Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450S-06A 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-06A
The SAUF40X450S-06A is a double-acting profile-type 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 S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches. The cylinder port is 1/4", the rod is Ø16 mm with an M12x1.25 thread, and adjustable cushions span 21 mm.
Operating within the valve's 0.15-0.8 MPa window, this 40 mm bore delivers 628 N push and 528 N pull at 0.5 MPa. The integrated valve is a 4M210-06 with a 1/8" port, 14 mm2 flow (Cv 0.78), and a 5 cycle/s limit. The coil is AC220V with terminal entry and IP65 rating. Computed buyer insight: safe working load is roughly 377 N (60% of the 0.5 MPa push), and vertical lift is 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 SAUF40X450S-06A Is Used
Sorting Diverter
Decentralized package sorting where one coil signal per diverter eliminates a central valve manifold and long tubing runs.
Machine Guard Gate
Independent access gate actuation on a large machine cell, using the built-in valve for simple local control without extra plumbing.
Vertical Lift Station
Lifting components up to 32 kg within a multi-station assembly line, saving manifold slots by switching directly at the cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450S-06A the Right Choice?
Size force between the 32 mm bore (402 N push at 0.5 MPa) and the 50 mm bore (982 N push). This 40 mm bore yields 628 N push at 0.5 MPa. Confirm the AC220V terminal entry matches your supply. The default action retracts the rod when energised; reposition the valve to extend on signal. Always size within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The built-in valve routes air but does not lock the piston—add an external rod lock or pilot-operated check valve for held loads. With the 450 mm stroke, add external guides to prevent rod bending and side-load wear.
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-06A FAQ
It provides 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 cycles/s max) with an AC220V terminal-entry coil. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
No. The built-in 5/2 valve routes air but is not a lock, so the piston drifts on air loss. To hold a load, install an external rod lock or pilot-operated check valve. Also, the default retract-when-energised action can be changed to extend-when-energised by repositioning the valve.
