Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225S-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 225mm 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 SAUF40X225S-06B
The SAUF40X225S-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. The bore dictates a 1/4" cylinder port and an M12x1.25 rod thread, while the valve features a 1/8" port. A piston magnet is included for CMSG/DMSG/EMSG switches.
Operating on DC24V with terminal entry, the integrated valve delivers a 14 mm2 flow (Cv 0.78) at up to 5 cycles per second. The cylinder body rates to 1.0 MPa, but the valve limits the assembled unit to a 0.15-0.8 MPa window. At 0.5 MPa it pushes 628 N and pulls 528 N. This yields a safe working load of roughly 377 N, or a vertical lift capacity of about 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 SAUF40X225S-06B Is Used
Compact Clamping Station
Ideal for decentralized clamping where the integrated DC24V valve switches the actuator directly at the fixture, eliminating long tube runs back to a central manifold.
Inline Divert Gate
Provides responsive product diversion on a conveyor. The built-in 4M210 valve achieves up to 5 cycles per second, ensuring rapid gate actuation without remote plumbing.
Decentralized Stopper Cylinder
Perfect for pallet stops in large machines. The profile cylinder saves installation time by mounting independently, using a single electrical signal to drive the 225 mm stroke.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X225S-06B the Right Choice?
When sizing, compare neighboring bores: the 32 mm bore offers 402 N push at 0.5 MPa, while the 50 mm bore provides 982 N. This 40 mm bore generates 628 N push and 528 N pull at 0.5 MPa. Confirm the DC24V coil and terminal entry suit your control system. The rod retracts when energized by default, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder rating. The valve only routes air; it is not a lock, so add an external rod lock or pilot-operated check valve to hold loads. For this 225 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 SAUF40X225S-06B FAQ
It generates 628 N push and 528 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5/2 solenoid) running on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
By default the rod retracts when the coil is energized. You can reconfigure it to extend when energized simply by repositioning the built-in valve. Note that the valve only routes air; it does not lock the load, so you need an external rod lock for holding.
