Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X80-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X80-08B 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.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X80-08B
The AirTAC SAUF50X80-08B is a double-acting profile cylinder with a built-in 4M210-08 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 cylinder of the same bore. This 50mm bore has a 1/4" cylinder port, an M16x1.5 rod thread, and 21mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa window, it delivers 982N push and 825N pull at 0.5MPa. The integrated valve provides 1/4" porting, 16mm2 flow (Cv 0.89), and handles up to 5 cycles/sec. The DC24V terminal coil is IP65 rated. For sizing, the safe working load is roughly 589N, allowing a 50kg vertical lift with a 2:1 margin. Note this SKU lacks a magnet and cannot take sensors.

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 SAUF50X80-08B Is Used
Inline Diverter Gate
Uses one DC24V signal to swing a diverter arm on a packaging line, removing the need for a centralized valve manifold.
Independent Clamping Station
Provides localized 982N clamping force on an assembly cell, saving tubing and simplifying maintenance.
Decentralized Package Stop
Acts as a standalone stopper block on a roller conveyor, switching itself directly from the local PLC output.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X80-08B the Right Choice?
Size by checking both neighboring bores: the 40mm bore offers 628N push at 0.5MPa, while the 63mm bore provides 1559N. This 50mm bore gives 982N push and 825N pull at 0.5MPa. Always size force within the valve's 0.15-0.8 MPa operating range, never the 1.0 MPa cylinder body rating. Confirm the DC24V terminal coil and PT thread suit your control system. By default the rod retracts when energized, but you can reposition the valve to extend on signal. Since this 80mm stroke is under 300mm, side-load guides are less critical. The valve routes air but does not lock the load; add an external rod lock or pilot-operated check valve for hold. Without a magnet, this SKU cannot accept position sensors.
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 SAUF50X80-08B FAQ
It generates 982N push and 825N pull at 0.5MPa. The built-in valve is a 4M210-08 (5/2 solenoid) with 1/4" porting, Cv 0.89, and a DC24V terminal coil. You must size the force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
The valve routes air and is not a load lock, so the piston drifts on air loss; add an external rod lock or pilot check valve to hold. By default the rod retracts when the coil is energized, but you can reposition the valve to extend on signal.
