The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF40X300-06A is a genuine double-acting profile-type cylinder with a Ø40mm bore, 300mm 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 SAUF40X300-06A 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. This SKU uses terminal entry with PT threads and has no magnet, so it cannot take a magnetic switch.
It delivers 628 N push and 528 N pull at 0.5 MPa. The integrated valve flows 14 mm2 (Cv 0.78) at a 1/8" port, cycling up to 5 times per second. Size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. The computed safe working load is about 377 N (60% of the 0.5 MPa push), allowing a vertical lift of roughly 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.

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.
Mounts directly at the diverter station on a long conveyor line. One AC220V signal actuates the 300 mm stroke without routing tubing back to a central manifold.
Ideal for a standalone clamping fixture on a large machine. The integrated 4M210 valve provides 628 N push at 0.5 MPa without consuming a manifold slot.
Controls a 300 mm stop gate in a zoning system. The built-in valve allows local control, saving installation time and tubing across the warehouse framework.
When sizing, compare neighbours: a 32 mm bore gives 402 N push at 0.5 MPa, while a 50 mm bore yields 982 N. This 40 mm bore provides 628 N push and 528 N pull at 0.5 MPa. Confirm the AC220V terminal coil and PT thread suit your system. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Always size within the 0.15-0.8 MPa valve operating range. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. At 300 mm stroke, use an external guide to prevent rod bending and side-load wear.
Quick checklist
It delivers 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) driven by an AC220V terminal coil. The cylinder body rates to 1.0 MPa, but you must size force within the 0.15-0.8 MPa valve operating window. The cylinder air port is 1/4".
The valve routes air and is not a load lock; the piston drifts on air loss, so add an external rod lock or pilot-operated check valve to hold a load. By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve.
