The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X225S-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 225mm 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 SAUF50X225S-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 directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 50mm bore, 225mm stroke, and a piston magnet for switches.
The integrated 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and handles 5 cycles/sec. The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly within the 0.15-0.8 MPa valve window. At 0.5 MPa it delivers 982 N push and 825 N pull. The computed safe working load is roughly 589 N, allowing a vertical lift of about 50 kg with a 2:1 margin. The bore dictates a 1/4" cylinder port, while the valve uses PT threads and a terminal AC220V coil.

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.
Decentralized sorting line where each diverter needs its own direct coil signal without routing long tubing back to a central manifold.
Machine fixtures requiring individual clamping control, saving manifold slots and simplifying installation by integrating the 4M210 valve on the cap.
Light assembly press delivering 589 N safe working load, using the built-in magnet for position confirmation before the press stroke completes.
Size force between the 0.15-0.8 MPa valve limits: this 50mm bore gives 982 N push at 0.5 MPa, sitting between the 40mm (628 N) and 63mm (1559 N) options. The AC220V terminal entry coil is fixed; confirm your voltage. By default the rod retracts when energised, but you can reposition the valve to extend on signal. The built-in valve routes air and is not a load lock, so add an external rod lock or pilot-operated check valve to hold a load. Because the 225mm stroke exceeds 300mm, ensure external side-load guidance. The -S suffix supports CMSG/DMSG/EMSG switches.
Quick checklist
It delivers 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-06 with 1/8" port and Cv 0.78. The cylinder body rates to 1.0 MPa, but the assembled unit must operate within the 0.15-0.8 MPa valve window. The coil is AC220V with terminal entry.
By default the rod retracts when the coil is energised. You can reconfigure it to extend when energised simply by repositioning the built-in valve. Note that the valve only routes air; it is not a load lock, so you need an external rod lock or pilot-operated check valve to hold a load.
