Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000S-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 1000mm 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 SAUF50X1000S-08A
The SAUF50X1000S-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve mounted on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. This 50mm bore features a 1/4" cylinder port, an M16x1.5 rod thread, and a 21mm adjustable cushion. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG sensors.
The integrated valve has a 1/4" port, 16mm2 flow (Cv 0.89), and cycles up to 5 times per second. The cylinder body rates to 1.0 MPa, but the assembled unit operates strictly within the valve's 0.15-0.8 MPa window. At 0.5 MPa it delivers 982N push and 825N pull. For sizing, the safe working load is roughly 589N (about 60% of the 0.5 MPa push force), and it can vertically lift around 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 SAUF50X1000S-08A Is Used
Decentralized Conveyor Divert
Mounts directly at a divert station to actuate a lane guide without running long tubing back to a central manifold, saving install time.
Vertical Package Gate
Uses the one-signal retract action to lift a package gate up to 50kg with a 2:1 safety margin, ideal for independent zoning in large facilities.
Long-Stroke Material Push
Pushes parts across a 1000mm span on a machine bed, relying on the 21mm adjustable cushion to decelerate the load smoothly at stroke end.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000S-08A the Right Choice?
When sizing this model against its neighbors, a 40mm bore yields 628N push while a 63mm bore yields 1559N push at 0.5 MPa; this 50mm bore provides 982N push, fitting neatly between them. Confirm the AC220V terminal entry and PT threads match your control panel. The default action retracts the rod when energized, but you can reconfigure it to extend-when-energised by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load safely. Because the 1000mm stroke is long, use an external guide to prevent rod bending and side-load damage.
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 SAUF50X1000S-08A FAQ
It generates 982N push and 825N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s max) driven by an AC220V 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 window.
No, the built-in valve routes air but does not lock the piston. The default action retracts the rod when energized, which you can reconfigure to extend by repositioning the valve. To hold a load securely on air loss, install an external rod lock or pilot-operated check valve.
