Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X80-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X80-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 80mm 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.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X80-06A
The SAUF50X80-06A is an AirTAC double-acting profile cylinder with a built-in 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 makes it shorter than an ISO 15552 unit of the same bore. It uses a 1/4" cylinder port, a 1/8" valve port, and a Ø20 mm rod with an M16x1.5 thread.
This 50 mm bore generates 982 N push and 825 N pull at 0.5 MPa. A practical computed insight is a safe working load of roughly 589 N, or a vertical lift of about 50 kg with a 2:1 margin. The integrated valve flows 14 mm2 (Cv 0.78) at up to 5 cycles per second. The AC220V terminal entry coil is IP65 rated. Because this SKU lacks the magnet suffix, it cannot take a magnetic switch. Size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.

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 SAUF50X80-06A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station needs independent control without routing tubes back to a central manifold.
Inline Diverter Gate
Perfect for a conveyor diverter arm requiring a single AC220V signal to actuate, saving manifold space on the main line.
Compact Package Stopper
Suits a packaging line stopper mechanism where the integrated valve minimizes installation time and physical footprint.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X80-06A the Right Choice?
Size by checking both neighboring bores against your load: the 40 mm bore yields 628 N push while the 63 mm bore yields 1559 N push at 0.5 MPa. This 50 mm unit provides 982 N push, offering a safe working load of about 589 N. Confirm the AC220V terminal entry power and PT thread meet your specs. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Always size within the 0.15-0.8 MPa valve range. The valve routes air and is not a lock; if power or air drops, the piston drifts and the 21 mm cushion only decelerates near stroke end. Add an external rod lock or pilot-operated check valve to hold a load. For this 80 mm stroke side-load is minimal, but for strokes over 300 mm add a guide.
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 SAUF50X80-06A FAQ
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 max) driven by an AC220V terminal entry coil. Although the cylinder body rates to 1.0 MPa, you must size force within the 0.15-0.8 MPa assembled valve operating window.
No. The 5/2 valve only routes air; it is not a lock, so the piston drifts on air loss. Add an external rod lock or pilot-operated check valve for load holding. Additionally, this specific SKU lacks a magnet and cannot take a magnetic switch.
