The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X450-06A 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.
The SAUF40X450-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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 unit of the same bore. It features a 1/4" cylinder port, an M12x1.25 rod thread, and adjustable cushions.
Operating within the valve's 0.15-0.8 MPa range, this 40mm bore generates 628N push and 528N pull at 0.5 MPa. The integrated valve flows 14 mm2 (Cv 0.78) at 1/8" and handles 5 cycles/sec. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 377N (about 60% of the 0.5 MPa push), allowing a 32kg vertical lift with a 2:1 margin. This SKU lacks a magnet and cannot accept a sensor.

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.

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.
Ideal for a machining cell where each clamping station needs independent control without running long tubing back to a central manifold.
Perfect for driving a sorting gate on a conveyor line, using the built-in valve to switch the actuator directly at the divert point.
Suits a packaging line push-off mechanism, saving installation time by mounting the valve and cylinder as one self-contained unit.
When sizing, compare neighbouring bores: a 32mm bore yields 402N push at 0.5 MPa, while a 50mm bore provides 982N. This 40mm unit delivers 628N push and 528N pull at 0.5 MPa. Always size force within the valve's 0.15-0.8 MPa operating window, not the cylinder body's 1.0 MPa rating. Confirm the AC220V terminal entry and PT thread meet your electrical specs. The rod retracts when the coil is energised; reposition the valve to reverse this to extend-when-energised. Because the 450mm stroke exceeds 300mm, use an external guide to prevent rod bending and side-load wear. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load safely.
Quick checklist
It generates 628N push and 528N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec). The coil is AC220V with terminal entry. Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa operating window.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The valve only routes air; it is not a lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve for load holding.
