Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450-06B 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 SAUF40X450-06B
The AirTAC SAUF40X450-06B is a double-acting profile cylinder with a built-in 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 makes it shorter than an ISO 15552 cylinder of the same bore. This SKU lacks a magnet and cannot take a magnetic switch.
It delivers 628 N push and 528 N pull at 0.5 MPa. The 1/4" cylinder port and M12x1.25 rod thread are fixed by the 40 mm bore. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and handles 5 cycles/sec. Size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. Safe working load is about 377 N, allowing a 32 kg vertical lift 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 SAUF40X450-06B Is Used
Decentralized Conveyor Diverter
Mounts directly at the divert station. One DC24V signal actuates the 450 mm stroke without running long tubing back to a central manifold.
Independent Pack Gate
Ideal for a standalone packaging gate where saving a manifold slot matters. The built-in 4M210 valve switches the 628 N push force instantly.
Machine Tool Loading Arm
Drives a loading arm on a large machine tool. The compact profile cylinder fits tight cells while the integrated valve simplifies wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450-06B the Right Choice?
When sizing, compare neighbouring bores: a 32 mm bore yields 402 N push at 0.5 MPa, while a 50 mm bore yields 982 N. This 40 mm bore gives 628 N push. Confirm the DC24V terminal entry and PT thread before ordering. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. The integrated valve limits operation to 0.15-0.8 MPa. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 450 mm stroke, use an external guide to prevent rod bending and side-load damage.
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 SAUF40X450-06B 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/sec) running on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit operates at 0.15-0.8 MPa.
No. The built-in 5/2 valve routes air but does not lock the piston. If air is lost, the piston drifts. For load holding, install an external rod lock or pilot-operated check valve. The default action retracts when energised, but you can reposition the valve to extend on signal.
