Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450S-06B is a genuine double-acting profile-type cylinder with a Ø40mm bore, 450mm 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 SAUF40X450S-06B
The SAUF40X450S-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. The bore dictates a 1/4" cylinder port, while the valve features a 1/8" port. A piston magnet is included for CMSG/DMSG/EMSG switches.
Operating within the 0.15-0.8 MPa valve window, this model delivers 628 N push and 528 N pull at 0.5 MPa. The safe working load is roughly 377 N, allowing a vertical lift of about 32 kg with a 2:1 margin. The integrated 4M210-06 valve provides 14 mm2 flow (Cv 0.78) and handles up to 5 cycles per second. The DC24V terminal coil offers IP65 protection and uses a PT thread with PU tube Ø8xØ5.

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 SAUF40X450S-06B Is Used
Divert Gate Actuation
Drives a decentralized diverting gate on a packaging conveyor using a single DC24V signal, eliminating long tube runs back to a central manifold.
Carton Push-Off Station
Pushes cartons off a roller line at up to 5 cycles per second, with the built-in 4M210 valve ensuring fast local response without manifold slot usage.
Component Sorting Fixture
Sorts parts on an assembly line using the magnetic piston for position feedback, while the integrated valve minimizes cabinet plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450S-06B the Right Choice?
Size by comparing neighboring bores: the 32 mm bore yields 402 N push at 0.5 MPa, while the 50 mm bore yields 982 N. This 40 mm bore provides 628 N push at 0.5 MPa, making it suitable for moderate loads. Confirm the DC24V terminal entry and 1/8" valve port meet your electrical and pneumatic supply requirements. The default action retracts the rod when energized, but you can reposition the valve to extend on energization. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because the 450 mm stroke exceeds 300 mm, add external guides to prevent rod bending and side-load wear. The valve only routes air; it is not a lock, so add an external rod lock or pilot-operated check valve to hold loads safely.
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 SAUF40X450S-06B FAQ
It delivers 628 N push and 528 N pull at 0.5 MPa using a built-in 4M210-06 valve (Cv 0.78, 1/8" port). The DC24V coil operates at up to 5 cycles per second. Although the cylinder body rates to 1.0 MPa, you must size force within the 0.15-0.8 MPa valve operating window.
No. The built-in 5/2 valve routes air but does not lock the piston, and the air cushion only decelerates near stroke end. If air is lost, the load will drift. For vertical load holding, install an external rod lock or a pilot-operated check valve.
