The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X125S-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 125mm 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 SAUF50X125S-06B 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 50mm bore has a 1/4" cylinder port, an M16x1.5 rod thread, and 21mm adjustable cushions.
The integrated valve features a 1/8" port, 14mm2 flow (Cv 0.78), and runs at 5 cycles/sec. The DC24V coil offers IP65 protection with a 0.05s response. Size force within the 0.15-0.8 MPa valve window; at 0.5 MPa it pushes 982 N and pulls 825 N. This yields a safe working load of roughly 589 N, or a 50 kg vertical lift with a 2:1 margin. The S suffix adds a piston magnet for CMSG/DMSG/EMSG switches.

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 independent clamping stations on a large machining line where running individual air lines back to a central manifold is impractical.
Powers sorting gates on a conveyor network directly from local DC24V signals, removing the need for a dedicated remote valve island.
Drives localized package stops in high-throughput distribution hubs, cutting installation time by integrating the 4M210 valve directly on the cap.
Size by checking both neighbours: the 40mm bore pushes 628 N at 0.5 MPa, while the 63mm bore pushes 1559 N. This 50mm unit delivers 982 N push and 825 N pull at 0.5 MPa. Confirm the DC24V terminal entry and 1/8" valve port suit your supply. The cylinder body rates to 1.0 MPa, but the assembled unit must operate at 0.15-0.8 MPa. Default action retracts the rod when energised; reposition the valve to extend on signal. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold loads. For this 125mm stroke, side-load is minimal, but always guide the load for longer strokes.
Quick checklist
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) driven by a DC24V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa range.
Yes. The default action retracts the rod when energised, but you can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This allows easy adaptation to machine logic without extra plumbing.
