The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X80-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 80mm stroke and a built-in 4M210-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.
The SAUF50X80-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One AC220V 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. This 50mm bore uses a 1/4" cylinder port, a Ø20mm rod with an M16x1.5 thread, and 21mm adjustable cushions.
Size force strictly within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it delivers 982N push and 825N pull. The 4M210-08 valve provides 16mm2 flow (Cv 0.89) and handles 5 cycles/sec. For sizing, the safe working load is roughly 589N, and it can vertically lift about 50kg with a 2:1 margin. This terminal-entry, PT-thread SKU lacks a magnet (-S), so it cannot accept a magnetic switch.

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 uses one coil signal to actuate independently, saving manifold tubing.
Perfect for a conveyor diverter that needs a self-contained actuator; the 4M210 valve switches the 80mm stroke rapidly at 5 cycles/sec.
Deploy as a localized package stop on a sorting line. The compact profile fits tight frames, and the 982N force handles heavy cartons.
This 50mm bore pushes 982N at 0.5MPa; step down to a 40mm bore for 628N, or up to a 63mm bore for 1559N. Confirm the AC220V terminal entry and PT threads suit your control panel. The rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. Keep operating pressure between 0.15-0.8MPa to match the valve limits, not the 1.0MPa cylinder rating. The built-in valve only routes air; it is not a lock, so add an external rod lock or pilot-operated check valve to hold a load. Since the 80mm stroke is under 300mm, side-load guides are less critical, but always align the load.
Quick checklist
It features a built-in 4M210-08 valve (Cv 0.89, 16mm2 flow) on a 50mm bore cylinder. At 0.5MPa it pushes 982N and pulls 825N. The AC220V terminal-entry coil is IP65 rated. You must size force within the valve's 0.15-0.8MPa operating window, not the cylinder's 1.0MPa max.
No remote valve is needed; the integrated 5/2 valve handles all switching from one coil signal. However, the valve only routes air and is not a load lock. If air is lost, the piston will drift. Use an external rod lock or pilot-operated check valve for load holding.
