and 528 N pull at 0.5 MPa, sized strictly within the 0.15-0.8 MPa valve window rather than the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT thread meet your electrical specs. By default the rod retracts when the coil is energized, but you can reposition the valve to extend on signal. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve for held loads. For this 150 mm stroke, ensure adequate side-load guidance.
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 SAUF40X150-06B FAQ
It delivers 628 N push and 528 N pull at 0.5 MPa, operating strictly within the built-in valve's 0.15-0.8 MPa working range. The integrated valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max) driven by a DC24V terminal-entry coil. The cylinder body rates to 1.0 MPa, but the assembled unit must be sized within the 0.15-0.8 MPa valve limit.
Yes, the default action retracts the rod when the coil is energized, but you can reposition the valve to extend on signal. The 5/2 valve only routes air; it is not a load lock. The piston will drift on air loss, so install an external rod lock or pilot-operated check valve if you need to maintain position.
