Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 50mm 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.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50-08A
The SAUF50X50-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One coil signal drives the rod, 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 has a 1/4" cylinder port, an M16x1.5 rod thread, and 21mm adjustable cushions.
Operating in the 0.15-0.8 MPa valve window, it delivers 982N push and 825N pull at 0.5 MPa. The 4M210-08 valve flows 16mm2 (Cv 0.89) at up to 5 cycles/sec. The AC220V terminal coil is IP65 rated. Based on the 0.5MPa push force, the safe working load is about 589N, and it can vertically lift roughly 50kg 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.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
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.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50-08A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station switches itself via one AC220V signal, removing long tube runs back to a central manifold.
Inline Diverting
Perfect for a conveyor diverter gate that needs independent 5 cycles/sec actuation without dedicating a manifold slot to every lane.
Package Stops
Fits packaging lines needing a compact 50mm stroke stopper; the built-in valve simplifies wiring and air hookup at each divert point.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50-08A the Right Choice?
Size by force: this 50mm bore gives 982N push at 0.5MPa; step down to a 40mm bore for 628N, or up to a 63mm bore for 1559N. Confirm the AC220V terminal entry suits your control. The rod retracts when energised but you can reconfigure it to extend by repositioning the valve. Size within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. This 50mm stroke meets the 50mm minimum. With no -S suffix, this SKU cannot take a magnetic switch.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50-08A FAQ
It pushes 982N and pulls 825N at 0.5MPa. The built-in 4M210-08 valve has a 1/4" port, Cv 0.89, and runs an AC220V terminal coil. You must size the force within the valve's 0.15-0.8MPa operating window, even though the cylinder body rates to 1.0MPa.
Yes. The default action retracts the rod on energisation, but you can reposition the valve on the cap to make it extend when energised. This keeps your one-signal switching logic flexible without extra remote valves.
